But im afriad they may not be safe, i ordered hem and their not here yet then i started reading articles over all the injurys. Their not prescription ones but they are fda approved. Im worried ill hurt my vision, but i dont wanna return it cause i had my parens pay 30 bucks for it snd they will get angery if i change my mind.
