Genetically, I've dealt with myopia on the -2.x range most of my life till I had lasik around 20 years ago. However, now my eyes have diverged in the weirdest of ways. I have 20/20 in my right eye but can't read up close - due to being in my late 40's - and my left eye can read up close but I have around 20/80 for near-sightedness. I guess it's "good" I can handle any situation with one of the eyes but playing pool with depth perception sucks! Anyway, I have a new problem this article never mentioned. Floaters. My left eye is full of them and reading anything with these blobs blocking my vision is a game of moving my eye so it "shakes" things up so I can read where it was blocked. I have not found a therapy for it. Floaters is protein waste broken off in the eye and mine never settle to bottom of the eye. Don't take your vision for granted.
