Can contact lenses block ultraviolet light?
Although some manufacturers have added UV blocking properties to some lenses, none block all of the harmful UV light. Health organizations state that contact lenses are not a substitute for UV absorbing eyewear such as UV absorbing sunglasses in part because contact lenses cover only a portion of the eye. It is recommended to wear UV absorbing sunglasses over your prescription contact lenses, even if they contain UV blocking properties.
