The performance life of a Transitions® lens will generally last the lifetime of the prescription which is normally 2 years. This is in keeping with industry standards for frames, coatings and other treatments that come on prescription glasses. After exposure to the sun for a period of time, the technology will eventually start to fatigue. In most cases, Transitions lenses may activate for even longer than 2 years, but it will depend on the amount of UV exposure to the lenses.
