Blue-Violet light and blocking lens treatment options

2016-12-27 18:59:46

Nowadays, most people spend a significant amount of time in front of digital devices, which are often emitting intense blue-violet light.  Virtually all visible blue light passes through the cornea and crystalline lens and reaches the retina.  Some studies have suggested that increased blue-violet light exposure, specifically in the range of 430 to 440 nanometer, may increase the risk of macular degeneration and cataract and could potentially cause eye strain, headache, and interfere with normal sleep cycles.


Several lens manufactures have come up with selectively blue blocking lens treatment option to reduce this risk and enhance digital screens.  Many of those lens treatment options now come equipped with scratch and smudge resistant coat for better durability and easier clean.  This technology would potentially allow for reduced glare, optimized transparency and more comfortable wearing experience.
