Monochromatism - Assignment Example

Monochromatism: A on how it works It is a condition where by one possesses only one channel of relaying information on color. Those who suffer from this deficiency have an absolute inability to differentiate colors and recognize disparities in brightness. The situation occurs in two basic forms: The first being rod monochromacy in which the retina possesses no cone cells. Therefore, in absentia of discrimination of color, light visions intensity is not easy. The other one is the cone monochromacy where one has both cones and rods, although only one type of cone.

This condition has god vision of patterns at daytime but cannot distinguish hues. The blue monochromacy is due to total absence of M and L cones. It’s encoded in the same place like the green-red color blindness situated on X chromosomes (Grosvenor, 2006)Description of an example of MonochromatismThe victims of the situation recognizes a variety of shades moving from black to white with no gray and except for if it is needed to employ color names that are correct to converse with people who are normally sighted.

The victims who suffer the deficiency refer to the color of things as ‘darker than’ or ‘lighter than’. Lastly, the individual forms high sensitivity to light and develops phobia to light. As cones do not function in these victims, the rods in the eyes will saturate illuminations at high levels (King, 2012)Description of its impactThe individuals suffering from the deficiency suffer from day blindness. The colors in the cone contain chemicals that stabilize in bright light hence allow people to visualize through bright light.

The victims miss the chemicals hence may not be photophobic making the blue cones work. The cones, therefore, do not function well and this may lead to a reduction in vision (Goldstein, 2010)ReferencesTheodore Grosvenor (2006) Primary Care Optometry, (Grosvenor, Primary Care Optometry) 5th edLaura King (2012) Experience Psychology. 2nd edition: Paperback, McGraw Hill Higher EducationGoldstein, E.B.
