That’s what I paid today for an eye exam, a new lens for my existing glasses, and some prescription ray bans. Turns out my left eye is worse than my right, by a quarter of a diopter (I think that’s the way we talk about these sorts of things.) The guy assured me that I’d have 6/6 vision with these glasses… That would be 6 cent. at 6 meters. It all seemed pretty reasonable, so I went ahead and paid for everything. I probably could have gotten much less expensive frames, but these are the first ones that I actually took to right away. I have grown to like my regular glasses, but now I’ll have a set for outside.
