deuteranopía

Deuteranopia is a form of red-green color blindness. Individuals with deuteranopia have a deficiency in their green cone cells, which are responsible for perceiving green light. This means they have difficulty distinguishing between certain shades of red and green. The world, for someone with deuteranopia, appears less vibrant, with reds and greens often appearing muted or as shades of brown or yellow.

This condition is congenital, meaning it is present from birth and is caused by a genetic mutation on the X chromosome. As a result, it is much more common in males than in females. Deuteranopia is a recessive trait, so a female must inherit the faulty gene on both of her X chromosomes to be affected, while a male only needs to inherit it on his single X chromosome.

Diagnosis is typically made through a series of color vision tests, such as the Ishihara plates or the Farnsworth-Munsell 100 hue test. There is currently no cure for deuteranopia. However, specialized glasses and contact lenses can help some individuals with deuteranopia perceive colors more accurately, although they do not restore normal color vision. While it impacts the perception of color, it does not affect visual acuity or depth perception.
