I doubt it - my vision is worse than that of my brothers because I've been standing in front of computer and reading math books too much in the past.

A golden advice from an eye-doctor that makes my eyes much less tired (ymmv) even though I don't strictly adhere to it: every once in a while (~30min) rest your eyes by just looking at something about 15ft away or by keeping them closed for about 1 minute. Don't necessarily try to focus on something far, just look at it.




Unless you and your brother are clones of each other, you have different genetics.

Even identical twins have different genes.
