Worse yet it's going to make glasses even more expensive.
For those not in the know, EssilorLuxottica is basically the monopoly for everything glasses related. They're the reason you spend hundreds of dollars on 2 cents of plastic for a frame, and why mass produced optical lenses cost hundreds of dollars each.
And they own the vast majority of stores that sell glasses - from the ones your optometrist sells (about 100% of them), to several huge chains like LensCrafters. Its basically a worldwide monopoly.
Sure, you can save by going to independent stores, of which there are a few chains, but they are much more limited in their offerings.
Glasses frames are just cheap pieces of injection molded plastic, or a few dollars worth of metal. They hold a lens. There's nothing high-tech about any of it, yet they cost hundreds of dollars apiece. More if you want them molded with some designer's name on it.
LIkewise, the lenses come from well known lens manufacturers - Nikon, Canon, Zeiss, etc., who make them by the millions, likely their main source of income over say, camera or projector lenses. There's no reason what is effectively a cheap piece of optical plastic coated with well known coatings (anti reflective, etc) should also cost hundreds of dollars. They don't require the precision assembly of a multi-stage camera lens which cost about the same amount of money. It's just a lens.
Granted, someone needs to cut the lens to fit the frame, but even that's generally machine controlled - the machine finds the optical center and using the lens template (the fake lens in the frame) and your prescription cuts the lens as needed. A process which may be done on site, or automated at some factory.
So yeah, it's concerning because the world doesn't need more expensive glasses. It's a pure profit item likely rivalling margins of popcorn and soda at movie theatres.
