What Exactly is an Eye Chart?

If there’s one aspect of optometry that everyone recognizes, it’s the traditional eye chart, with its rows of big letters on top, which gradually become smaller the farther down you go. This chart is usually known as the Snellen chart.

Yet how much do you really know about this eye chart? Are all eye charts the same? How are these eye charts used? And when were they invented?

Here’s everything you need to know about eye charts and more!

What is an Eye Chart?

An eye chart is one of the tools your eye doctor uses to assess your eyesight. Based on how well you can see various letters on the chart, your optometrist will determine whether you have myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age-related farsightedness) or astigmatism, and will measure the prescription that will give you the clearest, most comfortable vision.

Are All Eye Charts The Same?

There are a number of variations to the standard Snellen eye chart. The one an eye doctor uses depends on the personal needs and abilities of the patient. For example, eye doctors will use charts with pictures or patterns for younger children who may not have learned to read or identify letters and numbers.

There are also certain charts that specifically measure distance vision, while others are better for measuring near vision.

History of the Snellen Eye Chart

The Snellen eye chart was developed by Dutch eye doctor Hermann Snellen in the 1860s. Before this standardized eye chart was developed, each eye doctor had their own chart that they preferred to use.

Having so many different eye charts made it impossible to standardize the vision correction available to patients. Eyeglass makers didn’t receive the defined measurements they needed to accurately design, manufacture and measure the optical prescriptions their patients needed.

For the first time, the Snellen eye chart allowed a person to provide a standardized prescription from any eye care provider they chose to any eyeglass maker, and get the same optical lenses to accurately correct their vision.

How The Snellen Chart Is Used in Eye Exams

The standard Snellen chart displays 11 rows of capital letters, with the first row consisting of a single large letter. The farther down the chart you go, the smaller the letters become.

Your Winter Park eye doctor will ask you to look through a phoropter – an instrument used to test individual lenses on each eye during an eye exam – and look at the Snellen chart placed 20 feet away. Your eye doctor will prescribe the lenses that provide you with the clearest and most comfortable vision.

In many offices, where 20 feet of space may not be available, you’ll be asked to view the chart through a mirror. This provides the same visual experience as if you were standing 20 feet away.

If you have 20/20 vision, it means you can see what an average person can see on an eye chart from a distance of 20 feet. On the other hand, if you have 20/40 vision, it means you can only see clearly from 20 feet away what a person with perfect vision can see clearly from 40 feet away.

If you have 20/200 vision, the legal definition of blindness, this means what a person with perfect vision can see from 200 feet away, you can see from 20 feet away.

Does 20/20 Visual Acuity Mean Perfect Vision?

No. While eye chart tests identify refractive errors, they can’t detect signs of visual skill deficiencies or diseases such as glaucoma, cataracts or macular degeneration. These are diagnosed using advanced equipment as part of a comprehensive eye exam with your local Winter Park eye doctor. Early diagnosis and treatment of eye conditions are essential to ensuring long-term vision and eye health.

Q&A With Your Local Optometrist

How do you keep your eyes healthy?

You only have one set of eyes – don’t take them for granted!

Make sure to implement the following habits for healthy eyes (and body). These include:

  • Eating a balanced diet rich in fiber, fruits and vegetables
  • Drinking plenty of water to hydrate your body and eyes
  • Not smoking, and avoiding 2nd-hand smoke
  • Wearing sunglasses to protect your eyes from ultraviolet (UV) rays
  • Maintaining normal BMI with regular exercise
  • Regular visits to your eye doctor as recommended

What health conditions can an eye exam detect?

A comprehensive eye exam can often detect certain underlying diseases that can threaten your sight and eye health, such as diabetes, high blood pressure, high cholesterol, tumors, autoimmune conditions and thyroid disorders. This is why having your eyes checked regularly is key. The earlier the diagnosis and treatment, the better the outcome and the higher your quality of life.

The Link Between Dry Eyes and Depression

The Link Between Dry Eyes and Depression 640×350Depression is a serious illness that impacts a person’s mood and emotional well-being. It creeps into all areas of a person’s life, and can become life-threatening if left untreated.

Not only does depression impact mental health; it can manifest as physical symptoms, too, like insomnia, chronic pain and inflammation, weight loss or gain and heart problems, among others. These physical problems can worsen depressive thoughts — sometimes leading to a vicious cycle.

