Nearsightedness on the rise

Jim Ray has an interesting thought on nearsightedness (which has increased by 66% over the last 40 years):

This also strikes me as one of those fairly obvious cases of humans actively working against our own evolution. Nearsightedness isn’t being bred out because it’s relatively easy to fix — a pair of glasses or contacts. Even worse, the fix just might be working against evolution in that, at least to some, a pair of glasses is a desirable trait (how else to explain their hipster cachet?). Contacts and even lasik only complicate things further since they fix the symptom but not any root genetic causes without providing any kind of flag to potential mates that your children are going to need an opthamologist.

He also notes, obviously, that the numerous glowing rectangles that we now center our lives around don't help. I've never worn contacts or glasses, but one of these days I know my eyes are just going to blow out.
