These are incredible. I was recommended at Warby Parker (since they didn’t do same-day) to visit them when I was visiting San Francisco, and was in the need of a new pair of glasses.

I had an eye test onsite, picked frames, and picked up glasses all within 75 minutes. Awesome experience! I think they are off Powell and O’Farrell, and I’m wearing them right now.

I second this recommendation. The JINS experience (at least in Japan) is amazingly convenient, pleasant, and affordable. I sometimes drop in to pick up an extra copy or two of a pair that I like, and get my current pair tuned up. They'll keep your lenses in their system so you can drop into any store. Thirty or so minutes in and out, and exemplary customer service. What more can anyone ask for?

They have free shipping. Hi-index single vision lenses are included in frame prices, https://www.jins.com.

JINS PC (blue-light blocking) glasses were an industry marketing breakthrough, selling almost 1 million units in the first year, https://corp.jins.com/jp/en/company/history. Their success prompted eyeglass lens makers to launch blue-blocking coatings, now widely available.

Can anyone shed some light on whether blue-blocking coatings are actually useful/good for you?

A HN comment set me looking for some blue-blockers for night driving: https://news.ycombinator.com/item?id=14170975

My locally-owned sunglass shop stocks yellow blue blocker safety goggles that fit over my glasses. They turn obnoxious blue headlights green. I give them a 'blue headlight obnoxiousness reduction factor' of 85%.

The orange safety goggles ("uvex") I ordered from Amazon first were better (95%), but they block out too much green to be safe for night driving.

For computers, Flux (http://justgetflux.com) offers more control of blue light, and it does make a difference. Also, increase your blinking, periodically focus on distant objects (use a timer if needed) and don’t look at a bright screen in a dark room without ambient light.

South Korea as well, I got a paid of glasses made in 20 minutes as I walked around and ate street food

To add to this, I have a strong prescription requiring kinda special lenses to not be crazy thick, and even with that I got a really expensive frame with the special treatment for ~$150.

In France, the "not 2-inch thick" lenses alone end up costing that, with me ending up paying over $300 + the habitual 2 month waiting period just to go to the optometrist...

So even if you have some special needs, they'll often be able to accommodate (though sometimes you need to wait a day so it won't be same day)

I came into the comments to mention JINS, and ask why a competitor with their business model can't start up in US?

JINS actually starts at $50 (price includes eye exam+frames+lenses, and you can drop by whenever afterwards to have them cleaned/adjusted), and when I had mine made it only took one hour. I saw the machines they have in the back that prepare the lenses on-the-spot. In effect lens 3D printers. Neat stuff.

You’ll get premium eyewear in India for $150. Though, it will take around 3-5 days to get it after your order. Good quality ones that last would be $60-80.

Any idea how long has this been possible in Japan and Taiwan?

I remember around 15 years ago in Bangkok my friend broke his glasses so went to the first opticians he found in a mall. He didn't have his prescription so they took some eye tests, he then picked out his frames and lenses and then was asked to return later that day for pickup. Absolutely blew our minds that this was possible

I got some glasses made up for me on my last trip to Malaysia. Cost less than $50 all up.

Me too - the whole family actually, cost around $50 for great lenses service and frame.

$32USD complete pair. 100+ frames to choose from, done within a few hours or shipped to your door for $3.

I bought many over the last 5 years.

If you are in LA, there are some JINS stores too.
