I've found that my eyes are affected from spending too much time looking at stock charts and such on computer monitors. Over the last few years I've had to get stronger and stronger prescriptions. Finally my prescriptions for distance vision became so strong I wasn't able to see my computer monitor. The optometrist said I need bifocals. I bought a pair of glasses with progressive lenses which I absolutely hated. I could hardly see to drive except in one small area in the top of the lense. If I wanted to see my computer monitor I had to cock my head up and look at the monitor from about 12 inches away. I did some research on the net and found claims that eye exercises can cure myopia. Basically the proponents of eye exercise are claiming that the whole system of optometry and opthamology is a scam. Here's one of many articles describing the theory in detail: http://www.odemagazine.com/doc/3/free_your_eyes/ I'd love to be able to improve my vision and avoid having to get stronger and stronger prescriptions. Has anyone else experienced deteriorating eyesight from too much time looking at the computer? Has anyone tried any form of vision therapy or do they know anything about it?
