PureVision contact lenses are made from silicone hydrogel, designed to be worn for up to 30 days and then replaced with a fresh pair. Bausch & Lomb's special AerGel design allows a natural level of oxygen to permeate the lens, so the lens feels more comfortable. PureVision lenses are uniquely engineered to stay moist and wipe away debris from the surface.
These lenses can be worn continuously, even when asleep, but we recommend that you speak to your Optician about whether this is a good option for you. Not everyone is suited to continuous wear contact lenses.
