Protecting the eyes from ultraviolet (UV) exposure
Long-term exposure to ultraviolet (UV) light is associated with an increased risk of cataract development.
Protective measures include:
- Wearing sunglasses with UV protection
- Using wide-brimmed hats in strong sunlight
- Limiting prolonged exposure to direct sunlight
These steps help reduce cumulative exposure over time.
Describes how the eye is made up of layers of tissue, and how these tissues can be affected by different wavelenths of UVR. UVA affects the retina, and UVB affects the lens and cornea. Noted link to cataract development. Sunglasses with a UV filter are recommended.Managing general health conditions
Systemic health plays an important role in eye health.
Conditions such as diabetes can influence how cataracts develop and progress.
Good management includes:
- Maintaining stable blood glucose levels
- Following medical advice for chronic conditions
- Attending regular health check-ups
Avoiding smoking
Smoking is associated with an increased risk of cataract formation.
Reducing or stopping smoking may help:
- Lower overall risk
- Slow the progression of lens changes
Supporting overall eye health
General health and lifestyle factors contribute to the condition of the lens over time.
Helpful measures include:
- Maintaining a balanced diet
- Supporting overall cardiovascular health
- Staying well hydrated
While these do not directly prevent cataracts, they support long-term eye function.
Regular eye examinations
One of the most important steps is regular eye assessment.
Even when cataracts cannot be prevented:
- Early detection allows for monitoring
- Changes in vision can be assessed accurately
- Other eye conditions can be identified early
Regular examinations ensure that any changes are managed appropriately.
What prevention does not include
There are currently no proven medications or eye drops that can prevent or reverse cataracts.
Products that claim to “dissolve” or “cure” cataracts without surgery are not supported by clinical evidence.
