Every year I curse the optometry racket when I run out of contact lenses and have to return to the optometrist to get a “new” prescription. It’s a service that I don’t want and don’t need but am forced to buy by US law which require patients to have a recent doctor’s prescription to buy eyewear. I can stretch out the time by buying months in advance, sometimes I buy when abroad, for a few years I managed to evade the law by buying from Canadian internet sellers but that route has mostly been shut down. Writing in the Atlantic Yascha Mounk notes that around the world no prescription is needed:

If you already know your strength, you can just tell them what you want. You can also buy contact lenses from the closest drugstore without having to talk to a single soul—no doctor’s prescription necessary.

The excuse for the law is that eye exams can discover other problems. Sure, trade offs are everywhere. Let people make their own decisions. as Mounk concludes:
