EnChroma glasses to help colour-blind people see colours. (PIcture from: http://bit.ly/1UagK0J) |
For
those who suffer from color blindness, one of the cone cells in the eye
is not working properly, so they are not able to distinguish colors
correctly. In most cases of color blindness, damage occurs to the red or
green cone cells, causing the sufferer trouble distinguishing a variety
of colors. In addition, in some cases the cone cells will capture the
color spectrum overlap.
EnChroma,
an eye lens company founded by an American surgeon creates glasses that
are able to restore the function of the receptor cells of damaged eyes.
The glasses have filters that can capture light spectrum overlap each
other, pushing the "wedge" that makes the frequency of the light collide
with each other. By using the glasses, those with color blindness can
taste the beautiful range of colors around them through the EnChroma
lens.
