Many geeks find that the world is out of focus. The world doesn't make sense. Then we get our first pair of glasses and everything shoots into focus again.

Having experienced problems with my own spectacles, or glasses as they are commonly known, has gotten me thinking that there might be a way to tweak my PC monitor to offset my myopia (shortsightedness). If it worked, there would also surely be a way to help people with hyperopia (longsightedness).

I'm not sure how you'd do it though. The picture coming from the graphics card could be put through a filter of some kind to change the offsets of the various pixels to present a coherent image to a given user. I happen to know my perscription off-hand, but if it were to become a proper piece of software, I think it would have to adjust to accomodate everyone.

There are probably more reasons why it won't work than reasons why it will like asymmetric eye strength. For 3D displays, I think it might just work though, since 3D systems are preparing 2 different images anyway.

So I put it to you my fellow denizens of this fine site. How would you do it? How would you use software to compensate or correct for human hardware discrepancies? Should we stop after sight?
