Color blindness primarily occurs due to genetic factors or damage to the eye’s cone cells. The most common types include:
- Red-green colorblindness (deuteranopia or protanopia) – affecting about 8% of males and 0.5% of females
- Blue-yellow colorblindness (tritanopia) – much rarer, affecting both genders equally
Color blindness can also be acquired through:
- Eye injuries or diseases
- Certain medications
- Aging processes
- Exposure to harmful chemicals
While there’s no cure for genetic color blindness, special glasses and digital tools can help affected individuals distinguish colors better in daily life.
