What are Photochromic Lenses?

Photochromic lenses, also known as light-adaptive lenses, darken in bright light and become clear once a person is indoors. The transition is activated by UV radiation, and thus, the lenses get to adjust according to the actual current lighting conditions, bringing about improved vision with better protection from the sun.

Key photochromic lens technology is the use of photochromic molecules in the lens material. It changes the structure upon exposure to UV light, thus making the lens darker. The lenses will go back to their first light state once the UV diminishes.

Benefits of Photochromic Sunglasses

Enhanced Comfort and Convenience

Versatility Across Activities

Photochromic lenses are also used in spectacle lenses. This photochromic spectacle lens is designed to absorb ultraviolet radiation and become darker whenever the sunlight radiation becomes intense. For this reason, the versatility in photochromic sunglasses has proven that this kind of lens is very widespread. This applies, especially to all kinds of people’s outdoor activities, like cycling or skiing.

Improved Visual Acuity

Photochromic sunglasses work by tinting and changing their shades in such a way that they optimize the capability of the lens in filtering light, reducing eye strain, and allowing clarity from the eyewear across changing light conditions. This now becomes the most beneficial when adjusting to keep a constant vision during the transition from one lighting environment to another.

Cost Effectiveness

This precludes the purchase of two different kinds of glasses: sunglasses and spectacles if one invests in photochromic sunglasses. The dual purpose of saving money is no doubt quite convenient and thrifty in the long run.
