There's a part of me that says it can be a bit silly and... "hipsterish" but, overall I think it's fine (and cool for the right type of person)
I admit I want to wear them; Oddly, people assume I wear glasses. They imagine me wearing glasses. An old friend will ask where my glasses are if I haven't seen him in a while (and yes, they're disappointed because "I looked SO GOOD in them!" When I haven't worn glasses; I just embody the personality of the smart geek with the glasses, I guess. It's odd how much it becomes an issue with people suddenly noticing I don't wear glasses (That I don't wear); they're freaked out. It happens a lot.
I admit, though, I'd feel silly about buying them; like buying them non prescription would seem weird, though IT HAS to be more common than you'd think. I just feel embarrassed about trying to get them when I don't need them. Like getting a wheel chair when I can easily walk.
I see this as not much difference from girls wearing heels to look taller; and yet if guys do it, it's "ridiculous" and "fake." Girls don't think twice about extensions, wigs, false eye lashes, water bras - pushup bras, spanx, girdles, makeup, etc. Why can't guys do something to help them look better?
I'm an aspiring actor though, so I'm fascinated with stuff that people assume about someone based on looks. Drew Carrey supposedly had Lasik surgery done about a decade ago; and he wears his old glasses, because he found going without was bad for his 'character.' People were too used to "Drew Carrey wearing REAL glasses" and when he stopped, no one recognized him. So he started wearing glasses again. It had become HIM. He's stuck with them for a while.
I'd ay that if it makes you look good, fits your 'character', and makes you more confident (without being a crutch), then go right ahead. Don't worry about the haters.
