Consequences of UV blocking contact lenses?!
Question: For chemistry class we're doing this project where we have to create new technology. I know that there are already contacts that block some UV rays, but our project is contacts that change into sunglass-like UV blocking lenses when exposed to sunlight. Similar to the transition glasses, only in contact form.
Does anybody have any ideas what the consequences of these lenses would be?
I can make up most of the positive ones, but I'm having a little trouble with the negatives.

If the lenses tint, then it will look like you have brown (or dark) eyes or it will look like your eyes are changing color. Also, if the chemical that changes color is toxic to the eye, that would obviously be bad. They do make amber-tinted lenses now for sports, but they don't change color.
