Hey doc. Well, I think I might need glasses. I’m getting headaches, and I really struggle to see things that are far away. But I have always had 20/20 vision.

Sounds like you may be far-sighted. OK, then, cover your left eye and read the chart in front of you.

Mmm. . . X, E, R, 3, a question mark, and I can’t quite make out the other symbol but I think it’s the peace sign.
a
Wow, Arthur! You’re as blind as a bat!
b
Yeah, I know, my vision is really blurry at times.

Ok then, head on over to the other room and pick out some frames while I fill out your prescription.
