contact lens

Do you wear contact lens? I don't wear it. I want to get it. Contact lens is very useful because we don't need to wear the glass. We can do everything without minding our glass. But to wear contact lense has high lisk for our eyes. Lens touches to cornea directly, so cornea tends to be injured anytime. And our life is apt to be irregular, so maybe someone forget to put off his contact. That's very dangerous!! If you are using contact lens, please use right way.
