Hi everyone, I just got home from LensCrafters with my fancy new $443 glasses; the bad news is, I can't see properly out of them, for multiple reasons. I normally wear contacts, and the glasses are for "backup" but need to be good enough for wearing multiple days per week to rest my eyes from the contacts.
So, I did the research that I should have done before I went to LensCrafters, and it seems maybe I got screwed (but I can back out with a 100% refund within 30 days). I think that online glasses might be for me, so this post is to help me figure out what to do next. I also have a pair of old glasses, which I believe were also purchased at a chain and have basic plastic lenses (I assume CR-39) with no anti- reflective coating. I'd like to replace these. My prescription is -2.50 plus cyl -0.75 70 in one eye and -4.25 plus cyl -0.25 180 in the other. What I like about my old glasses: * Very little chromatic abberation (color fringing). * Consistent correction across the frame -- it's sharp all the way to the edge of the lens. What I don't like about my old glasses: * Distortion is bothersome at times. * They give me a headache after several hours of wear. What I like about the new glasses: * Less distortion than the old ones. * Sharper than the old ones, when they're sharp. What I don't like about the new glasses (Featherwate Complete polycarbonate) * They're only sharp at near/middle distances. * Heavy chromatic abberation -- e.g., it's distracting for reading. Only in the very center of the frame is there no visible abberation. * Correction is very inconsistent across the frame -- only in the very center is it really sharp. So, they're going back. The online research seems to indicate that what I want is very basic: CR-39 lenses, low refractive index, with anti-reflective coating. Where can I get this? And how do I know what I'm getting? Of the vendors mentioned on the blog, 39dollareyeglasses smells the best to me, but they don't seem to offer plain single-vision CR-39, just in sunglasses or bifocals. Goggles4u offers CR-39 but in a refractive index of 1.56, which seems to have an Abbe number not much better than polycarbonate. Sorry about the length. Any advice would be much appreciated!
