The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you. 

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts. 

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes. 

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens. 

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you. 

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Contact Lens Eye Exam Near You

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable. 

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.

8 Ways Your Eyes Change With Age

Our eyes and vision change with age. Your eye doctor can monitor these changes — some of which are a natural part of the aging process — and identify any eye conditions or diseases early enough to treat them and prevent vision loss. Read on to learn more about the different types of eye changes one may encounter with age.

Age-Related Eye Conditions and Diseases

Cataracts

If your vision is starting to get blurry, you may be developing cataracts. There are a few types of cataracts, but the one usually caused by aging is known as a “nuclear cataract”. At first, it may lead to increased nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and clouds your vision. As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color, and left untreated, it can eventually lead to blindness. Luckily, cataract surgery, where the cloudy lens is replaced with a clear lens, is an extremely safe and effective treatment option. 

Blepharoptosis

Blepharoptosis or ptosis is a drooping of the upper eyelid that may affect one or both eyes. The eyelid may droop only slightly or may droop enough to cover the pupil and block vision. It occurs when there is a weakness of the eye’s levator muscle that lifts the eyelid. This condition is usually caused by aging, eye surgery, or disease affecting the muscle or its nerve. Fortunately, blepharoptosis can be corrected with surgery.

Vitreous detachment

This occurs when the gel-like vitreous fluid inside the eye begins to liquefy and pull away from the retina, causing “spots and floaters” and, sometimes, flashes of light. This occurrence is usually harmless, but floaters and flashes of light can also signal the beginning of a detached retina — a serious problem that can cause blindness, and requires immediate treatment. If you experience sudden or worsening flashes and increased floaters, see Dr. Amit Shah immediately to determine the cause.

Other Age-Related Changes

In addition to the above eye conditions and diseases, the structure of our eyes and vision change as we get older. 

Presbyopia

Why do people in their 40s and 50s have more difficulty focusing on near objects like books and phone screens? The lens inside the eye begins to lose its ability to change shape and bring near objects into focus, a process is called presbyopia. Over time, presbyopia, also known as age-related farsightedness, will become more pronounced and you will eventually need reading glasses to see clearly. You may need multiple prescriptions – one prescription to enable you to see up close, one for intermediate distance, and one for distance vision. In that case, people often get bifocals, multifocals or PALs, and they can be combined with contact lenses as well.

Reduced pupil size

As we age, our reaction to light and the muscles that control our pupil size lose some strength. This causes the pupil to become smaller and less responsive to changes in ambient lighting. The result? It becomes harder to clearly see objects, such as a menu, in a low-light setting like a restaurant.  

Dry eye

Our tear glands produce fewer tears and the tears they produce have less moisturizing oils. Your eye doctor can determine whether your dry eye is age-related or due to another condition, and will recommend the right over-the-counter or prescription eye drops, or other effective and lasting treatments, to alleviate the dryness and restore comfort.

Loss of peripheral vision

Aging causes a 1-3 degree loss of peripheral vision per decade of life. In fact, one may reach a peripheral visual field loss of 20-30 degrees by the time they reach their 70s and 80s. While peripheral vision loss is a normal part of aging, it can also indicate the presence of a serious eye disease, like glaucoma. The best way to ascertain the cause is by getting an eye exam. 

Decreased color vision

The cells in the retina responsible for normal color vision tend to decline as we age, causing colors to become less bright and the contrast between different colors to be less noticeable. Though a normal part of aging, faded colors can at times signal a more serious ocular problem. 

Beyond the normal changes that come with age, the risk of developing a serious eye disease, such as age related macular degeneration and glaucoma, increases. Routine eye exams are essential to keeping your eyes healthy. Your eye doctor can determine whether your symptoms are caused by an eye problem or are a normal byproduct of aging.

Protect Your Eyes From Vision Loss: Diabetes Awareness Month

What Is Diabetic Retinopathy?

Diabetic Retinopathy (DR) is one of the most prevalent eye diseases affecting the working age population. It is thought to be caused by high blood sugar levels which, over time, damage the tiny blood vessels of the retina at the back of the eye, making them swell and leak. Left untreated, DR can lead to vision loss and eventually blindness.

Since diabetic eye disease is typically painless and shows no symptoms until its advanced stages, it’s critical to get your annual eye evaluation, as an optometrist can detect the developing signs early enough to prevent vision loss.

