This time-tested contact lens was introduced in 1999. ACUVUE® 2 contact lenses are designed for a two-week replacement schedule with a daily wear or up to a one-week continuous wear schedule. While your eye care professional is determining the exact replacement details, these lenses support a 7-day continuous wear schedule. This means that you put them in, live and sleep in them for up to seven days, and start with a fresh pair. In addition, the thin INFINITY EDGE™ Design supports a softer feel and more oxygen to be transmitted to the eye.
