How to prevent cataracts?

Cataracts are the most common cause of vision loss in older adults. But is there anything you can do to prevent them?

While cataracts can't always be avoided entirely, especially as you age, there are steps you can take to slow their development and protect your vision for as long as possible.

In this blog, we'll explore what causes cataracts and share practical lifestyle tips that may help keep your eyes clearer for longer.

What are cataracts?

Cataracts occur when the natural lens in your eye becomes cloudy. This process usually happens with age, but it can also be linked to:

• Sun exposure
• Smoking
• Diabetes
• Certain medications (like steroids)
• Eye injuries or surgeries.

Once a cataract forms, it won't go away on its own. The only way to treat it is through surgery.

Can cataracts be prevented?

There's no guaranteed way to prevent cataracts entirely—but by protecting your eyes and your overall health, you may delay their onset or slow their progression.

9 ways to reduce your cataract risk

1. Wear sunglasses

UV light can speed up cataract formation. Wear sunglasses that block 100% UVA and UVB rays whenever you're outdoors.

2. Stop smoking

Smoking increases your risk of cataracts. If you smoke, quitting is one of the best things you can do for your eyes (and your overall health).

3. Eat a healthy, colourful diet

Foods rich in antioxidants—like spinach, carrots, oranges, and blueberries—support eye health. Vitamins C and E, lutein, and zeaxanthin may all help.

4. Control medical conditions

High blood sugar and high blood pressure can contribute to cataract development. Keep conditions like diabetes and hypertension well-managed.

5. Limit alcohol intake

Heavy alcohol use has been linked to faster cataract development. Moderate your intake to support long-term eye health.

6. Protect your eyes from injury

Eye injuries can trigger early cataracts. Use protective eyewear when playing sports, doing DIY, or working in dusty environments.

7. Review your medications

Long-term use of steroids (like prednisone) can increase cataract risk. Speak with your doctor about possible alternatives if needed.

8. Get regular eye exams

Early cataracts may not cause symptoms. Regular check-ups help catch changes early so your care can be tailored accordingly.

9. Stay active and maintain a healthy weight

Exercise improves circulation and reduces inflammation—both of which are good for your eyes.

What about supplements?

Some studies suggest that antioxidants and certain vitamins may help reduce cataract risk. However, supplements shouldn't replace a healthy diet. If you're considering them, speak with your doctor first.

When prevention isn't enough

Even with excellent lifestyle habits, cataracts can still develop over time. Ageing is the biggest risk factor—and no one is immune.

The good news? Cataract surgery is safe, quick, and highly effective.

With modern lens implants, especially those used in private surgery, many people even find they see better after surgery than they did before cataracts began.

When to consider surgery

You may benefit from cataract surgery if:

• Vision feels cloudy or dim
• Lights seem too bright or create halos
• You struggle to read, drive, or work comfortably
• Glasses no longer seem to help.
