CIBA Vision's O2 Optix contact lenses are 1-2 week disposable lenses designed to be worn as daily lenses for up to two weeks and discarded. Because they are routinely replaced, O2 Optix lenses ensure that your eyes will not suffer irritation from deposits built up on the lenses. For superior comfort, O2 Optix contacts allow up to five times the amount of oxygen than do other brands of soft contact lenses. For ease of use, O2 Optix lenses are made with a light blue handling tint to assist you in locating your lenses in the solution.
Lens Material
O2 Optix (lotrafilcon B) soft contact lenses are made from a lens material that is approximately 33% water and 67% lotrafilcon B, a silicone containing hydrogel which is surface treated.
