I'm wearing contact lenses. I really appreciate the useful invention. I don't like to wear glasses… The lenses are very nice but I have to take a small container with special liquid with me all the time. So, in the evening its necessary to take the lenses off. It's very big problem if you have no container! It's impossible to improve my poor eyesight… And I wish to wear contact lenses all the year round. Maybe it is possible to implant the lens into the eye?
