PureVision monthly lenses

PureVision are monthly contact lenses from the manufacturer Bausch & Lomb. They are made from the newly developed silicone hydrogel Balafilcon A, which, due to its low water content of only 36%, draws significantly less moisture from the eye compared to lenses with a higher water percentage. This effectively prevents dryness of the eyes. The combination of silicone and hydrogel provides high wearing comfort, especially for people with dry eyes. Typically, eye dryness is exacerbated by prolonged wear and is further intensified in air-conditioned environments with low humidity. The special composition of the material Balafilcon A helps to prevent dry eyes and allows for comfortable wear even over extended periods. PureVision lenses feature high oxygen permeability, supplying the eye with a natural level of oxygen while minimally affecting fluid transport in the eye during lens wear. Thanks to a special surface treatment, the lenses are resistant to dirt and deposits. Unlike a coating that can wear off over time, PureVision's material has been treated with a special process. This ensures that the outstanding surface properties of the lens are maintained throughout the entire wearing period. The result is unique visual quality with high comfort and naturally healthy eyes. PureVision contact lenses are designed for a usage duration of up to 30 days.
