My boyfriend bought his last pair of glasses from go-optic.com, and the experience has been a good one. First time online buy as well. Some caveats: * We picked the frames from a physical store first and didn't buy there. Sort of dodgy of us, but their prices were insane. * We tried to do the pupil measurement on our own, but every time we tried, we got a different number. So he went to a optical shop to have the measurement done. The shop did it for free and we were taking advantage of the brick and mortar presence. So yes, appears to be completely doable but I don't think we would have been happy with the final product had we not had access to a local shop.

For pupillary distance, optometrist typically do it for an extra 5$, but an easy way to do it is to hold a ruler with clear mm marks on it beside your head level with your eyes and have somebody take a picture, then measure the distance with a compass.

  We tried this, watched all the how-to videos, etc. I just couldn't take a reproducible measurement. We tried maybe 6-8 measurement attempts, and the results were all different. At this point, I gave up. Of course I was doing something wrong. Without a repeated measurement I didn't have confidence to base an expensive purchase on my work.

    If you try taking a PD measurement at multiple brick & mortar stores, you may be surprised at the variation. Prior thread: https://news.ycombinator.com/item?id=15154066 https://news.ycombinator.com/item?id=15154066

    Three factors play in: - where the subject is looking. Make sure they are looking at leat 4 or 5 meters out, not at you taking the picture! Your pupils get slightly closer and further depending where you look - where the ruler is. Make sure it is at the same level as your eyes, in terms of distance from the back/front of your head. Make sure the ruler is as close to 90 degrees to the nose as possible, as parallel to the eyes as possible - make sure the camera is as parallel to the ruler as possible Also I find printing out one of the pic (just b&w on a regular laser printer) can be easier to measure, as opposed to do it on a screen.
