That is some good information. My wife and I both recently had a bad experience with an optometrist. I call it Fast Food Optometry because the building was once a fast food restaurant and he took less than 10 minutes to examine us. Even WalMart took longer than that. On top of that, he gave me a contact lens that was underprescribed. Here are my 2 prescriptions I got from them. FastFoodOptometry: R SPH -2.50 CYL -0.50 AXIS 20 L SPH -3.50 WalMart: R SPH -2.00 CYL -0.75 AXIS 67 L SPH -3.25 CYL -0.25 AXIS 130 Before I got the second opinion at WalMart, I had a pair of glasses made and for the most part, they seem to be OK, but I do see some occasional double vision in my left eye, which may be caused by not taking the astigmatism into account. I see a little of that in my right eye, but not often and not much. Could be from degrees being off or the powers being slightly different. I'm having a pair of glasses made using the WalMart prescription, but they haven't shown up yet. I'm getting them for less than $40, it's nice we have the option of online so we can afford to do this. Two nice looking pairs of glasses with all coatings for under $100 isn't a bad deal at all. Based on what you say, these prescriptions might be indentical or nearly so. I'll have to post once the glasses come in. RedStickHam -- Check us out at the oft-updated http://glassyeyes.blogspot.com!
