Biotrue ONEday contact lenses are inspired by the biology of your eyes. While other lenses dry out as the day passes, Biotrue ONEday contacts retain moisture naturally produced by the eye. The result is consistently clear vision and comfort until the moment you take them out. With added High Definition Optics, Biotrue lenses help reduce halos and glare in low light situations. Try Biotrue ONEday daily disposables and see how naturally good your eyes can feel in contact lenses.
