I wear a lot of eye makeup, and it is hard on my contacts. I have gone to the optometrist and gotten brand new contacts and when she looked at them there was already protein buildup. My lenses were only staying clear and comfortable for a few days after opening them. She recommended clear care and gave me all the warnings about not putting it straight into your eyes. If you read the box and use it correctly, this solution does the trick. My contacts now stay clear and comfortable for three or more weeks. It gets the makeup off of them and the feel new every day. If you aren't using it correctly though, it's bad. I have messed up a couple times and it is just like lighting your eye on fire. But as long as you rinse with water and wear glasses for the rest of the day it is no problem. Just have a backup pair of contacts and follow the instructions and you should be fine. Even after scorching my eyes with it like five times now, I haven't changed solutions, it is that good.
