I can read the letter E on the chart. I know from memorization that the next few letters are F, P, T, O and Z. I don’t know if I can actually read the third row and down.
If I wear glasses often, which I have been doing for the past 2.5 years or so, my vision is a little blurry without them.
I’ve always had great vision, but wearing glasses makes it worse. I got the glasses so I could do a 10 hour drive without stopping (and for reading for extended periods) because if I stare at something for more than a few hours, my vision goes blurry.
For some reason afterwards, I continued to wear them. Now, if I don’t put them on my vision isn’t as good. It’s. . .weird.
If I go a few days without depending on them, my vision will be fine again.
The last time the doctor told me what my vision was in terms of 20/x was when I was a teenager (I’m 23 now), and back then it was already 20/400, and I’ve gotten a couple new prescriptions since then. 20/450, 20/500? My guess is somewhere along those lines.
Basically, without glasses or contacts I can only see by contrast. If someone puts giant white letters on a black wall 10 feet from me, I might be able to make them out, but if someone asks how many fingers he’s holding up but puts his other hand behind that hand so I can’t find a color contrast, then even if it’s a couple feet away I won’t be able to make it out.
