Phoropter
I went to the eye doctor today. All seems well and I did very well on the peripheral vision test. He said he doesn’t see a lot of perfect scores but I got one with one eye and only missed one dot with the other, so that’s good news. He’s following two issues but said that neither is causing any problem and I don’t need to come more than once a year. While I was waiting, though I took this picture of the phoropter, although he didn’t actually use it this visit. My eye sight hasn’t really changed since I got my glasses.
