Remove the lenses every day, then clean, disinfect and store them with an appropriate contact lens solution according to its instructions. Replace the lenses after two weeks from first use. Wash and dry your hands before handling them and avoid exposing lenses or the storage case to water. UV-blocking contact lenses are not a substitute for UV-protective sunglasses because they do not fully cover the eye and surrounding area. If you experience pain, persistent redness, irritation or a change in vision, remove the lenses and consult an eye care professional.
