Short answer, no. Long answer, kinda? When you first get them, it takes time to get accustom to wearing them. During that time, your eyes will encounter some irritation, but not pain. The temporary irritation is well worth the benefits.
Because they have a hard time adjusting because if you wear your contacts more than don't and u take them out one day it will be more blurry for about 30mins so it can adjust and it might hurt
Yes, wearing contacts that aren't yours can severely damage your eyes. Be sure to get contacts that are right for your eyes.
You have to make sure they are clean throughly
I'm 12 and I wear contacts they don't hurt at all it might feel like you have something in your eye for a while but it goes away after you blink a couple times. But the ones to just change your eye color burn if you don't know how to use them or handle them properly.
Not at all, but they are slightly annoying at first
Maybe because You had ur contacts on for more then 12 hrs.. another can be if you pay attention to your eyes too much
Yes they hurt alot the first few times. Once you get used to them it's not so bad.
Mercury
Yes of course you can
Yes it will hurt more when i t is hard.
Yes, it does hurt very much.
It could hurt if you pulled it out hard. But if you wiggle it everyday, it would not hurt then.
