Self-Care Guidelines
There are no proven ways to prevent cataracts, but there are several things you can do that may affect the development of cataracts.
  • Avoid smoking.
  • Use sunglasses with UV protection.
  • Follow a healthy lifestyle with diet and exercise.
  • Avoid long-term exposure to X-rays.
  • Avoid alcohol abuse.
  • Maintain strict control of diabetes if applicable.
  • Use of anti-oxidant vitamins may slow the development.
The side effect of some medications is the development of cataracts, such as long-term use of steroids at high enough levels. Additionally, certain general diseases, such as diabetes, are associated with cataracts.
When to Seek Medical Care
When vision is affected enough to interfere with your life and lifestyle, seek professional care. For example, if you are changing your glasses frequently due to cataracts.
