Photochromic Lenses
Whether you are exploring the city or strolling in the mountains, photochromic lenses are your perfect travel companion. They change color when exposed to light and automatically adapt to different light environments, allowing you to always have a clear vision, focus on the beautiful scenery in front of you, and capture every beauty of life.
What Are Photochromic Lenses?
Photochromic lenses are Eyeglass Lenses where photochromic molecules on the lens react to light and change their structure, causing the lens to darken.
What Are Photochromic Lenses Used For?
Photochromic lenses are ideal for people who need to wear glasses all of the time. The two main purposes of photochromic lenses are to protect your eyes from UV light and to eliminate the need for a separate pair of prescription sunglasses.
The lenses provide complete protection from UVA and UVB rays at all times. This protective feature doesn’t depend on whether the lenses are clear or dark at any given moment.
