Globally recognized as the top choice for photochromic lenses, Transitions® lenses are recommended by eye care professionals. These lenses utilize patented, photochromic dyes that allow them to quickly activate and darken when exposed to ultraviolet light from the sun. The intensity of UV rays determines the darkness level of the lenses, with higher intensity resulting in darker shades. When there is no UV light, such as indoors or at night, the lenses gradually return to their original state.

Transitions® lenses are incredibly versatile. They go beyond the simple transition from clear to dark, demonstrating excellence in finding the perfect shade for every lighting scenario. Regardless of whether you find yourself indoors, outdoors, or somewhere in between, Transitions lenses effortlessly adjust to deliver the optimal amount of light. As a result, you can experience the world with unparalleled clarity and comfort, ensuring a truly enhanced vision.

Eyewear equipped with Transitions lenses® incorporates special photochromic lenses that have the ability to adjust the tint level. These lenses transition from a clear and transparent state to a darker shade resembling sunglasses. The tint shift occurs gradually, and there are multiple stages of tint coloring and darkness intensity. These lenses “activate” in response to sunlight, specifically the sun’s UV rays.

On average, it takes between 30 seconds to a minute for the lenses to darken completely. However, when the lenses are no longer exposed to UV rays, it may take several minutes for them to fully return to a clear state.

The degree of darkness is determined by the intensity of UV light, the time of day, and the direction of the sun. Various factors such as extreme temperatures, UV exposure, and the materials used in the lenses can also affect the level of darkness in photochromic lenses.

It’s important to note that the effectiveness of the transition is not dependent on the brightness of the sun, but rather on the exposure to UV rays. Therefore, even on slightly overcast cold winter days, the transition of your lenses will still work properly. The main difference is that in colder temperatures the darkening process is slower, and it takes more time for the lenses to transition back to lighter shades. These are because the molecules responsible for the transition slow down in colder conditions.
