It may be that the receiver is missing a color or that it is not sensitive enough. The result is that the color blind person can easily distinguish a tone or even, he may not perceive it at all.

 

This alteration is much more common in men. 6% of men and 0.4% of women have difficulties in green and 1% of men and 0.01% of women, with the red color.

The results are surprising in 80% of the cases. The lenses can be graduated in both distant and progressive vision. There are special lenses for interiors
