Are All Cataracts the Same?
No! There are numerous types of cataracts, but 3 of the most common types are:
- Nuclear: Cataracts that form in the lens’s nucleus. These cataracts usually appear as people age, but you might be able to lower your risk of developing them with a healthy diet.
- Subcapsular: Cataracts affecting the back of the lens. Subcapsular cataracts are common in those who have diabetes, as well as people who use certain steroids.
- Cortical: Cataracts that appear in the lens cortex near the central nucleus and gradually spread across the lens from the edges.
Why Do Cataracts Appear?
Cataracts become more likely as you age, but they can be caused by other factors too. The following factors may increase your risk of developing cataracts:
- Diabetes
- Injuries
- Radiation exposure
- Post-operative eye surgery complications
- Smoking
- Poor diet
- Alcoholism
