huh. the biggest problem I have with buying glasses online is the lenses. The PD (I believe is what it's called; the distance between your pupil and the bridge of your nose) is super important for the glasses to work very well at all.<p>Yeah, you can fuck around with a mirror and a ruler, or once at wallmart the kid at the counter just looked at me real hard and drew spots on the plastic filler lens... as far as I can tell, the actual machine to do that measurement? makes a pretty big difference.<p>I think the optometrists know this, too; the optometrist is happy to give me my prescription, but they won't give me the PD numbers. "you usually have it measured when you get the frames" they say. (I should look if it changes.)<p>And that's the thing, the difference between pretty good glasses and perfect glasses is huge for me. Enough that I'm happy to pay five hundred bucks for a product I can get for fifty online.<p>That said, my local Cosco has those machines, and as far as I can tell, the lenses they grind are just fine, and if not 1/10th the cost, at least 1/5th the cost of the optometrist.<p>But yeah, until they solve that measurement problem? I don't really see how this is any different from any of the millions of other online frame/lens retailers, save for the vertical integration (which is kinda interesting.)