Interestingly, many patients with depression also suffer from severe dry eye symptoms. The question is, how are these two conditions related?

What is Dry Eye Syndrome?

Dry eye syndrome, also known as dry eye disease, is a chronic condition that results from inadequate lubrication of the eyes. Ocular hydration is crucial when it comes to keeping your eyes healthy and your vision clear. Your tears are responsible for maintaining this necessary hydration, and in healthy eyes fulfill their unique mission each time you blink.

Your tear film is made up of three layers, consisting of oil, water and mucus. If any of these layers become compromised, inadequate tear quality or insufficient tear quantity can result and lead to a host of uncomfortable dry eye symptoms.

The most common dry eye symptoms include:

  • Dry eyes
  • Red or irritated eyes
  • Itchy eyes
  • Gritty eyes
  • Light sensitivity
  • Blurry vision

Can Depression Cause Dry Eye (or Vice-Versa)?

This is what researchers are trying to find out.

In a March 2022 study published in JAMA Ophthalmology, researchers examined the link between depression and severe dry eye symptoms. The study followed 535 dry eye patients for an entire year.

After a year, the patients who tested positive for depression had more severe dry eye symptoms than the patients who didn’t have depression. Their symptoms were measured based on the Ocular Surface Disease Index (OSDI), Brief Ocular Discomfort Index and composite dry eye disease sign score.

Additionally, severe depression was associated with more severe dry eye symptoms at baseline, six months, and one year.

The study concluded that depression was associated with more severe dry eye symptoms, which suggests that among patients with moderate to severe dry eye syndrome, those with depression may be likely to have more severe dry eye symptoms.

The researchers said further research is needed to learn exactly why people with depression have more severe dry eye symptoms than those without depression.

Could the sometimes debilitating symptoms of dry eye syndrome actually cause depression and anxiety?

A 2016 dry eye study published in Nature concluded that chronic discomfort and pain from dry eye symptoms can negatively affect the cognitive processes, sleep, mood and mental health. The researchers urged eye doctors to be aware of the higher incidence of dry eye syndrome in people with depression, whatever the underlying cause.

Can Antidepressants Cause Dry Eye Symptoms?

Yes. Antidepressants have been shown to increase dryness in the body, including the eyes. These medications work by blocking signals between nerve cells, which can result in insufficient tear production and dry eye syndrome.

If you’re taking an antidepressant, be sure to inform your eye doctor during your consultation.

Bloodshot Eyes – Should You Be Concerned?

You wake up in the morning ready to start your day, only to discover that your eyes are bloodshot. That might not be surprising if you stayed up late to finish a project, had too many drinks at a party or spent time in a smoke-filled room.

But bloodshot eyes can also signal an underlying eye problem. If your eyes appear red or bloodshot, make an appointment with an eye doctor for a comprehensive eye exam to determine the cause and to receive effective treatment.

Why Do I Have Bloodshot Eyes?

When blood rushes to the front of the eye, the tiny red blood vessels on the white of the eye dilate and become visible. This makes the eyes appear red and irritated.

So why do these blood vessels dilate, causing your eyes to look bloodshot?

Bloodshot eyes tend to be caused by:

  • Dry eyes
  • Irritants such as smoke, pollen and perfume
  • Lack of sleep
  • Excessive alcohol consumption
  • Spending too much time in front of the computer

Bloodshot eyes due to lifestyle and environmental irritants may disappear on their own, or you can try to relieve them with over-the-counter eye drops or liquid tears. Lifestyle changes, such as getting more sleep, cutting down on alcohol intake and limiting screen time can often be helpful. If allergies are the culprit, oral antihistamines and antihistamine eye drops may relieve symptoms.

At other times, underlying problems requiring prompt medical attention can cause your eye’s blood vessels to dilate. The following are some of these medical conditions:

Conjunctivitis

You’ve probably heard of “pink eye.” It’s another name for infectious conjunctivitis – an infection of the conjunctiva, the thin membrane covering the eyelid and the front surface of the eye.

There are two types of infectious conjunctivitis – bacterial and viral.

If your child has conjunctivitis, they’re not alone. About 12% of kids get bacterial conjunctivitis every year. This highly contagious condition affects children and adults. In addition to reddish eyes, the following symptoms are associated with conjunctivitis:

  • Bacterial conjunctivitis – irritated eyes, swollen eyelids, eye discharge, crusty eyelids and excessive tearing
  • Viral conjunctivitis – cold or flu-like symptoms, runny nose, fever, itchy eyes, excessive tearing

If you or your child are experiencing these symptoms, it’s important to schedule a prompt appointment with an eye doctor, who can diagnose whether the conjunctivitis is viral, bacterial or due to allergies.

