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

A: Wow, Arthur! You're as blind as a bat.
B: Yeah, I know my vision is really blurry at times.
A: Okay, then, head on over to the other room and pick out some frames while I fill out your prescription.
B: Thanks, doctor!
