Eye diseases, including corneal ulcers, can develop quickly and lead to loss of vision. Lenses should not be left on overnight unless they are designed to do so and have been approved by an ophthalmologist. Clinical studies have shown an increased risk of serious adverse reactions if lenses are left on during the night. Extended wear lenses should be removed regularly for cleaning and disinfection or for destruction and replacement as recommended by your ophthalmologist.

Do not use water, such as tap, bottled or distilled water, or any non-sterile solution when storing or rinsing lenses. The lens case should be cleaned, rinsed and air dried each time the lenses are removed from it. To remove excess solution, you can turn the lens case upside down to dry.
