Studies show that blinking decreases during computer use, accelerating the rate of tear evaporation and increasing symptoms of dry eyes. In particular, computer monitors that are positioned above or level with the eyes cause the eyes to open wide, increasing the exposed ocular surface and resulting in a higher rate of tear evaporation. Unfortunately, most people either ignore their dry eye symptoms, or they mistakenly assume that their eyes are red and irritated because of eye strain or fatigue. Eyes, like the rest of the body, require moisture to stay healthy.
Tears protect, nourish, lubricate and cleanse the ocular surface.
In addition, the tear film prevents dehydration of the mucus membrane that coats the ocular surface and eyelids. Dry eyes can cause dry spots to form on the ocular surface, causing scratchiness and irritation. This polymer mimics the natural tear film, and can be used to replenish lubrication to dry eyes. Five minute breaks every hour can ease the impact of the constant glare. Use an anti-glare filter on your computer monitor.