Depending on the diagnosis, your eye doctor will prescribe antibiotic eye drops or creams to treat bacterial conjunctivitis. The viral form may run its course after a few days, but cold compresses and non-prescription eye drops may provide relief.

Dry Eye Syndrome

If your eyes are chronically bloodshot you may have dry eye syndrome (DES). Signs of DES include:

  • Dry, irritated eyes
  • Burning or stinging eyes
  • Discharge from the eyes
  • Light sensitivity
  • A feeling you have something stuck in your eyes
  • Blurred vision
  • Watery eyes

Dry eye syndrome is most commonly caused by a blockage of the tiny meibomian glands in the eyelids. These glands secrete oil that keeps eye moisture from evaporating too quickly. Without the oil, tears dry fast, leaving your eyes feeling dry, itchy and with a bloodshot appearance.

Too much screen time, aging, certain medications such as antihistamines, and medical conditions such as Sjogren’s syndrome can cause dry eye syndrome.

In addition to any medications or in-office treatments your eye doctor recommends, make sure to get plenty of hydration, take frequent breaks from digital screens and use a humidifier in your home.

Uveitis

In addition to bloodshot eyes, if you also experience blurred vision, see floaters or your eyes feel painful, you may have an eye inflammation called uveitis. The causes of uveitis include:

  • Autoimmune or inflammatory condition
  • Infection
  • Medication side effects
  • Cancer (in rare cases)

Unfortunately, uveitis symptoms can often be mistaken for something less serious. That’s the reason it’s important to get an eye exam if your eyes are bloodshot. Left untreated, uveitis can lead to serious conditions such as retinal scarring, cataracts and vision loss.

Depending on the cause and severity, your eye doctor may treat uveitis with prescription eye drops, steroid pills, injections or eye implants.

Eye Injury

It’s vital that all eye injuries receive immediate eye care from an eye doctor.

Even a minor eye injury can cause a big red blotch to form on the white part of the eye (sclera). The cause is a broken blood vessel or a subconjunctival hemorrhage.

Although the appearance of this blood looks severe, and can make the entire white part of the eye appear bright red, a subconjunctival hemorrhage is usually painless and doesn’t cause vision loss. Any time you notice excessive blood on the eye following an eye injury, schedule an appointment with an eye doctor to assess the health of your eye.

Glaucoma

In rare cases, bloodshot eyes may signal the presence of glaucoma – a leading cause of vision loss and blindness.

While some types of glaucoma don’t show symptoms in the early phases, bloodshot eyes can indicate the type of glaucoma that requires immediate medical care. This disease causes damage to the optic nerve due to excessive pressure within the eye. When this pressure suddenly rises, the eye’s blood vessels become dilated and visible, making the eye appear red.

If you have bloodshot eyes and/or have the following risk factors for glaucoma, immediately schedule an appointment with your eye doctor.

  • Family history of glaucoma
  • Aged 60+
  • African American, Asian or Hispanic
  • Diabetes
  • High blood pressure

Q&A With Your Local Optometrist

Can I get bloodshot eyes after LASIK surgery?

LASIK surgery is highly effective minimally invasive laser eye surgery that can correct refractive errors, but like all surgical procedures, it can have side effects. Your eyes may be bloodshot or you could see halos from a few days to three weeks after surgery. Additionally, you may experience other dry eye symptoms. Eye drops and liquid tears can alleviate these symptoms, but if you have any concerns about your eyes following LASIK surgery contact your eye surgeon.

What Should I Expect from a Glaucoma Exam?

If you have a family history and/or other risk factors for glaucoma, and if your eyes look bloodshot, consider scheduling a glaucoma exam. Your eye doctor may perform the following tests:

  • Tonometry – eye pressure test
  • Gonioscopy – to see how fluid is draining out of your eye
  • Vision field test – to examine the functioning of the optic nerve
  • Dilated pupil exam – to detect any damage to the optic nerve
  • Retinal photo or OCT – digital examination of the retina and optic nerve health

Regular Contact Lenses Not Working for You? Consider Scleral Lenses

Woman wearing scleral lensesIf you have dry eye syndrome, a corneal transplant, keratoconus or who simply find conventional contacts uncomfortable to wear, you may want to try scleral contact lenses. Scleral lenses are larger than standard lenses and vault over the entire surface of the cornea. Because the lens sits firmly on the eye, it offers more comfortable and stable vision than traditional lenses.