Symptoms of Diabetic Retinopathy 

Diabetics may not realize they have diabetic retinopathy, because it develops silently. As the condition worsens, it may cause: 

  • Blurred vision
  • Poor night vision
  • Colors to appear faded or washed out
  • An increased presence of floaters
  • Vision loss
  • Blank or dark areas in your field of vision

Diabetic retinopathy symptoms usually affect both eyes.

Risk Factors

If you are diabetic, caring for your eyes by undergoing routine eye exams and taking care of your body by controlling blood sugar levels are critical to preventing vision loss. There are several risk factors associated with diabetic eye complications, including: 

  • Poor blood sugar control
  • Smoking
  • High cholesterol 
  • High blood pressure
  • Pregnancy
  • Excess weight/obesity

Are There Any Treatments for Diabetic Retinopathy?

Today’s treatment options may improve your vision, even if you feel your eyesight has begun to deteriorate. Medications can be injected to reduce swelling, and laser surgery can be used to shrink and seal off swollen and leaking blood vessels — preserving and, in many cases, even improving vision. 

While certain treatments may work, frequent monitoring of your eyes coupled with managing your blood sugar levels can go a long way toward preventing or reducing diabetic retinopathy complications. 

If You Have Diabetes, Make Sure to: 

  • Control blood sugar and blood pressure to prevent long-term damage to the fine blood vessels within the retina.  
  • Keep a healthy lifestyle routine, especially during stressful times such as the COVID-19 pandemic. (Plus, while diabetics are in the high-risk category, your chances of developing serious COVID-19 related complications is lower if your diabetes is under control.)
  • Maintain a steady diet and exercise regimen to help the body and mind feel better. 
  • Quit smoking, if applicable; you can reach out to a medical professional for guidance.
  • Get yearly diabetic eye exams.

Preventing and managing diabetic retinopathy require a multi-disciplinary approach involving your eye doctor and other medical professionals. Your eye doctor will perform a comprehensive eye exam to determine whether you have diabetic retinopathy, assess its severity, and discuss preventative strategies as well as the latest treatment options.

New To Contact Lenses? Here Are Our Top 5 Tips!

For an estimated 56 million North Americans, contact lenses are the preferred form of vision correction. So if you’ve just started wearing contact lenses — you’re in good company.

Advice About Contact Lenses from Katy Ranch Eye Doctor: Dr. Amit Shah

Here are 5 tips to quickly help you adjust to wearing and caring for your new lenses so you can enjoy the many benefits they offer.

  1. Learn How to Tell if Your Contact Lens Is Inside Out

This is a common mistake many beginners make when inserting soft contacts. Place the lens on  your index fingertip and look carefully at its shape. The edge of the lens should be pointing upwards, like the rim of a teacup. If the edge is flared outward like a blooming flower, the lens is inside out.

Some contact lenses have tiny laser markings of numbers or letters. If the numbers/letters read correctly when you hold the lens on your fingertip, they are properly oriented and the lens is ready to be inserted.

  1. Never Use a Substitute for Contact Lens Solution

Your eye doctor will recommend the appropriate contact lens solution to suit your eyes and lenses. Some people have sensitivities and not all lens solutions are the same. 

Even if you run out of contact lens solution, don’t be tempted to rinse your lenses with water, and never use saliva to moisten or clean them.

Using substances other than the recommended contact lens solution to rinse or rewet your contacts can introduce harmful microbes to the eye and cause a serious infection. That’s why it’s best to remove your contacts before showering, swimming, or any other time they might get wet.

  1. If Your Contact Lenses Feel Uncomfortable, Take Them Out!

Some newcomers mistakenly think that if their contacts feel uncomfortable or gritty, they simply need to “get used to them.” Contact lenses are supposed to be comfortable, so if you are experiencing discomfort there may be something wrong.

With clean fingers, remove your contacts and rinse them, inside and out, with the solution or rewetting drops as recommended by your eye doctor. Dust or dirt could have gotten stuck between the lens and your eye, causing irritation. Flushing the lenses with contact lens solution will help remove the irritant.

If your eyes still feel irritated, don’t place the contact lenses back in your eyes. Instead, wait until they are no longer red or irritated, and try inserting them again. If the problem persists, contact your eye doctor.

