Eventually, yes. But your optometrist does more than just check your refractive correction, but it’s likely nothing that a couple of pictures, a short video and some AI can’t muddle through with a pretty high precision.

Getting your refractive index would allow them to at least order your glasses. And they could always send off your imagery to a service that looks at the data. Hell, if you’re a contact wearer, they could probably just dispense them from the machine.

The one thing that would still be missing is a place to actually properly fit you, and then fix your frames after you’ve settled them a few times.
