Lenses To Filter blue-violet light*
How does blue light affect our sight?
Most of us think of light as the absence of darkness; light is either present or absent, either natural or from a man-made source. While none of that is incorrect, there is actually much more to light than (pardon the pun) meets the eye.
For both indoor and outdoors
As the sun is the largest source of blue-violet light*, protecting our eyes against man-made sources is not enough for those who lead active lifestyles. Clear protective lenses like Crizal® Blue UV Capture™ filter out both UV and blue-violet light* while letting beneficial light to pass through, providing a trusted solution for all.
Another effective method is to use photochromic lenses that are clear in low light conditions but darken as the light increases. Transitions lenses offer optimal protection from UV rays from both the sun and blue-violet light* from digital devices and house lights.
These glasses are suitable for wearers of all ages, a clear advantage especially with children under the age of 12 who are more vulnerable to sun damage due to the fact that their eyes’ natural protective barriers are still underdeveloped.
