Transitions® Lenses

Transitions® lenses are the top-performing photochromic lenses on the market. Transition lenses change more quickly than other photochromic lenses and activate up to a category 3 darkness outdoors. Plus, they pack the value of hassle-free comfort, versatility, and protection. Transition lenses are great if you are looking to make a single purchase because they offer the benefits of clear lenses, sunglasses, and blue-light blocking lenses all in one photochromic package. Zenni is proud to offer the best value for Transitions® lenses on the market. For more information about Transitions® lenses, visit https://www.transitions.com/en-us/.

The molecules in photochromic technology work by reacting to UV light. However, temperature can affect the molecules’ reaction time. Colder temperatures mean molecules move more slowly, and it will take longer for transition lenses to adapt from dark to clear, even on sunny days. Warmer temperatures mean molecules speed up and become more reactive, meaning a faster fade back from dark to clear. Moving from sun to shade in warmer climates, your lenses will be quicker to detect the diminished UV rays and will lighten in color. Transitions® Signature® GEN 8™️ lenses are more responsive than previous generations: fully clear indoors, darker outdoors, and returning to clear indoors, faster than ever.

Yes! All photochromic lenses offered at Zenni are great options for your general eye health. In addition to blocking 100% of UVA/UVB light, the adaptive, two-in-one nature of photochromic glasses reduces squinting and eye fatigue. For those looking to replace their sunglasses with a photochromic lens, we suggest choosing Transitions® XTRActive® Polarized™, which will also protect your eyes in the car by darkening while you drive and polarizing in direct sunlight for clearer sharper vision.

To preserve the longevity and performance of your transition glasses, clean them regularly with a soft, lint-free cloth. Don’t use abrasive substances or harsh chemicals on transition lenses. For a more thorough cleanse, use a mild lens cleaner, followed by drying with a clean cloth. Regular cleaning of your transition lenses not only guarantees crystal clear vision but also extends the lifespan of your eyewear.
