I've had contacts for 5 years now, since I was 12. I had the same problem. Your eyes are probably just not used to having contacts in them yet. Just give it time, you'll get used to them. Until then, I agree with BabyPiglet.......use eyedrops, they really do relieve dry eyes! But if they're really bothering you, definitely take them out. Especially if you're at home, where no one will see you anyway. It will take your eyes time to be able to wear contacts for long periods of time. Besides, you will have to wear your glasses once in a while when you're having contact problems!
