Photochromic Lenses: Adapting To You And Your Life.

Photochromic lenses, such as the Transitions® lenses family of products, automatically change from clear to dark in the presence of ultraviolet or UV radiation. They adapt automatically for enhanced visual comfort in changing light conditions. Available in a wide range of lens products, photochromic lenses are engineered to adapt to you and your life. Whatever your prescription needs – standard single-vision lenses, bifocals, trifocals, progressive lenses, shatter-resistant lenses, scratch-resistant lenses, even polarized lenses – they are now all available as photochromic lenses.

How Do They Work?

Invisible UV radiation is present in sunlight. The brighter the sun – in other words, the more UV radiation increases – the more photochromic lenses adapt by darkening. This not only protects your eyes against the visible glare of the sun, it also offers you 100% UV protection from the harmful affects of UVA and UVB rays.

Remove the exposure to UV rays, and photochromic lenses return to their clear state. Since photochromic lenses are clear indoors and get darker outdoors automatically they are among the most popular all-purpose lenses recommended by eyecare professionals.

Photochromic lenses can be enhanced even further with popular additional treatments like anti-reflective (AR) coatings for cutting glare as well as scratch-resistance, making photochromics among the most versatile eyeglass lenses technologies available on the market today. Adding to the Transitions lenses family of photochromic products is a revolutionary new product: Transitions® Vantage™ lenses, which combines photochromic technology with variable polarization. They are virtually clear indoors, with no polarization. Outdoors, they polarize with the degree changing depending upon the level of UV exposure.

Above all, don't confuse photochromic lenses with sunglasses! Unlike sunglasses, photochromic lenses are clear lenses that do more, automatically darkening when exposed to UV light. They are a great everyday solution for indoors and outdoors. However, many people are also interested in a second pair of sun lenses for enhanced visual performance outdoors or when driving and behind the windshield of a car. For these wearers, Transitions® Performance sunwear offer an excellent alternative to conventional sunwear. Transitions Performance sunwear go from dark to even darker in UV light – adapting to optimize colour and darkness in changing light conditions.

The Future Is Now.

Though photochromic lens technology has been around for over 40 years, new advances such as variable polarization and performance sunwear designed for specific activities mean the technology is more useful, relevant and exciting than ever before.
