Q: How do allergies directly affect the eyes?
A: Chronic allergies may lead to permanent damage to the tissue of your eye and eyelids. If left untreated, it may even cause scarring of the conjunctiva, the membrane covering the inner eyelid that extends to the whites of the eyes. Ocular allergies can make contact lens wear almost impossible and are among the many causes of contact lens drop-out. Most common allergy medications will tend to dry out the eyes, and relying on nasal sprays containing corticosteroids can increase the pressure inside your eyes, causing other complications such as glaucoma.
Q: What are the advantages of daily disposable contact lenses?
A: There are two big benefits to daily disposable contact lenses. One is convenience. With dailies, there is no cleaning or storage, and no cost of lens cleaner. You just throw away the lenses after the day, and use a brand-new lens the next morning: nothing could be easier. The second benefit is comfort and health. Daily lenses tend to be more comfortable than monthlies, and also because they only stay in your eye for one day, there is no buildup of bacteria on the lenses that could cause infections or other problems. You also don't have to remember your replacement schedule and keep track of when to change your lenses: you have a new pair every day.
Q: How often should I have my glasses prescription checked?
A: The American Optometric Association recommends yearly eye-health examinations. As part of a comprehensive eye exam your optometrist will not only check your glasses prescription for changes, but he/she will also evaluate your eye health. Every patient needs to be regularly monitored for glaucoma and other eye conditions. For adults, it’s important to screen for age-related ocular diseases like cataracts and macular degeneration. Certain medical conditions, like diabetes, require annual eye-health exams, to monitor the potential side-effects they can have on the eyes. For children, visual dysfunction conditions like “lazy eye” and “crossed eyes,” can be missed with school vision screenings alone, so yearly eye exams are recommended for kids too. A regular complete eye examination is an integral part of routine health care.
