A year and a half ago, when I weighed 220 pounds, I noticed that it was becoming hard to see the board at school (in a big lecture hall, but still). I got very low perscription classes that clarified the writing, which had become blurry.
Yesterday, being down below the 30 pounds lost mark, I put on my glasses in class, and noticed things didn't seem to be any sharper. I tried looking at various things around the room and outside with glasses on and off, and I think my vision is now 20/20 again.
Is this a typical side-effect of weight loss? Either way, I'm pretty thrilled. I didn't much like the way the glasses looked on my face.
