Eye protection from blue light and led monitors.

Tokai LUTINA lenses...

Tokai have recently introduced “LUTINA”, providing superior eye protection that absorbs the UV and high energy visible light (HEV) up to 420 nm (UV coatings absorb up to 400nm), which are linked to many eye disorders such as Age-Related Macular Degeneration.

Retinal damage caused by H.E.V.

The macular pigment which is made up of 3 caratenoids: lutein, zeaxanthin and meso-zeaxanthin reduces the effects of oxidative stress. As the eye ages the eye produces a waste product called lipofuscin which builds up inside the retinal pigment epithelium. This lipofuscin acts as a sensitizing agent and accelerates the oxidative stress and destruction of the retinal pigment. By cutting out the HEV (high energy visible light), it may be possible to reduce the oxidative stress and the destruction of lutein within the retina.

Up to 95% absorption of the harmfull radiation

Testing shows that only 5.89% of rays from 400-420nm pass through the “LUTINA” lens, much less than readily available blue blocking lenses from other companies (which allow up to 65% to pass through). When a UV pen is passed over a ”LUTINA” lens with a Transitions lens under it, the Transitions lens does not react.

LUTINA lenses are already available at Eye-Shop

As we are now living longer, protecting the retina at all ages is becoming more vital for conservation of vision. We look forward to offering this new technology lens to you. Ask in-store for more details.
