Lens Pure Vizion, contact, monthly

The secret behind Bausch and Lomb's PureVision contact lenses is that they’re constructed of a unique AerGel silicone hydrogel material. AerGel, along with a Performa surface, delivers an enhanced ability to retain moisture and resist the buildup of protein deposits. This special material does not impede the flow of oxygen or fluid, keeping the eyes comfortable all day. As the first lenses made with AerGel, PureVision contacts contain 36 percent water and provide the eyes with an exceptional level of oxygen. Additionally, the surface is treated to stay moist using the eyes’ natural tears. For crystal-clear clarity that brings detail to life, the high-definition aspheric optical design of PureVision contacts provide enhanced focus and vision.                                                                                                                                                                 Bausch and Lomb's PureVision are monthly contact lenses, providing visual clarity and comfort that will fit even the busiest of lifestyles. You can wear them continuously during this period; throughout the day and night, and even while sleeping. Once the lenses are removed and replaced with a new pair of PureVision contacts, it is recommended that you let your eyes rest by not wearing contact lenses for at least one night. Under your doctor’s recommendation, you can also select daily wear use and wear them during the day, remove them before bed, and replace with a new pair after thirty days of wear.                                                                                                                                                               Since PureVision contacts can correct nearsightedness (myopia) or farsightedness (hyperopia), they’re an option for virtually everyone who may require vision correction. The length of time you can continuously wear PureVision lenses will depend on the recommendations of your eye-care professional.
