Do’s and Don’ts of Contact Lens Wear

Contact lenses are great medical devices that help over 30 million people in the world improve their vision. However up to 90% of contact lens wearers do not follow the proper care instructions for their lenses. And that can lead to bad news for your comfort and vision. Here are some tips on good lens care and hygiene.

Replacement Schedule:
Depending on the brand, soft contact lenses come in monthly, biweekly, or daily replacement schedules. It is important to adhere to the recommended schedule. Extending the life of your lenses can cause excess build up of protein, allergens, pollutants, or mircoorganisms that can irritate your eyes causing dryness and discomfort or worse an eye infection. Daily disposables are trending more these days since they eliminate the build up of debris allowing for better comfort. Daily lenses also result in better compliance for patients who forget when it is time to replace their lenses after several weeks. I recommend daily disposables especially to my younger patients who have very active lives.

Contact lens solution and how to clean your lenses:
Always wash your hands with soap and water before handling your contacts and eyes. This is how microorganisms contaminate your eyes and lead to irritation or infection. When removing your lenses at the end of the day make sure to rub with multipurpose solution with your fingers for 20 seconds and then rinse them before placing them into the case overnight. Be sure to only use contact solution to clean your lenses. Multipurpose solution is designed to disinfect lenses unlike water, saline, and/or rewetting drops. Never reuse old solution and never top off old solution in your case. It is just as important to clean the case and allow them to air dry during the day. Remember to replace your case every 3 months as it can be another source of microbial contamination. Conveniently, companies usually include a new case in the package of each bottle of solution.

There are various types of contact solutions on the market these days. Multipurpose solutions can be used to rinse, clean, condition, and store contacts. Examples of multipurpose solutions are Bausch and Lomb’s Biotrue and Alcon’s Opti-Free. Also available are products such as Clear Care by Alcon which uses hydrogen peroxide to clean and remove debris from lenses. They require a specialized case and takes 6 hours to neutralize the peroxide into saline. Beware that if you place the solution directly into your eyes it will result in redness and stinging – a painful mistake! However, once the peroxide is neutralized after 6 hours it is perfectly safe to directly place the lenses onto your eyes. Hydrogen peroxide solutions are also preservative-free which is great for patients who experience sensitivity to other products.

Do not sleep in your lenses!
I always stress to my patients the dangers of sleeping in contact lenses. The cornea is the top layer of the eye on which the contact lens sits on. Wearing contacts normally reduces oxygen transmission to the cornea from the open air. By closing your eyes and sleeping you deprive them of oxygen even further. The cornea can swell thereby causing blurry vision. You are also more likely to get an infection from any bacteria harboring on your lenses and then sitting on your eyes overnight. I tell my patients to remove their lenses earlier in the evening before they get tired to avoid accidently falling asleep in them.

Update your contact lens prescription annually
Lastly, contact lenses require a prescription. Your eye doctor will exam your eyes to make sure they are in good health as well as check if your glasses and contact lens prescription have changed. Many times corneal issues are detected during routine exams.Visiting your doctor annually and following these simple rules of contact lens care will keep you and your eyes looking sharp!

What’s trending for contact lens patients with dry eyes?

Contact lenses have come a long way in a short amount of time.  The largest trend I’ve seen in the past few years has been a shift to daily disposable lenses.  These days every contact lens manufacturer has their own stockpile of daily disposable lenses, each with their own strengths.

There are many benefits to wearing a daily disposable lens.  We get build up on our lenses everyday such as microorganisms, allergens, pollutants, and tear film protein.  A daily lens eliminates re-inserting those potentially harmful agents and prevents infections.  Additionally, the debris collected on a contact lens over time can cause discomfort which is why you feel the need to throw away your monthly lens before the 30 days is up.  Another advantage to daily disposables is the convenience factor.  Most patients do not like to bother with rubbing, rinsing, and storing their lenses every single night.  Some patients even find irritation with certain cleansing solutions.  Many of my patients frequently travel for business and they have found it a relief to do away with carrying solution on their journey.  Thus health, comfort, and convenience are the chief reasons I prescribe dailies.

While many of my patients are happy in their current monthly and biweekly contact lenses, there are times when someone will complain about dryness and comfort.  These may be middle aged patients who suffer from dry eyes or professionals who work on a computer all day.  It is also possible that the patient has already converted into a daily lens but still does not find significant relief.  In these cases there is a lens that comes to mind where I have found success in providing all day comfort.  Last year Alcon debuted Dailies Total 1.  The lens contains the latest in comfort evolution called Water Gradient technology.  This mean that the lens has an increased amount of water content on the front and back surface which gives a cushion of moisture on the eye.  Patients respond extremely well to the product and love wearing contacts lenses again. The best part of Dailies Total 1 is that it doesn’t sacrifice health benefits such as oxygen permeability.  According to Alcon it is six times more breathable than the other daily disposables.  This makes prescribing Total 1 a win for both patients and doctors.

If you would like to try Dailies Total 1 and see how much better your  contact lens wearing experience can be then make an appointment with us at your convenience.  We look forward to taking care of you and your eye care needs!

GUARDING AGAINST GLAUCOMA

Regular Eye Exams Are Key in Fighting a Disease That Can Rob You of Your Sight

Called the “silent thief of the night,” glaucoma can creep up unnoticed, especially in its early stages. In fact, people who have glaucoma – the name given to a group of diseases that damage the eye’s optic nerve – might not even know they have it until it’s too late. The disease starts with imperceptible blind spots at the edges of the field of vision, progresses to tunnel vision, and then ultimately leads to blindness if left untreated. In fact, glaucoma creates at least some vision loss in more than half of the approximately 2.5 million Americans with the disease and is the second leading cause of blindness. Read More

A Remedy for Wrinkled Foreheads

A very effective advertising campaign by a popular fried chicken restaurant chain is promoting boneless fried chicken by showing the panicked expressions of people who believe they have eaten the bones of the chicken when they see their empty plate. One particularly gentleman sports a deeply wrinkled forehead that rivals that of a Shar-Pei to make the point.

While having a wrinkled forehead may be great for humorous ads, it can be a negative in our everyday social interactions. Wrinkles can convey a sense of worry, and that can be interpreted as a person lacking confidence. Or, they can communicate a general sense of unease. Read More

Eliminate Angry Face: Your Botox and Surgery Options

Recently, a popular local radio station hosted a contest for the angriest looking face at rest. I immediately thought of an old acquaintance of mine who had the heaviest, most angled brows of anyone I knew. Even when he was happy, he looked angry.

No More Drooping Eyelids

I recently visited a friend who was watching the movie Stand and Deliver, one of the prototypical inner city schoolteacher movies. It reminded me of one of my first patients, a schoolteacher trying to make a difference in the lives of struggling urban youth. Although the patient was tall, eloquent, and otherwise commanding in his presence, he had developed drooping upper eyelids. When I first met him, I could hear the frustration in his voice as he described how his students did not respect him because they always thought he was asleep. At a follow-up appointment, several months after a simple procedure to lift his lids, he elatedly told me how his relationships with his students had blossomed as if a curtain had been lifted.
