UV EXPOSURE AND COMPUTERS By Dr. Martha Jay, Ophthalmologist at Lakeshore Eye Care Professionals, S.C. in Mequon & Saukville, Wisconsin
The development of cataracts and macular degeneration is associated with UV exposure. That is why we recommend good sunglasses for everyone when outside on sunny days. Most sunglasses available today offer 100% UVA and B protection. But beware of very dark older sunglasses, perhaps picked up at a secondhand store. Those older products block the brightness of sunlight but not the harmful UV rays.
What about your computer? Are you exposing yourself to harmful UV rays every day when using your computer or laptop? The answer is: “No.” Even the older CRT monitors, those large box shaped monitors that are becoming less common, release only a very low level of UV radiation. A lifetime using such a device poses no damage to your eyes. The newer LCD screens, those flat screens that are on laptops and most newer computers, emit no UV light.
So no need to wear sunglasses while working on your computer. That does not mean that computer work is without eye problems. When using a computer, we all tend to stare or blink less. This causes dryness that makes the eyes feel fatigued and can blur your vision. Taking short breaks by focusing farther away, thinking to blink more often and adding artificial tears generally is all that is needed.
Another eye-related computer problem has to do with bifocals. Using a bifocal with a computer at desk level requires that you lift your head, putting your neck in an uncomfortable position. A solution is a separate pair of glasses just for computer use. This allows you to view the screen straight ahead, relaxing your neck and you too.
