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: Do I need to use an anti-glare filter on my computer screen?
A: Anti-glare filters for the computer can be effective at reducing reflections from the computer screen, which may improve comfort for some. However, computer screen anti-glare filters will not help if you have eye fatigue due to visual problems associated with the constant focusing and refocusing of the eyes while working on computers. An evaluation with your eye doctor may determine that you may need prescription computer eyewear.
