Color blindness occurs when one or more types of cone cells in the retina don’t function properly. The most common form is red-green color blindness, affecting approximately 8% of males and 0.5% of females. This condition is typically inherited through genes on the X chromosome.
There are several types of color blindness:
- Deuteranomaly: reduced green sensitivity
- Protanomaly: reduced red sensitivity
- Tritanomaly: reduced blue sensitivity
- Complete color blindness (achromatopsia): seeing only in grayscale
While color blindness cannot be cured, special glasses and lenses can help some individuals distinguish colors better by filtering specific wavelengths of light.