Eye Problems That Can Make Contact Lens Wearing Difficult

If your cornea is irregularly sized or shaped, standard contact lenses may not fit you properly or may move when you blink. Furthermore, standard contacts can also cause or exacerbate dry eye symptoms, such as red, irritated, itchy or dry eyes.

Below are common eye conditions that can make contact lens wearing a struggle:

  • Keratoconus
  • Dry eye syndrome
  • Astigmatism
  • Corneal transplant
  • Post-refractive surgery (i.e. LASIK)

Why are Scleral Lenses a Comfortable Alternative?

These oversized lenses provide relief, clear vision, and visual rehabilitation for dry eye, keratoconus, corneal degeneration, eyelid abnormalities, and corneal ectasia, among other conditions. That’s because the custom-designed scleral lenses are fitted to your unique eye shape, providing a superior level of comfort.

Moreover, a fluid reservoir between the lens and the cornea optically neutralizes any corneal irregularities and hydrates the ocular surface, providing a moist and comfortable environment between the eye and the lens.

How Large are Scleral Lenses?

The average size of regular contact lenses is 9mm, which is smaller than the cornea, whereas scleral lenses measure between 14.5mm to 24mm in diameter. This allows the scleral lens to form a dome over the cornea, creating a cushion of tears between the lens and the eye.

What Happens During a Scleral Lens Fitting?

Scleral lenses are custom-fit to each person’s unique eye shape, corneal curves, and contours, providing unparalleled comfort. Their size and shape also ensure stability.

To design the lenses, your Aloma Eye Associates Scleral Contacts Lens Center eye doctor in Winter Park will take exact measurements of your cornea through a process called corneal topography. This process ensures that your personal pair of scleral lenses allows the right amount of light in and sits stably on the eye, thus offering superior vision, all-day ocular hydration, and increased comfort.

Schedule an appointment with Dr. Amy Ward and talk to us about getting fitted with scleral lenses.

Our practice serves patients from Winter Park, Baldwin Park, Waterford Lakes, and Alafaya, Florida and surrounding communities.

 

Frequently Asked Questions with Dr. Ward

 

Q: Can Scleral Lenses Treat or Cure Keratoconus?

  • A: While scleral lenses aren’t a cure for keratoconus, they are highly effective at correcting vision if you have irregular-shaped corneas or cone-shaped corneas.Because those with keratoconus have irregular, cone-shaped corneas, glasses and standard contact lenses cannot conform to the shape of the eyes and thus cannot adequately correct the patients’ vision. The best solution, therefore, is scleral contact lenses, since they sit on the sclera without touching the cornea and deliver maximal clarity while being perfectly comfortable in most cases.

Q: Can Scleral Lenses Help Improve Vision Following Corneal Transplants?

  • A: Though corneal transplants have a high rate of success, it can take more than a year for the eye to recover from surgery. This is because the eye needs time to adapt to the new cornea, during which time nearsightedness or astigmatism may develop. For this reason, scleral lenses are the ideal choice for clear and comfortable vision following a corneal graft.

Stay Active and See Better With Scleral Lenses

Stay Active and See Better With Scleral Lenses 640×350Scleral contact lenses have long been the way to provide clear and comfortable vision to people with keratoconus, severe dry eye syndrome, irregularly shaped corners and patients recovering from corneal transplants and refractive surgeries.

But did you know that scleral lenses are also a great option for active people who need their lenses to sit securely and not pop out? Many people find that traditional contact lenses don’t provide the stable and clear vision required for their active lifestyle. This is especially true for athletes with high astigmatism who want to achieve a greater level of clarity comparable to LASIK surgery.

Whether you like to run marathons, go skiing or play sports that require sharp vision, scleral lenses can provide the vision correction and peace of mind you’ve been seeking.

What Makes Scleral Lenses Different?

Scleral lenses are hard, gas-permeable contact lenses that settle on the eye in a more stable position than regular soft or hard contacts. That’s because scleral lenses have a larger diameter than standard lenses, so they’re less prone to falling out or moving on the eye.

