I just got back from the eye doctor because I was having pretty severe eyeaches, especially after using the computer. I had glasses previously for reading, although barely used them. Since they were prescribed, each of my eyes' prescription went from .75 (L), .75 (R) to 1.25 (L), 1.00 (R). I got to pick new glass frames and everything. The optometrist said that I have Hyperopia of farsightedness, so basically it takes my eyes longer to focus on close objects, which can strain my eyes, even though I have a very small prescripiton. My left eye is worst than my right! Hopefully this is the reason to my whopping eyeaches.