  1. Wear Contact Lens-Friendly Makeup

Wearing makeup around the eyes can be a source of irritation and infection whether you wear contact lenses or not. Here’s what we recommend when it comes to eye makeup and contact lenses:

  • Choose hypoallergenic makeup.
  • If using a cream-based product around your eyes, choose a water-based formula instead of an oil-based one. 
  • Keep your eye closed during application to avoid makeup particles entering your eye. 
  • Don’t apply eyeliner or eyeshadow to the inner rims of your eyelids.
  • Replace eye makeup at least once every 3 months to minimize the growth and spread of bacteria.
  • Never share eye makeup with friends or family.
  • Remove your contact lenses before removing your makeup.
  1. Stick to the Hygiene Guidelines

We can’t emphasize this enough — always thoroughly wash and dry your hands before handling your contact lenses.

Try to avoid washing your hands with oily or heavily scented hand soaps, as they tend to cling to the surface of the lens and could irritate the eye. Additionally, if you touch moisturizers or lotions before handling your contact lenses you run the risk of some residual product adhering to the lens and clouding your vision.

After washing your hands, dry them using a lint-free towel. It’s harder to grasp contact lenses with wet hands, and — as mentioned above — lenses shouldn’t come into contact with tap water.

Bonus Tip: Get an Eye Exam

While all this advice can be very helpful, it doesn’t replace an in-person exam with your eye doctor.  Your eye doctor will advise you when to return for your next contact lens consultation. Following this schedule is the best way to ensure you can enjoy the freedom of contact lens wear.

If you are new to contact lenses (or not!) and have any questions or concerns about your eyes or vision, call (281) 238-5812. Texas State Optical Katy Ranch will be happy to schedule you for a contact lens exam and fitting.

5 Reasons To Wear Sunglasses In The Fall

When we think of fall accessories, the first things that come to mind are warm sweaters, plush scarves, or a snug pair of boots. Here’s another essential item to add to your list: a good quality pair of UV-blocking sunglasses. 

But why is it so important to protect your eyes when the sun seems to be hiding behind clouds on most days? While it may not make much sense, you’ll get a better understanding by the time you finish reading this article. So let’s dive in and explore the 5 reasons you should protect your eyes from the sun in the fall. 

Sunglasses: Summer Vs. Fall

The Sun’s Position

While we may squint more in the summer, the sunlight’s path to the eyes is more direct in the fall as the sun sits closer to the horizon. This places our eyes at greater risk of overexposure to UV rays. 

Changing Temperatures 

Irritating symptoms like dry, red, or watery eyes are often due to the season’s cool and harsh winds. The colder the air, the stiffer and thicker the eyes’ tear oils (meibum) become. Because thicker meibum doesn’t spread as evenly over the surface of the eyes, the tears can’t offer sufficient protection and moisture. 

Minimize irritation by shielding the eyes from cool winds with wraparound sunglasses.

UV Rays 

Exposing your eyes to the sun’s harmful ultraviolet (UV) rays is problematic year-round, as it can result in serious eye diseases, such as cataracts and macular degeneration. That’s why it’s important to wear 100% UV-blocking sunglasses anytime you’re outdoors, no matter the season.

Make sure to sport your sunnies even on cloudy days, as up to 90% of UV rays pass through clouds. Furthermore, outdoor objects like concrete and snow reflect a significant amount of UV rays into the eyes. 

Fall’s Dangerous Sun Glare 

Because the sun is positioned at a lower angle in the fall, it can produce a brutal glare that poses a danger for driving. Rays of light that reflect off of smooth surfaces like the metal of nearby cars can be so bright to the point of blinding the driver.  

You can combat this dangerous glare by wearing polarized sunglasses. These lenses reduce the glare’s harmful effects by filtering out horizontal light waves, such as the ones reflected by a shiny car bumper. 

Protection From the Elements

Aside from its drying effects, winds can carry dust, debris, and pollutants that can irritate the delicate areas in and around the eyes. Wear sunglasses to shield and block out irritants and certain allergens that drift in the autumn air.

Looking for Sunglasses Near You?

Here’s the bottom line: you need to protect your eyes by wearing sunglasses in the fall and year-round, no matter the season or climate. Investing in a stylish pair of durable, UV-protective sunglasses is — simply-put — a worthwhile investment in your eye health.

So if you’re looking for advice about a new pair of high-quality sunglasses for the fall, with or without prescription lenses, visit Texas State Optical Katy Ranch. If standard sunglass lenses are too dark for you at this time of year, ask us about green or brown tinted lenses; they transmit more light and contrast to the eyes than standard grey tints.  

We’ll be happy to help you find that perfect pair to protect your eyes, suit your lifestyle needs and enhance your personal style. To learn more, call (281) 238-5812 to contact our Katy Ranch eye doctor today.