In addition, these lenses vault over the cornea to rest on the sclera, the whites of the eyes, on a cushion of fluid, providing additional comfort. Your eyes stay hydrated when exposed to harsh winds during winter sports or in hot and dry conditions.

These features make sclerals a good option for active people and athletes.

What Else Are Scleral Lenses Used For?

Scleral lenses are the go-to lenses if you have an irregularly shaped cornea or keratoconus, which causes the lens to thin, bulge and develop a cone-like shape. As keratoconus progresses, patients often can’t achieve clear vision from eyeglasses or regular contact lenses.

The fact that scleral lenses are custom-designed to fit a patient’s eyes can make them the best option for people who can’t wear traditional hard or soft lenses.

Who Is a Good Candidate for Scleral Lenses?

The following people may find a particular benefit from scleral lenses:

  • Active people and athletes who need clear vision and want contacts that will stay firmly in place
  • People with irregular corneas, such as keratoconus
  • Those with dry eye syndrome
  • Post-corneal transplant patients
  • Those who have poor vision due to complications after eye surgery.

Can You Play Sports with Scleral Lenses?

Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. Many wearers also find them more comfortable than other contact lenses. This makes sclerals ideal for most sports, including baseball, basketball, cycling and skiing.

There are, however, some direct contact sports, such as karate, boxing and wrestling, where sclerals aren’t recommended due to the risk of eye injury if the lens is damaged.

Do Scleral Lenses Treat Keratoconus?

Scleral lenses aren’t a cure. However, sclerals are highly effective at correcting vision if you have irregular-shaped corneas because the lenses vault over the cornea and rest on the sclera, compensating for the misshapen cornea.

If you love sports, live an active lifestyle, have an irregularly shaped cornea or dry eyes, consult with Dr. Amy Ward at Aloma Eye Associates Scleral Contacts Lens Center to see whether scleral lenses are the right solution for you.

Our practice serves patients from Winter Park, Baldwin Park, Waterford Lakes, and Alafaya, Florida and surrounding communities.

Frequently Asked Questions with Dr. Ward

Q: How Can Scleral Lenses Improve An Athlete’s Vision?

  • A: Athletes are typically exposed to challenging environmental conditions, such as dust, chalk, sand and wind. These can all interfere with the comfort of wearing soft contact lenses. Because scleral lenses provide a seal over the eye’s surface, the eyes are better protected from the elements, allowing athletes more stable, clear, crisp vision.

Q: Do Scleral Lenses Cure Keratoconus?

  • A: No. Custom-designed scleral lenses help patients with corneal irregularities, like astigmatism and keratoconus, achieve dramatic improvements in visual acuity and comfort. These lenses vault over the cornea and rest on the sclera, thus creating a new optical surface. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment, ensuring optimal vision and comfort for those with keratoconus.

5 Ways to Prevent Dry Eyes During Air Travel

Dry Eye Air Travel Tips 640×350While traveling can be taxing on the entire body, the eyes are especially vulnerable — particularly when wearing a mask to protect from COVID. When traveling by plane, the dry air can cause your eyes to become red, parched and irritated. While you can’t control all variables during your travels, eye specialists have discovered a number of ways to reduce the chances of experiencing the unpleasant symptoms of “travelers’ dry eye.”

Here are five suggestions for preventing dry eye from affecting your vision.

Drink plenty of water. If your body isn’t properly hydrated, it will have a tougher time increasing tear production in a dry atmosphere. Humidity levels on planes are typically below 20%, which is lower than the Sahara Desert! Keep your eyes moist and comfortable by drinking plenty of water before, during and after your flight.

Wear your glasses. Since contact lenses remove moisture from your eye’s surface tear film, they can contribute to dry eye. Wearing your glasses can help keep your eyes moist.

Wear a sleep mask. Even when your eyelids are closed, your eyes might lose moisture, which happens frequently when you sleep. On a plane, a sleep mask can help prevent additional dryness.

Use hydrating eye drops. When you’re in a dry environment, a good hydrating eye drop can provide a brief respite.

Make sure your face mask fits snugly. When a person’s breath rises upward it can dry out their eyes. A face mask that fits securely around the bridge of the nose can prevent air from reaching the eyes.

Is dry eye making you miserable, especially when traveling? Put an end to the discomfort and struggle by contacting Aloma Eye Associates Dry Eye Center. Our dedicated eye doctors will get to the bottom of your dry eye and provide effective, lasting treatment.

