I seem to get better results, but I still have quite a few misses too.


Oh and I am nearsighted w/ +1.75 reading glasses. Is there a diopter I can buy that is +1.75?


I ask because I just picked up the 100mm 2.8 macro (not the L version).

I am by no means a doctor, but I don't think reading glass prescriptions translate to nearsightedness. Looking on Wikipedia, it seems that reading glasses are for hyperopia (farsightedness) and/or presbyopia (inability to focus on objects close to the eye). Might want to ask your eye doctor about photography and how it applies to your glasses choices.
