Lutina is a new lens material which helps to protect the wearer from the development of age related macular degeneration (AMD), a process of wearing down of the center of the retina. AMD is the most common cause of vision loss for the 50+ age group.
Studies show that the deterioration of Lutein within the macula can lead to the onset of Age-Related Macular Degeneration.
Lutein is one of the three carotenoid pigments that are present in very high concentrations in the retina of the eye or more specifically in the lens and macula.
It has antioxidant properties and also filters blue light, both contributing to the prevention of AMD.
As humans cannot naturally produce this essential substance, we depend on eating green and yellow vegetables to absorb and replenish its supply.
To help preserve the lutein in the eyes, Tokai developed Lutina.
This lens material filters the harmful UV-rays 380 nm and beyond 400mn, thus helping to protect the lutein in the macula, and by doing so, helps to maintain ocular health.
