I wore contacts for about 15 years before I got lasik in 2000. I can tell you that with contacts your vision will keep getting worse because the doctors will do the same thing they do with your glasses...keep pushing stronger and stronger prescriptions. My vision was 20/700 by the time i got lasik. (20/200 is considered legally blind, so i was way past that) I couldnt count fingers at 3 feet and I couldnt even see the big E on the eye chart(it looked blank to me) Anyway back to contacts...Here are the problems I remember.
First I started with daily wear. When I first started, it sometimes took up to 45 minutes to put the contacts in my eyes. (sometimes they fold in half when going into your eye and you have to take them out and retry) Then it took a while for my eyes to get used to it so I could only wear for a few hours per day starting off. Once I got used to it I could wear them from morning to bedtime. Probably at least once per month the wind would blow my contact out, or i would blink wrong and it would fold in my eye and it would be really painful. When your eyes itch with contacts, you cant rub them or they will fold and cause you pain...you have to "massage" the itch instead. Also..you spend alot of money on contacts and the equipment that goes with contacts. If you accidentally sleep in them, you will have a hard time getting them out the next day(if they are daily wear) If you get extended wear, disposable contacts, then you dont have to buy all the contact stuff that you buy with daily wear, but they say you are supposed to throw the contact away after 2 weeks, so that can actually get more expensive.
Also you can get certain eye infections from contact lenses because the lens goes on your finger before it goes in your eye.
Ok...now that all the bad stuff is out of the way...here is the good stuff.
First...nobody will call you 4-eyes if you wear contacts.
hmm...thats about it.
Oh here is one you might like. When I was 17 I got these really green colored contacts and wore them for 2 years. Pretty girls would stop me everyday and tell me how beautiful my eyes were and I do mean EVERY day. I still remember one day just walking down the street minding my own business when a young 20 year old woman said "wow i love your eyes" and as I kept walking she yelled louder "Can I have your baby?" Can't say women will still do this though because when I did it, it was the early 1990s and people had not really seen colored contacts yet, so that ship might have sailed for you.
I should mention that if you have brown eyes, colored contacts look very fake and will make you look like a crazed alien if someone is really close to your face.

Colored contacts only look real if you have blue or grey eyes naturally.
