However in Europe, about 8% of men and 0.5% of women in the Caucasian population suffer from some type of congenital anomaly in the performance of some of the cones, which causes color vision deficiencies. These cones are sensitive to short wavelengths (S), medium wavelengths (M) and long wavelengths (L). “normal human color vision is trichromatic thanks to a cluster of three types of photoreceptors known as cones, which are present in the retina. Luis Gómez Robledo, professor from the UGR Department of Optics and one of the authors of this paper, explains it all in a bit more detail … The results show that the glasses introduce a variation of the perceived color, but neither improve results in the diagnosis tests nor allow the observers with CVD to have a more normal color vision. In the second, we use the spectral transmittance of the glasses to simulate the appearance of stimuli in a set of scenes for normal observers and observers with CVD.Īs you can probably guess, the magic glasses did not deliver on the promises … The first consists of using the three classical types of tests - recognition, arrangement and discrimination - with and without glasses, with a high number of individuals. We evaluate the effectiveness of these glasses using two complementary strategies for the first time. They were asking the rather obvious question – Do EnChroma glasses enable colour blind people to be able to see new colours or even correct colour vision deficiency (CVD)? What was the study focused on finding out? Do EnChroma glasses improve color vision for colorblind subjects? They are very expensive, but if they actually work, then it would potentially be a life changing pair of glasses.Ī study has been published in Optics Express in which Scientists from the University of Granada ran some tests to find out.
They specifically claim that these glasses …īring vibrant color to adults and kids with STRONG PROTAN color blindness
People who have this generally adapt quite easily without too much trouble, but as a note of caution, if you are profoundly red-green colour blind then please, for your own safety, don’t consider a career as an electrical engineer.ĮnChroma glasses have been commercialised as a solution. It can manifest to varying degrees and so it can be modest or quite profound. The picture above gives you an idea of what that might be like. Color blindness means that the light-sensitive cells in the retina are not responding appropriately to variations in wavelengths of light that enable people to see an array of colors.
