Hey, 4-Eyes!

So why is such a large portion of the population born with defective eye balls anyway?

Seriously, you'd think evolution would fix this at some point but yeah, why do SOOOOO many people need glasses? And in particular, asians.

Most people aren't born with bad eyes, they just do things to make them worse. Why do you think "nerds" tend to wear glasses more often than normal people? Because they spend more time in front of computer screens while in dark rooms. Such bright light isn't natural or good for one's eyes.
