PureVision monthly lenses

PureVision are monthly contact lenses manufactured by 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 content. This effectively prevents dry eyes. The combination of silicone and hydrogel provides high wearing comfort, especially for people with dry eyes. Typically, dry eyes are exacerbated by prolonged wear and are further intensified in air-conditioned environments with low humidity. The special composition of the Balafilcon A material helps prevent dry eyes and allows for comfortable wear even over extended periods. PureVision lenses are characterized by high oxygen permeability. The eye receives a natural supply of oxygen, and the transport of fluids within the eye is minimally affected by wearing the lens. Thanks to a special surface treatment, the lenses are resistant to dirt and deposits. Unlike a coating that can wear off over time, PureVision lenses have been treated using a special process that affects the material itself. 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 wearing comfort and naturally healthy eyes. PureVision contact lenses are designed for a usage duration of up to 30 days.
