Ophthalmic optics. Contact lenses. Ageing by exposure to UV and visible radiation (in vitro method)1 Scope This International Standard describes an in vitro method which simulates the ageing of rigid (hard) and soft lenses in daylight. The existence of this International Standard does not imply in any way that the testing of contact lenses for ageing by ultraviolet (UV) and visible radiation is a requirement.
