ALL of my friends and most of the people I knew had contacts in highschool, except myself and one other girl and 3 guys.
I graduated HS 14 years ago, and the school had over 500 kids and I STILL REMEMBER exact numbers. One of the things I did when I "ran away to join the circus" (aka enlisted in the military at 17) was to take off my glasses and back over them with the mini-van the day I took myself to the airport for bootcamp. LOL... as a matter of fact, while I was Rx'd "BCGs" (birth control glasses) in bootcamp, I wore my contacts every day except for gas-chamber day. And have ever since. I keep thinking I need to get a pair of glasses in case of emergency, but it took me 10 years to even consider the idea, the "glasses-war" had been so heated.
GOD I hated those glasses.
Of course, they weren't the reason I left, but only one reason amongst hundreds of examples of how my parents didn't trust or allow me to make any decisions on my own. It didn't matter how strongly I felt about something. On a side note... home on leave with my contacts in, people literally didn't recognize me. And I got the "Whoa... you're, like, pretty." comment so often it made me realize that teen boys are pretty STUPID and it's probably better I didn't date any of them after all.
And... as you say... now many children are getting them (and doing WELL with them!) in gradeschool. Contacts have come a *long* way from the ones in the 70's & 80's. Even the 90's. You don't even have to clean them anymore if you get dailywear or extended wear disposables. And many allow nearly as much o2 to the cornea as going without
So while I'm *obviously* biased... i say "go for it" or get a new doctor.
