From Bausch & Lomb, Purevision is a popular and renowned product
line of contact lenses that allows for continuous wear thanks
to advanced technology that combines thin lenses with high moisture and good
oxygen transmission. However, it's important to note that continuous wear should
not be undertaken without explicit advice from your eye specialist. Both the
usual Purevision and its successor, Purevision 2 - also called Purevision 2HD-
remain popular. This line guarantees even sharper vision and greater comfort.
