What are photochromic lenses and why do you need them?
Oakley photochromic lenses are adaptive lenses that darken and lighten in response to direct sunlight. They are ideal for runners and cyclists who often face changing weather conditions. They are also a great choice for wearers who prefer not to switch glasses when moving from indoors to outdoors.

How does a photochromic lens work?
When the lens is active (clear), it blocks 31% of ambient light. At its darkest, the photochromic lens blocks 77% of ambient light. Like all Oakley lenses, Photochromic filters out 100% of UVA, UVB and UVC radiation. This protects your eyes from many health risks.
In addition, the lens is impact resistant. Oakley tests its products in extreme conditions to ensure the highest possible impact resistance, giving you the protection and peace of mind to focus on your performance at the highest level. Like all Oakley lenses, these lenses also feature High Definition Optics (HDO) to deliver the clearest, sharpest and most accurate vision possible in today's sunglasses.
