Our exposure to blue light is growing as we are living longer than ever before, exposing ourselves to more and more artificial lights and digital devices. Overexposure to blue light may have impact on outer retina and may cause retinal cells death.
Thanks to a combination of carefully selected molecules at the very heart of the lens, Blue UV Capture ™ efficiently filters out harmful blue-violet light while letting beneficial blue-turquoise light pass through. Blue UV Capture ™ lens feature offers up to 3 times more protection against harmful blue-violet light than regular prescription lenses.
Due to the principle of complementary colors, cutting blue light leads to a yellow residual tint on the lens. According to the laws of physics, if an object absorbs a color, it will appear as its complementary color. As blue and yellow are complementary colors, the block of blue violet light gives the lens a yellow residual color.
A coloring agent has been added to blue UV Capture ™ lens to neutralize the yellow residual tint for an optimal clear lens.
The combination of Blue UV Capture ™ lens with Crizal Prevencia coating offers:
Up to 5 times more protection against harmful blue-violet light than regular prescription lenses.
