Anti-Glare screen filters

Aug 26 2008, 11:17 AM EDT

A guy emailed with a visual problem. He found that certain VDU screens gave him stinging eyes and headaches. He found that his eyes instantly began to sting when he looked at certain computers but not others. If he persisted looking at the troublesome computers, he soon developed a severe long-lasting headache and his eyes became bloodshot. By chance he discovered that those computers that were troublesome could be 'cured' by increasing the refresh rate of the VDU. All white backgrounds cause his eyes to sting instantly.

I suggested he should try an anti-glare filter or maybe a coloured overlay screen. There are varying degrees of anti-glare filtering available. The filters reduce the strain on the eyes by blocking a high % of ultraviolet rays radiated from LCD screens. In addition, the filters allow a high % of light transmission while protecting the LCD screen from degradation as a result of strong sunlight and other natural lights. I'll be interested to hear how he got on, in due course.
