Color blindness occurs due to several factors, with the most common being genetic inheritance, particularly in males. The condition typically results from:
- Missing or damaged cone cells in the retina
- Mutations in genes that produce photopigments
- Injury or damage to the optic nerve or brain
The most common form is red-green color blindness, affecting approximately 8% of males and 0.5% of females of Northern European descent. Complete color blindness (achromatopsia) is very rare. Some cases can be acquired through eye diseases, certain medications, or aging. While there’s no cure for genetic color blindness, special glasses and digital tools can help affected individuals distinguish colors better in daily life.
