Hank @jesfactsmon, not a dumb question at all. I can speak for myself with my experience using an eye patch. After a few months into my AVM, my neuro ophthalmologist told me I could either wear an eye patch, cover up the glass lens with frosty tape, or wear clear glasses while my eyes settled. It didn’t matter because there was no sufficient data to prove what was best. It was unknown how much the eyes would correct themselves during the healing time. I decided to use the black eye patch. After using it a month, I tried to see with both eyes but the image of the previously covered eye was very dark. It remained that way. It was very bothersome so I never used the patch again. I then tried covering the glass lens with frosty tape. It allowed the light in while eliminating the double vision. Thankfully, the dark image eventually went away. I used the frosty tape for a couple months until my next eye visit. When my ophthalmologist examined my eyes and said, “let’s see how your eyes adjusted”, I thought how would they adjust when my eye was covered? I was told to give it longer for my eyes to settle. As soon as I got home I removed the frosty tape and only wore the glasses. After a while I went back to the frosty tape because the double vision became too much for me. I was fine for a while until the eye dryness and photophobia kicked in.
Good idea to wear a patch but my eye got used to the darkness.
