Do Acuvue 2 Colours - Enhancers Block UV?

I heard that Acuvue 2 Colours contact lenses help to block ultraviolet rays from your eyes. Does anyone know if this is really true? Do they work like sunglasses?

Here is some detailed information on that:

These lenses block about 96% of UV-rays and 99% of UV-B rays
They greatly reduce harmful UV radiation transmitting to the corneal surface and into the eye. One thing to remember is: UV-absorbing contact lenses are not a substitute for protective UV eyewear such as UV-absorbing sunglasses or goggles because they do not totaly cover the eye and general area. You should still use UV-absorbing eyewear as directed. Warning: Lengthy exposure to UV radiation is a risk factor related to cataracts. The degree of risk is based on a many things such as environmental conditions (cloud cover, geography, altitude ) and lifestyle factors (time spent outdoors and the nature of that activity). UV-Blocking contact lenses help against harmful UV rays, but formal studies have not been done to prove wearing UV-Blocking contact lenses helps reduce the risk of cataracts or other ocular problems. Ask your contact lens fitter for more information.
