LUTINA
The Ultimate In Light Protection
Lutina
Reduce Damage. Reduce Glare. Protect The Eye.
Tokai’s Lutina coating reduces the amount of high energy violet (HEV) light by around 94%. This light is responsible for the most amount of glare caused by headlights and other artificial light sources(1). It is also thought to cause damage to the retina. Lutina effectively reduces this light, and preserves one of the most important pigments in the eye - Lutein.
The Lutina Difference
-
A UV filter only stops UV light, not HEV light, from enterting the eye. HEV light has been shown to cause damage to the retina(2). Lutina lenses stop both UV and HEV light.
-
Anti-reflection coatings are great at reducing reflections - and our Lutina lenses come with anti-reflection coating built in. What they don’t do is reduce glare from HEV light. Lutina does.
-
Blue filters are very popular and may help reduce problems associated with sleep and artificial light. But they can also reduce night time vision(3), and have less of an effect on glare than Lutina, because Lutina stops HEV light - which is before blue light on the visible light spectrum.
