"Are vision related problems common among computer users?"
"So quickly have computer related vision issues grown in the past year that the Occupational Safety and Health Administration of the federal Department of Labor is considering incorporating these issues into the ergonomic guidelines that it is currently developing." Surveys cited by the American Optometric Association, an organization comprised of over 32,000 optometrists, indicates that almost 75% of computer workers have eye and vision problems. Blurred vision, along with aching, stinging eyes, is one of the most common complaints of computer use.
"Is it glare that causes the most vision related problems?"
No. Perhaps the most troubling condition is what optometrists call the "halo effect." This is the lack of sharpness, or the fuzziness, of the letters in a computer display. This condition diminishes screen readability, and forces a continuous effort by the eye to sharpen the focus of the words, which greatly increases eyestrain.
"How does glare contribute to eyestrain?"
Glare itself is the interaction of the light reflected off the monitor's tube face and the brightness produced by the monitor itself. Both light fixtures and windows often intensify glare. When exposed to glare, the eye must work harder to adjust to varying light intensities, and this leads to eye fatigue.
"Why do I have a mirror-like reflection when I look in my monitor? I have a glare-screen."
Many monitors also have an annoying condition called reflective-glare, which is the mirror-like reflection of objects positioned in front of the monitor. This makes focusing on the subject matter displayed on the monitor much harder. The Vision-Care Filter solves this problem by producing its anti-glare / contrast enhancement filters. These contrast enhancement filters reduce glare by absorbing both the inbound, as well as the reflected light as it passes through the filter. Unlike "glare-screens", the Vision-Care Filter has anti-reflective coatings on both the front and back side of its filters to eliminate reflective glare. They are also available in several different transmissions (the lightness or darkness of the glass) to provide the correct level of absorption under varying light conditions.
"Does the static charge of monitors have any effect on computer users?"
Static electricity build-up on the display screen also causes problems for a significant number of users. Static attracts particles of dust, smoke, and other airborne pollutants, causing rapid dust build-up on the screen. This condition also contributes to poor vision. Static "shocks" are not only annoying to users, but also can cause data deletion errors even at levels too low to be felt by the user.
