I am 12 and are getting contacts so yes I think they are just fine. Glasses aren't a problem but if he is irresponsible you should start out by checking to make sure he wore them. I personally think that anyone over 11 is fine to wear contacs. My aunt is an eye doctor and she says 10 and up. Contacts may be hard to put in at first but soon it gets very easy. Hope this helped!
yeah i love wearing them makes playing sports easier then you won't be blind or have to wear those special sports glasses plus that means that whenever yu don't feel like putting them in you can just wear your glasses. FYI thanks for following me!!
