I haven't had glasses since 1997.
First out of choice (my glasses were HIDEOUS... I picked then out when I was 10, with a 10 year olds fashion sense - Hint: I'd just seen medicine man... We're talking big honkin glasses in the 80s style of aviator HUGE), and we didn't have enough money to replace them, so I wore them until I was 17, joined the military, and got contacts. I backed over them with a car. Sigh. It didn't really damage them that much.
I wore contacts on the sly in boot camp, the BCGs were almost as unattractive as my last pair (military issue glasses are nicknamed BCGs as 'birth control glasses'), and like most others in my platoon my BCGs mysteriously disappeared after a couple weeks ;)
I've WANTED glasses again for about 10 years. But at $800 for a cute pair, or even 200 for a cheap pair it just wasn't gonna happen.
I've wanted them for 'backup'. In the past 15 years I've worn my contacts 24/7... Only taking them out to put in new ones. I have SUPER healthy eyes, but I've had pinkeye twice, 1 serious infection, & gotten hot peppers in too manin them too many times to count. I've ripped my last lens. I've gotten sand in my eye. I've worked in Chem labs, and done a hundred other things that a pair of glasses would just be USEFUL.
My eyes love contacts. I sleep in them (not everyone can), never get dry eye. A majority of people take them out at night. Glasses take 1 second to put on in the morning. 30 seconds to wash your hands and put in contacts might bunt seem like a lot UNTIL you've got a sick kid or someone knocking at the door! (Or god forbid a fire or medical emergency). People who don't sleep in their lenses HAVE to have glasses. People who get dry / scratchy eyes from their lenses would go insane if they couldn't take them out!!!
Oy. I'm apparently in a never 1 word when 50 will do phase. :P I'm sure you got the point 8 pages ago!!!

HINT: Don't pick out frames until AFTER your contacts. Seeing clearly changes how glasses look on you! (part of my mistake in 1990)... But I've also come close to buying several times. They ALWAYS look different after you can see again!

(Oy. More words)
Remember it takes 3 days for your brain to adjust to your vision changing. The clarity should be immediate but there are some side effects (like seeing the lens move on your eye, feeling "thick", etc.) which are HIGHLY ANNOYING if you're super sensory. But that all goes away in 3 days.
Cool study... some neurologists had college students wear goggles that flipped their vision upside down. In 3 days, they woke up and everything was "right side up". Then the neurologists had them take OFF the goggles. You guessed it... everything was upside down! 3 days later, their brains fixed the issue. (Bet those researchers broke out in a cold sweat waiting! Not to mention the kids!)
A lot of people are so annoyed by the way contacts feel on day 1 that they take them out. And then only wear them a few hours a day, or occasionally. If you do that they will ALWAYS be annoying. If you can stand the Arrrgh! factor for 3 days, though, then it feels like you aren't wearing anything in your eye. No floating, shaking, thick feelings, etc. Some people or 'work their way up to' a whole day over several weeks. No worries there. Just means several weeks of being annoyed in smaller increments until they're worn for 3 days straight.
