SofLens 66 contact lenses are 1-2 week disposable lenses designed by Bausch and Lomb to be worn as daily lenses for up to two weeks and then tossed in the trash.  Disposable contact lenses greatly reduce the buildup of calcium deposits and proteins that can bind themselves to the lens and irritate the eyes, making SofLens 66 contacts an ideal choice for the first time contact lens user.  SofLens 66 lenses are made with a visible tint to help you find your lenses in the solution.