Our practice serves patients from Winter Park, Baldwin Park, Waterford Lakes, and Alafaya, Florida and surrounding communities.

Frequently Asked Questions with Dr. Ward

Q: Can dry eye be cured?

  • A: In some cases, yes. A range of successful treatment options can help manage dry eye for long-term relief. Your eye doctor can also provide in-office treatments for more advanced forms of dry eye disease.

Q: What type of treatments are available for dry eye?

  • A: Depending on the cause of the dry eye, treatment options include:
    – Lubricants
    – Punctal plugs
    – Topical steroids
    – Warm compresses
    – Protective eyewear
    – Intense pulse light
    – Switching to medications that don’t cause dry eye symptoms

8 Benefits of Wearing Scleral Lenses

Woman Wearing Scleral LensesScleral contact lenses are rigid gas permeable lenses with an extra-wide diameter. As opposed to standard contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface before coming to rest on the white part of your eye (your sclera).

They are custom-fit to your eye and are perfect for those with hard-to-fit eyes, astigmatism, keratoconus, severe dry eye, or for those simply seeking more comfort when wearing contact lenses.

Here are 8 reasons why scleral contact lenses may be beneficial for you:

1. Clear Vision For Those With Keratoconus

Keratoconus (keh-rah-toe-cone-us) is an eye disorder in which the round dome-shaped cornea progressively thins and causes a cone-like bulge to develop. The irregular, cone-shaped corneas cannot be properly corrected using glasses or traditional contact lenses. Scleral lenses, on the other hand, sit comfortably sit on the sclera without touching the cornea, while providing sharpness, clarity and comfort in vision.

2. Great Solution for Hard-to-Fit Eyes

Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition (i.e. keratoconus or astigmatism) or complications following surgery (such as LASIK), can occasionally develop vision problems that cannot be corrected with glasses or soft contact lenses. Consider scleral lenses for a comfortable, secure fit, and improved vision.

3. Relief for Dry Eyes

Though generally used to treat corneal irregularities and refractive errors, scleral lenses can also provide immense relief to dry eye patients.

These custom-designed lenses vault over the cornea and rest on the sclera while avoiding the cornea. The liquid reservoir between the lens and the cornea provides a continuous moist environment that protects the cornea and provides relief for those with dry eyes.

4. Stable Vision

The lenses’ super-size diameter ensures that they stay centered and stable on your eye, which also prevents them from popping out easily, even if you play sports or lead an active lifestyle.

5. Wide Visual Field and Reduced Glare

Because of their large diameter, scleral lenses are more stable and have a wider optic zone than other lenses. They offer a more accurate perception of peripheral vision and help minimize glare and sensitivity.

6. Eye Protection

The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution if you suffer from eye allergies.

7. Long-Lasting Lenses

These rigid gas permeable contacts are made of high-quality, durable materials made to last for the long haul. Refer to your eye doctor to discuss the right time to replace your lenses.

8. Cost-effective

Because they’re custom fit, the cost of scleral lenses is usually higher than standard contact lenses. However, sclerals last up to 2 years, so they’re more cost-effective in the long term. Your insurance coverage may pay for scleral lenses if you have a corneal disease or other eye condition.

Ready to Try Sclerals?

If you’re looking for an eye doctor in Winter Park who can assess whether scleral contacts are right for you, look no further than Aloma Eye Associates Scleral Contacts Lens Center. Whether your contacts are uncomfortable or you have a corneal irregularity that makes wearing regular contacts impossible, we welcome you to contact us today to discuss whether sclera lenses are right for you!

 

Frequently Asked Questions with Dr. Ward

Q: Why are regular lenses uncomfortable for people with dry eye syndrome?

  • A: When the contact lenses dry out, they can create discomfort, especially if the eye is also dry. People with dry eye syndrome suffer from itchy, red, burning or a gritty feeling in the eye. That is why scleral lenses are better for dry eye patients than regular contact lenses because they have a wider curve to hydrate the eye and keep it moist, alleviating dryness.

Q: Why is it difficult for people with keratoconus to wear traditional contact lenses?

  • A: Keratoconus is caused by a weakness in the cornea that causes it to bulge forward and compromise vision. Contact lenses help keratoconus patients see properly, and yet, because of the irregular shape of the cornea, it can be difficult to fit them with standard contact lenses. Since scleral lenses are wider and are custom-designed, they are usually the contact lens of choice to correct vision in keratoconus patients.

