PureVision monthly lenses

PureVision are monthly lenses of the manufacturer Bausch & Lomb. They consist of the newly developed silicone hydrogel Balafilcon A, which, due to its low water content of only 36%, extracts much less moisture from the eye than lenses with a higher water content. 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 favoured by a long wearing period and is intensified, for example, in air-conditioned environments with low humidity. The special composition of the material Balafilcon A prevents dry eyes and makes it pleasant to wear, even over longer 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. A special surface treatment makes the lenses insensitive to dirt and deposits. Unlike a coating that can rub off over time, PureVision uses a special process to treat the material itself. The outstanding surface properties of the lens are thus retained throughout the entire wearing period. The result is a unique visual quality with high wearing comfort and naturally healthy eyes. PureVision contact lenses are designed to last up to 30 days.
