1-Day Acuvue allows you to start every day with a fresh, clean pair of contact lenses. It is the perfect way to ensure that deposits never have a chance to build up and irritate your eyes. These lenses are tinted for ease of handling and will not change the color of your eye. The tint is simply designed to facilitate locating the contact lenses in solution. They also contain an inside-out "123" indicator to help ensure proper application/insertion.
