Transitions lenses are the #1 eyecare professional-recommended photochromic lenses worldwide. Transitions® lenses are equipped with patented, photochromic dyes that enable the lenses to rapidly darken, when they are exposed to ultraviolet light. The greater the intensity of UV rays, the darker the lenses become. When UV light is no longer present (indoors or at night) the lenses fade back to their original state.
To meet the diverse needs of our consumers, we have different lens options, which include our family of everyday lenses: Transitions Signature lenses, Transitions® XTRActive™ lenses and Transitions® Performance Sunwear which are adaptive sunglasses that go from a tint to a darker tint, depending on how much sunlight is present.
