Color Blind Suffers Experience Sunglasses Relief

This is an Advertorial

Color blindness is considered a medical color deficiency. People that suffer from this disability see colors differently, albeit it in a decreased or altered perception. Color blindness is very popular and affects a significant number of the world’s population.

Color blindness is not indicative of the medical definition of blindness and simply means that one or more sets of retinal cones did not fully develop. This results in color being perceived in an altered state by the body’s optic nerve. Generally sex-linked, more men exhibit colorblind symptoms than comparable female populations. The colorblind chromosome being attached to the X chromosome causes this. Since men only have one X and one Y chromosome and women have two X chromosomes, the chances of men’s X chromosomes having a color deficient defect are higher.

Color blindness can also result from chemical or physical damage to the eye, brain or optic nerve. Considered a mild disability, many colorblind men suffer from red-green color blindness. It is estimated that nearly eight-percent of men and half-a-percent of women suffer from some form of color blindness.

There are several types of color blindness. While some can be acquired, generally most are inherited. There are three different types of hereditary color blindness.

Monochromacy – This is known as a complete and total loss of color, where the afflicted individual only sees monochromatic – black and white – colors.

Red Monochromacy – This is rare, but causes sensitivity to light and leads to exceptionally poor vision.
Cone Monochromacy – Extremely rare, this color blindness features normal vision.

Dichromacy – This is where one of the three main color mechanisms does not function properly or is completely absent.

Protanopia – This is caused by the absence of the red retinal photoreceptors. Red appears similar to black and purple and blue cannot be distinguished from one another. Orange and red may appear to have a dim yellow appearance and some green-orange-yellow shades look yellow. This is a hereditary condition that affects 1% of the male population.
Deuteranopia – This color vision disorder affects red-green hues and is also hereditary.
Tritanopia – This rare condition results in a complete absence of blue receptors. This means that blue appears green, orange and yellow look pink and purple mimics a deep red. This disorder is associated with an altered Chromosome 7.

Anomalous Trichromacy – This is extremely common and results in color sensitivity.

Protanomaly – This is a mild condition that results in sensitivity to red receptors and makes it difficult to distinguish between red and green.
Deuteranomaly – Very common, this mildly influences red and green tones and affects nearly 5% of European males.
Tritanomaly – Extremely rare, this disorder is not sex-linked and affects blue and green, yellow and red/pink tones.

Many people who suffer from colorblindness report that they have difficulty seeing and distinguishing the difference between red and green traffic signals. Fortunately, grey shades of wholesale sunglasses help reduce the effects of color blindness. In fact, professional experts recommend that suffers avoid wholesale designer sunglasses that have red-brown or yellow-brown tints, as these don’t offer enough contrast against red traffic lights. Yellow-green lens tints offered minor difficulties for distinguishing the differences between green and yellow traffic lights.
