I agree that mid-lower-range shops are a racket: however, don't discount the luxury and privilege of high-end options of dedicated professionals. My glasses cost in total almost $1000. I wear them almost every waking moment, they are exceptional designer hand-made frames from France with Zeiss lenses and Japanese transition technology, and the optometrist is top-of-the-line who also does an eye cancer check each year…

Every eye doctor I've been to in the last decade has done an eye cancer check, I think that's standard.

Right, that's the point: the chain stores don't have doctors, they have people who are trained to use machines and don't check for anything except getting your prescription.

Glasses are a total racket. Purchasing your glasses online is many, many times cheaper than going to Lenscrafters or basically any other brick & mortar store in the US. I've been buying online for years and they're every bit as good as usual ones. You do need your pupillary distance, but you either measure this yourself with the help of a friend, or ask your optometrist. If they refuse or tell you how evil buying gla…

I know frames are a racket but what about lenses? Are Carl Zeiss lenses really that much better than other brands?

Last time I ordered from (them or their competitor) they asked for PD (pupillary distance) is that enough or are the prescription ones still better?

Pupillary distance is basically the horizontal location of the pupils. The issue is that pupils can also have a vertical offset from the center of the lens as well. Accounting for PD alone is sufficient for some people. I'm not a doctor, so I'm not qualified to recommend one option over another. It is something you may want to ask your own doctor about though.

To be fair to Zenni, most online eyeglass sites don't request vertical measurements as the PD is sufficient for the majority of single vision users and there isn't a single vertical measurement that can be applied from one user to other glasses. Ocular center height is very subjective & measured during the fitment of that frame to the user. Optical center being the same height as geometric center is a safe choice for something only made to measure.

There are sites that take segment height for bifocals, but the intended frames need to be in hand for the user to measure.

I also do this. I used optical4less and highly recommend it. I got high quality mineral glass lenses and they were great. Can't go back to polycarbonate after those.

I get mine in Japan, e.g. from Jins. That's brick-and-mortar: personal service, ready in 30 minutes. Around 8000 yen, frames and lenses.

> I have a fool-proof way to do this yourself. Use a mirror and a ruler. Place the ruler on the mirror and stare with your left eye into that same eye's mirror image, such that the ruler's 0 tick is centered on the pupil. Then, open your right eye and close the left. Stare into your right eye across the ruler and note the millimeters. Flip back to the left eye to make sure you haven't moved from zero. Damn, that's re…

It's easy to come up with in the course of experimenting to measure your own inter-pupillary distance.

It goes without saying you will need to look at yourself in a mirror, with a ruler somehow. From the parallax problem is obvious, as is the fact that it's only a problem for mismatched eyes.

So you're saying that the glasses from all these places are cheap/poor quality? That is disappointing.

If you're total price shopping, yes. If you want a specific frame for some reason, it's a good value. I bought a pair of Oakleys from glasses.com ( a luxottica online outlet) for a savings of about $50 from retail. I think the high index lenses were cheaper too. But if you buy $8 glasses, they are going to be junk.

AFAIK almost all the glasses frames are worth few dollars. What you pay for branded ones is marketing and bit of design, not generally the material quality.

Warby Parker ( https://www.warbyparker.com/ ) makes some really nice "luxury" glasses, even though they still cost less than the cheapest pair you'll see in a typical store. They'll even send you 5 frames to try on at your home.

warby parker frames look trendy but they're pretty low quality cheap plastic frames, and they're dramatically overpriced compared to comparable glasses from zenni or similar

Anecdata, but my SO and I both have had frames from them for about a year with no issues, and my mom's had hers for about 6 months and had to bend them quite a bit to fit her and they've been just fine.
