Tokai is the only lens manufacturer using neuroscience to create bespoke progressive lens designs. The measuring and analysis of brain waves has led to the development of revolutionary progressive lens designs that are easy to adapt to and that reduce the amount of discomfort experienced by the brain. This dramatically increases the wearer’s comfort.
Many ocular diseases are thought to be caused by oxidative stress due to the generation of singlet oxygen. 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 that suppresses this oxidative stress and also filters blue light, both contributing to the prevention of Age-Related Macular Degeneration. AMD is the most common cause of vision loss for the 50+ age group.
TOKAI Lutina lenses have the ability to absorb light between 400 to 420 nm. Cutting light in this wavelength range effectively suppresses generation of active oxygen and deterioration of lutein. To help preserve the lutein in the eyes, TOKAI developed Lutina. This lens cuts out 94% of High Energy Violet Light (400 – 420 nm), and by doing so, helps to preserve ocular health.
In pursuit of the thinnest and lightest lens possible, TOKAI Optical has been successful in combining this new 1.76 index lens material with its in-house aspheric design concept, driving this class of lenses to new and undiscovered heights!
The ultimate combination of material, design and matching surface treatments are the basic guidelines handled by TOKAI in their permanent aim for implementing innovative research. On the basis of these principles, and taking into consideration the wearers expectations, the 1.70 AS removes any limitations towards perfection. A perfect balance between the optical performance, the cosmetic appearance and the wearer’s comfort.
