Cataracts are a leading cause of blindness in the U.S., but you can reduce your risk of getting them. The most common surgical procedure in the nation, cataract surgery is performed over two million times a year.1 Cataract prevention is a hot topic. It may be possible to prevent or at least delay the progression of cataracts.

How to Prevent Cataracts

Uncontrollable risk factors—including age, family history, ethnicity, and gender—are involved in cataract formation. Factors you can control include:


Changing your diet can lower your cataract risk. Antioxidants can help protect against and slow the progression of cataracts. Vitamin C has been found to reduce the risk of developing cortical and nuclear cataracts, while vitamin E has been associated with a decreased risk of nuclear cataracts as well. Multivitamins and supplements can be effective.

The carotenoids lutein and zeaxanthin, found in green, leafy vegetables and eggs, can reduce the need for surgery and the risk for developing new cataracts. Foods to prevent cataracts include:

  • Kale: Contains lutein and zeaxanthin, as well as vitamin C and beta carotene, all of which are eye-healthy.
  • Sweet potatoes: A good source of beta carotene, which is converted to vitamin A in the body.
  • Strawberries: Contain plenty of vitamin C to help reduce your cataract risk.

Green tea can also improve eye health. It contains many antioxidants, including catechins, which can lower the risk of developing cataracts, as well as macular degeneration.

Quit smoking

Smoking creates free radicals that can harm eye cells. It can cause blood vessel problems too. Also, good chemicals from food that fight off free radicals are killed by smoking. Too many toxins can lead to cataracts, but, by quitting smoking, you can prevent them even if you have smoked cigarettes in the past.

Wear Sunglasses

You may look hip and trendy in those shades, but did you know sunglasses can reduce your risk of developing cataracts? If you’re concerned about cataract prevention and treatment, try to avoid ultraviolet (UV) light exposure as much as possible. Lens proteins are damaged by UV light. For the most protection, look for sunglasses that block 99% to 100% of UVA/UVB rays, that screen out 75% to 90% of visible light, and that fit the shape of your face.

Limit Alcohol Consumption

You don’t have to eliminate alcohol entirely, but drinking too much can increase your cataract risk. Research has shown that having more than two drinks a day raises your odds. However, drinking fewer than that can lower your risk of getting cataracts.2

High blood sugar can cause the lens to swell, so it’s important to control, especially if you have diabetes, which is often associated with cataracts. Controlling high blood pressure is important as well. Regular eye exams can enable your eye doctor to spot problems early and address any risk factors.