Our practice serves patients from Winter Park, Baldwin Park, Waterford Lakes, and Alafaya, Florida and surrounding communities.

What’s The Link Between Dry Eye and Accutane (Acne Medication)

Teen with severe acne wearing maskAccutane, generically called isotretinoin, is an oral medication that is widely prescribed to treat severe acne that hasn’t responded to other treatments.

Although this drug often does a great job of reducing acne, it has several potential side effects that can affect many bodily systems, including the eyes.

Isotretinoin and Dry Eyes

Isotretinoin works by decreasing the size of the oil glands that secrete oil onto the skin. By reducing the production of the facial oils, the pores become less clogged and the amount of acne diminishes.

As the medication travels through the bloodstream, it also penetrates the eyelids’ meibomian glands, which produce the oil for tears.

These meibomian glands, which line the inner portion of the eyelids, play an important role in keeping the eyes hydrated and healthy by secreting oil to stabilize the tear film. When Accutane suppresses their function, the oil layer in the tear is inadequate, allowing excessive tear evaporation. As a result, the eyes dry out.

A 2012 study published in JAMA Dermatology analyzed the ocular effects of isotretinoin and concluded that taking it places patients at a significantly higher risk of experiencing a range of adverse ocular effects.

Common ocular conditions that were associated with this acne medication were dry eye syndrome, blepharitis, conjunctivitis, photosensitivity, contact lens intolerance and papilledema.

The researchers found that the ocular conditions resulted from changes to the cornea, eyelids, retina and meibomian glands. Additionally, the drug was found in the tear film and caused increased ocular irritation.

The good news is that these effects are often temporary, and resolve within a few months after completing treatment. One study, published in Optometry and Vision Science (2015), however, found that 1% of patients developed permanent meibomian gland dysfunction after taking isotretinoin.

 

How a Dry Eye Optometrist Can Help

Some dermatologists will refer their patients to an optometrist for a dry eye evaluation before prescribing isotretinoin to treat acne. If the patient already has signs of ocular surface disease or is taking other medications that interfere with tear production, the doctor may decide against prescribing isotretinoin.

We can help by thoroughly assessing your ocular condition to help your dermatologist determine the best acne treatment for you, as well as help you manage your dry eye symptoms.

If you or a loved one is currently taking or has taken isotretinoin and is experiencing symptoms of dry eye syndrome such as eye irritation or burning eyes, we can offer lasting treatment and solutions.

Frequently Asked Questions with Dr. Ward

6 Things To Know About Keratoconus

happy couple in winterKeratoconus is an eye disease that causes the cornea, the clear dome-shaped front surface of the eye, to become misshapen and bulge. This progressive disease usually occurs in both eyes and affects approximately 50-200 in every 100,000 individuals.

People who have keratoconus often experience problems like blurred vision, distorted vision, night blindness and sensitivity to light. Clear vision correction for keratoconus can be challenging to achieve because the irregular corneal shape makes it difficult or impossible for standard eyeglasses or contact lenses to provide you with sharp vision.

Thankfully, there are ways for people with keratoconus to achieve clear and comfortable vision, something we explore below, along with several other key points about keratoconus.

1. Everyone has different risk factors for developing keratoconus

Some risk factors for developing keratoconus include:

  • Hereditary predisposition
  • Eye rubbing
  • Other medical conditions like Down syndrome, allergic dermatitis and connective tissue disorders
  • Eye inflammation

2. Keratoconus can develop at any age

Although most cases of keratoconus are first diagnosed in adolescence or young adulthood, it can appear during any stage of life. That’s why regular eye exams are crucial, even if your vision seems clear and your eyes appear to be healthy.

3. Early diagnosis is key

This rings true for almost every eye disease, especially keratoconus. Catching it early in its tracks can allow the eye doctor to implement various treatments to slow down its progression during the initial stages, when this condition tends to worsen more rapidly.

4. Keratoconus progresses at different rates throughout life

Keratoconus progression varies from person to person, and one person can experience varying degrees of progression in each eye. Some patients live with mild keratoconus their entire lives, while other patients develop severe keratoconus early on.

Often, optometrists will recommend that patients undergo certain procedures to strengthen the cornea and prevent or slow down further progression.

