Lesa Glasses for Daltonism

Valuable aid in everyday life!
The effect of tinted filters, which enable colour perception, is immediately felt by colour-blind people when they try on the lenses. These new tints offer a significant increase in contrast to combat dyschromatopsia. 

Principle
Colour-blind people who are deficient in red and green will have difficulty in visually separating these two colours. The tints help to accentuate the difference contrast between them.

The green colour of the light spectrum will be attenuated, and the red will be accentuated. As a result, the contrast becomes significant, giving colour-blind people a better perception.

In order to achieve the best possible visual compromise, 4 categories of tints have been created with 4 tint intensities. This offers a choice of 16 tints. It is advisable to try these tints in order to choose the one best suited to the wearer.

Style
We can produce these tints on all types of eyewear such as prescription lenses, non-prescription lenses, clip-on, over glasses, etc.
