How do contacts lenses stay in your eye, and what if it got lost behind it?
Friday, October 2nd, 2009Sometimes my contacts move upward in my eyes when i close them because I have toric lenses. What if i kept them closed and shut them for a long time and real hard. If they went out of the front, what would happen to them? And what makes them stay in place anyway?
They mainly stay on the eye due to surface tension. Toric lenses are weighted and shaped in such a way to where your axis will be automatically aligned to where your cylinder power is in the correct place.
They cannot get lost behind the eye since the eye is actually a part of the socket. The space you see by pulling out your eyelids is all there is. The worst that could happen in this regard would be if they folded and lodged behind the eyelids.
As others have pointed out, you are not to sleep in your contacts unless they are made for extended wear.
