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.

How To Prevent “Mask Fog” on Your Glasses

If you wear glasses and a face mask, you’ve probably struggled with “mask fog.” Your lenses get all misty, requiring you to wipe your eyewear throughout the day. Below are a few strategies to help you prevent your eyeglasses from fogging up when wearing a mask.

But First, Why Do Glasses Fog Up?

Quite simply, condensation forms whenever moist warm air hits a cool surface. Your specs fog up when the mask directs your warm breath upward instead of in front of you — which is great for preventing virus transmission but bad for anyone with less-than-stellar eyesight.

Is Your Mask Well Fitted?

The mask should fit securely over your nose. Ideally, you’ll want to wear a mask with a nose bridge or one that can be shaped or molded to your face. When the mask fits properly, hopefully most of your breath will go through it, not out the top or sides.

Use Your Glasses To Seal the Top of Your Mask

This method works best with large, thick eyewear frames. By pulling your mask up higher on your nose and placing the lower part of your eyeglasses on the mask, you can get a snug fit that blocks your warm breath from escaping upward toward your eyewear.

Tape Your Mask to Your Face

You can always use tape to secure your mask across the bridge of your nose and the top of your cheeks. Use easy-to-remove tape, including adhesive, medical, or athletic. Just be sure to stay away from duct tape.

Soap and Water Help Prevent Fogging

This trick is one that healthcare professionals regularly turn to. All you need for this hack is soapy water (dish soap works best) and a microfiber cloth. Stay away from soaps with lotions in them as they can leave a thick residue, making it even harder to see.

Simply rub both sides of your lenses with a drop of soap, then buff the lenses with a soft microfiber cloth. This effective trick helps prevent your lenses from fogging up as a transparent, thin film of soap acts as a barrier.

Anti-Fog Wipes and Sprays

Another option is to purchase wipes and sprays designed to tackle foggy lenses. Read the fine print, as certain anti-fog solutions may not work as well, or may even damage lenses with coatings that minimize glare and fingerprint smudges, for example.

How to Disinfect Glasses to Help Prevent COVID-19

Coronavirus and Your Eyeglasses

Did you know that our glasses (this includes the lenses and the frame) can potentially transfer viruses, such as COVID-19, to our eyes, nose, and mouth? This is because viruses — as well as bacteria — are easily transferred from our surroundings to our hands and then from our hands to our glasses.

In fact, research has shown that coronavirus can remain on glass surfaces for as long as 9 days. If we’re not careful, we can easily touch our glasses then touch our eyes, nose, or mouth, thus continuing the contagion cycle.

The danger is even higher for people with presbyopia, age-related farsightedness that generally affects those aged 40 and above. Presbyopes who wear reading glasses tend to put them on and take them off several times throughout the day. What’s more worrisome is that this age group is at higher risk for more serious complications from COVID-19.

The good news is that disinfecting your glasses is easy! Let’s delve into ways you should and should not disinfect your lenses at home.

What NOT to Use to Cleanse Your Glasses

Many of us may have rubbing-alcohol at home, and although it may seem like a perfectly good idea to use it to disinfect your specs, we discourage you from doing so. It may be too harsh for your eyeglasses, especially if you have any special coatings on your lenses.

Other products you should stay away from include ammonia, bleach, or anything with high concentrations of acid, such as lemon juice or vinegar, which can damage lens coatings and some eyewear materials.

How to Safely Disinfect Your Glasses

Now that we’ve eliminated the substances and chemicals that should not be used on your lenses, let’s see what is safe to use to clean eyewear.

Dish Soap and Water

The absolute easiest and most efficient way to disinfect and clean your lenses is to use lukewarm water with a gentle dish soap. Massage the soap onto each lens, rinse, and dry using a microfiber cloth (not paper towels, as the fibers can easily scratch lenses). While you’re at it, don’t forget to include your frame’s nose pads and earpieces.

Lens Cleaning Wipes

Pre-moistened lens wipes are excellent for cleaning your glasses, as well as your phone, tablet and computer screen. They remove bacteria, dust, dirt and germs from your glasses and the formula restores shine to glass surfaces without leaving any streaks or residue. The durable material is tough enough to remove stains, while being gentle enough not to scratch your screens or lenses. Contact Preferred Eye Care to find out how you can access these.

So, In Summary:

  • Do not use rubbing alcohol to disinfect your glasses.
  • Avoid using household cleaners or products with high concentrations of acid.
  • Clean your glasses with a gentle dish soap and lukewarm water, or lens wipes.
  • Dry your glasses with a microfiber cloth to prevent smudging and scratching.

Disinfecting your glasses shouldn’t be stressful or worrisome. Just follow the easy steps above to protect your lenses and your health.

On behalf of everyone at Preferred Eye Care in Kokomo, Indiana, we sincerely hope you and your loved ones stay healthy and safe during this uncertain time.
