# Can cataracts be prevented?

Cataracts cannot be completely prevented because ageing and genetic factors play a major role, but some risks can be reduced. Prevention focuses on limiting avoidable damage to the lens.

## Reducible Risk Factors

Stopping smoking, protecting the eyes from ultraviolet light, and keeping diabetes well controlled are key steps. Reviewing long-term steroid use with a doctor may also be appropriate if alternative treatments exist.

- Wear sunglasses that block 100% of UVA and UVB
- Manage blood sugar, blood pressure, and cholesterol levels
- Eat a balanced diet with plenty of fruit and vegetables

## Inevitable Changes

Even with excellent lifestyle habits, many people eventually develop cataracts because natural lens proteins change over time. When this happens, [cataract surgery](https://bluefinvision.com/cataract-surgery/) is the definitive treatment.
