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’s your vision prescription? And does that limit what contacts you can use?
A: There are a number of factors to consider when selecting contact lenses, and your vision condition is one of the most significant – as not all lenses are ideal for all prescriptions. If you have a more complicated or acute correction, then certain lenses such as toric (for astigmatism) or multifocal, are more readily available in monthly wearing schedules. Monthlies are composed of more rigid materials, which enable them to grant highly reliable vision correction at higher magnifications. Ultimately, your eye doctor will make the final prescription decision based on your vision needs and lifestyle preferences.
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.
