Americans know that eye health is important, but many don't make taking care of their eyes a priority. That's according to the American Eye-Q survey, which found that when it comes to knowledge of contact lens hygiene and eye diseases, Americans are lacking. For instance, 79% of respondents reported wearing daily contacts overnight, and more than 1/2 of those who participated didn't know that an eye exam can screen for many different diseases.
