My eyesight is pretty bad too. I don't believe the computers are a direct culprit, but they might be indirectly and partially responsible. Staring to the screen usually causes nothing more than eye strain, which may indeed result in vision problems, but those are reversible - sufficient rest, frequent brakes, some exercises, and it should be back to normal. However, as it turns out, I have a rare genetic condition which makes my eyes unusually weak and incapable of repairing damage. The combination of staring at the screen combined with horrible air conditioners in the office caused my eyes to dry out and burn like hell, which in turn caused massive death of cells that couldn't repair themselves due to the above deficiency, damaging my eyesight. Hope that clarifies things a bit.
