PureVision are monthly lenses from Bausch & Lomb. They consist of the newly developed silicone hydrogel Balafilcon A, which absorbs much less moisture from the eye than lenses with a higher water content due to its low water content of only 36%. This effectively prevents the eyes from drying out.
The combination of silicone and hydrogel results in a high wearing comfort, especially for people with dry eyes. Usually, the drying out of the eyes is facilitated by a long wearing time and is even intensified in air-conditioned environments with low humidity. The special composition of the material Balafilcon A prevents dry eyes and makes it comfortable to wear over long periods of time.
PureVision lenses are characterized by a high oxygen permeability. The eye is supplied with a natural oxygen content and the fluid transport in the eye is hardly affected by wearing the lens. Due to a special surface treatment, the lenses are insensitive to dirt and deposits. In contrast to a coating that can wear off over time, PureVision treated the material itself with a special process. The outstanding surface properties of the lens are thus maintained throughout the entire wear time. The result is a unique visual quality with high wearing comfort and naturally healthy eyes.
PureVision contact lenses are designed for up to 30 days of use. In consultation with the ophthalmologist or optician, the lenses can either be removed in the evening or worn throughout the day. The lenses are long-lasting and require little maintenance, which means that they can be seen clearly and comfortably at all times.
