The worst thing is they are just relying on you to tell them what works.
“Can you read this? Is this better? How about this? A or B?”

There are now machines (Autorefractor) that will (more!) accurately get your prescription auto-magically. A couple of years ago I went to place that had one, but where the doctor also checked the traditional way. The results were the identical.
I’d guess that inside of 10 years you will just get your prescription by computer and that inside of 25 surgery or other solutions will be automated and permanent. This industry of charlatans will be no more.
