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.
