A 2004 cross-sectional study in 9124 Japanese workers indicated that there was a possible association between heavy computer users and glaucoma visual field abnormalities. In other words – if you use computers heavily, ie, programers, software engineers, gamers,
The study looked at typical daily computer use, as well as long-term computer use history. More than 500 participants (5.4%) had problems with their peripheral vision. Of that group, one third were found to have glaucoma … perhaps more than a third, since some workers with peripheral vision problems didn’t receive all the testing to accurately diagnose glaucoma.
Even more significant was that heavy computer users who were farsighted or nearsighted seemed to have a higher risk. Nearsightedness was found in 82% of those with glaucoma.
