How to Prevent Cataracts

According to the American Academy of Ophthalmology, cataracts affect over 24 million Americans ages 40 and older. Factors such as age, gender, and family history can increase the likelihood of developing cataracts. But these tips can help you prevent or slow down the progression of cataracts. 

Eat healthy foods

According to research, eating a diet high in antioxidant-rich foods can lower your risk of developing cataracts. Antioxidants are good chemicals in your body that fights off bad chemicals delaying oxidation. Oxidation causes cataracts by damaging proteins and fats in your eye’s lens. 

Eating foods rich in antioxidants, like lutein, carotenoids, selenium, zeaxanthin, and vitamins A, C, and E, can help protect your cells from damage. Even if you have cataracts, these nutrients slow down cataracts’ growth. Healthy foods containing these nutrients include vegetables, fruits, whole grains, oily fish, eggs, nuts, and seeds. 

Quit smoking

We all know smoking is bad for our hearts and lungs, but did you know that smoking is also harmful to your eye health? Cigarette smoke produces free radicals that harm your eyes, reducing the number of antioxidants in your body. These toxins accumulate and can cause cataracts.  

But you can control this risk by quitting smoking. When you quit smoking, your eyes heal from the damage caused by cigarette smoke. 

If you are a non-smoker, never start smoking. And if you’re a smoker, start a program with your doctor to help you quit smoking.

Limit alcohol consumption

According to a study published in the Journal of Optometry and Vision Science, drinking excess alcohol increases your chances of getting cataracts. Excess alcohol intake can prevent the liver and other organs from absorbing nutrients. This causes proteins and fats to accumulate in your body, leading to cataracts. 

You can control this risk by limiting your alcohol intake. That means consuming less than two standard-size drinks. If you have never drank, your chances of getting cataracts are even lower.  

Wear sunglasses

While sunglasses may appear to just be a trendy fashion accessory, they protect eyes from ultraviolet (UV) rays emitted by the sun. UV lights damage lens proteins in your eyes, leading to cataracts. 

When going out, wear appropriate sunglasses to protect your eyes. Select sunglasses that can:

  • Can screen out up to 99 percent of UVB and UVA rays.
  • Can block out about 90 percent of visible light.
  • Fit your face and are close to your eyes. 

Drink water

Did you know drinking enough water can help prevent cataracts? If you don’t hydrate, chances are your body will accumulate toxins. These toxins can affect your health, including your eyes, which can cause cataracts. 

Drinking enough water helps you flush out these toxins. Develop a habit of drinking water at regular intervals.

These foods are rich in vitamin C:

  • Citrus fruits
  •  Tropical fruits
  • Bell peppers
  • Broccoli