5. Keratoconus can be treated with surgery or scleral contact lenses

Corneal cross-linking surgery is an effective option to provide enhanced strength to the cornea and is the only FDA-approved method of stopping or slowing keratoconus progression. However, if the condition develops into severe keratoconus, a corneal transplant may be the best option for treating the condition and restoring clear vision.

Scleral contact lenses offer another option to surgery. They are ideal for patients with early or moderate levels of keratoconus because they safely and effectively correct vision without irritating the misshapen cornea. In fact, studies have shown that patients with keratoconus who wear scleral contact lenses greatly reduce their risk of needing keratoplasty (corneal transplant surgery).

The large diameter of scleral contact lenses allows them to vault over the sensitive corneal tissue and then also coat the cornea in a nourishing reservoir of fluid for optimal comfort and visual clarity. Because eye rubbing and corneal irritation are significant risk factors for the progression of keratoconus, the protective qualities of scleral lenses can help to minimize keratoconus progression.

6. You can live a normal life with keratoconus

With the proper care and treatment from your optometrist, keratoconus shouldn’t stop you from living your life to the fullest. Although it can be discouraging to experience vision problems that can’t be resolved with standard lenses or glasses, know that there are other options available.

At Aloma Eye Associates Scleral Contacts Lens Center, we help patients with keratoconus and other corneal abnormalities achieve crisp and comfortable vision using scleral contact lenses and other specialty lenses.

Blinking Exercises for Dry Eye

Blinking Exercises 640×350Did you know that the average person spends around 7 hours a day looking at a screen? The glare and reflections from computer, smartphone, and tablet screens can reduce blink rates by as much as 60%. When we concentrate intensely we tend to blink less, which can, in turn, lead to dry eye syndrome.

Symptoms of dry eye syndrome include red and dry eyes, irritated eyes, blurred vision, painful or stinging eyes, light sensitivity and mucus around the eyes.

Blinking helps keep our eyes healthy and comfortable. With every blink, the ocular surface is cleaned of debris and lubricated, so less blinking means more irritation and dryness.

Below are a few blinking exercises to help you ensure that your eyes remain lubricated and refreshed throughout the day.

Blinking Exercises

Blinking exercises are simple to do and can be seamlessly integrated into your daily routine. These exercises should be done a few times an hour. Try alternating between the 2 exercises below.

1. Close-Pause-Pause-Open-Relax

  1. Without squeezing, gently close your eyes.
  2. Pause and keep your eyes closed for 2 seconds.
  3. Gently open your eyes and relax them.
  4. Repeat 5 times

2. Close-Pause-Pause-Squeeze-Open-Relax

  1. Without squeezing, gently close your eyes.
  2. Pause and keep your eyes closed for 2 seconds.
  3. While keeping your eyes closed, squeeze your eyelids together slowly and gently.
  4. Gently open your eyes and relax them.
  5. Repeat 5 times

The Importance of Fully Blinking

It’s important to fully blink to completely lubricate your eyes. If you’re only partially blinking, it can render your dry eye symptoms worse.

To find out whether you are fully blinking, just look at your eyes in the mirror. If they feel dry or appear red, or if you see a horizontal stripe of red blood vessels across your eyes, then you have been partially blinking.

If you’ve incorporated blinking exercises into your routine but are still experiencing eye irritation, you may have dry eye syndrome. We can diagnose the underlying cause of your symptoms, and offer a variety of dry eye treatments to alleviate any discomfort. Schedule an eye exam with Aloma Eye Associates Dry Eye Center today to receive effective, long-lasting relief.

Aloma Eye Associates Dry Eye Center serves dry eye patients from Winter Park, Baldwin Park, Waterford Lakes, and Alafaya, Florida and surrounding communities.

Frequently Asked Questions with Dr. Ward

Q: What is dry eye syndrome?

  • A: Dry eye syndrome is caused either by insufficient tears or poor tear quality. Every time you blink, you leave a thin film of tears over the surface of your eyes. This helps keep your vision clear and your eyes healthy. If your tears don’t keep the surface of your eye moist enough, you will experience dry eye symptoms. Some medical conditions, certain medications, dysfunctional glands, allergies and environmental irritants can all cause dry eye symptoms.

Q: What are the symptoms of dry eyes?

  • A: Symptoms of dry eye include irritation; a gritty, scratchy or burning sensation; blurred vision; excessive tearing; and/or a feeling of having something stuck in the eye.
