How can we convince them to let us protect our eyes?

webMd. com is a really good website; they should be able to give you some tips. You could also go to justask.com, where they have really good advice (I would recommend this website, because the website utilizes real professionals, not just facts that you see on a computer screen.) the only downside to justask.com is that there is a small fee for every question you ask, but the advice they give you is more than worth what you pay. (and you only pay the fee if you like the answer they give you; so if they give you an answer, and you are dissatisifed, then you don't have to pay anything. You can also choose the amount you want to pay, which is really good.)
