I wanna buy rimless prescription glasses from the online shops, my colleague said the polycarbonate eyeglasses lenses are suitable for rimless frames. Is he right? If yes, Why polycarbonate eyeglasses lenses are suitable for rimless frames?

Yes, your colleague is right, the polycarbonate eyeglasses lenses are suitable for rimless frames as they are very impact-resistant and thinner than regular plastic lenses.

many people like wearing the contact lenses, especially the black color, this kind of eyeglasses could make your eye looked big and beautiful, I agree with you. But don't wear contact lenses to sleep,contact lenses should be replaced periodically, periodic review, strictly according to the description and check with the instructions to impart division wearing and nursing care.
