Found the piece of paper my vision Rx is written on:

OD (right eye): -400+200X113
OS (left eye): -375+250X070

Okay. So near as I can tell: in my right my nearsightedness is four diopters, and my hyperopic astigmatism is two diopters, at 113 degrees. In my left eye, my nearsightedness is 3.75 diopters and my hyperopic astigmatism is 2.5 diopters, at 70 degrees.

Apparently if my astigmatism is worse than two diopters, the correction I'm going to get with surgery is rather unlikely to be perfect.

This doesn't explain why my right eye is the one that sees worse with my contacts. Also, the base curvature of my corneas is 7.5. Which is, according to the eye people at work, pretty damn curvy. Hence the problems I had with soft torics.

Blargh.

Heh. Now I'm curious what everyone else's Rxs are. Post'em if you got'em.

I just looked up the definition for "hyperopic," and I think I must be reading the Rx wrong. In hyperopic astigmatism, if I'm looking at a grid/tic-tac-toe board, etc; the horizontal ones would be clearer. But I see the vertical ones more clearly. WTF?

interestingly, my vision is better than 20:10 when properly corrected - with a new set of contacts i have super-uber-vision.

With my glasses I'm 20/15, and I've had these glasses for over two years.

Supposedly RGP's (the hard lenses) will give better vision than soft lenses. That's so depressing. :^P Hard lenses suck.

I don't think RGP's suck, but I've had them since I was 7. And glasses since I was 5.
