How Can I Prevent Cataracts?

Expert Tips from Your Ophthalmologist

Cataracts, a leading cause of vision loss, affect over 24 million Americans over age 40. While cataracts often develop naturally over time, there are steps you can take to delay their onset and reduce your risk. By understanding cataract risk factors and maintaining good eye health, you can lower your chances of needing surgery in the future.

Here’s what you need to know about cataracts and how to prevent them.

What are Cataracts?

Cataracts occur when the lens of the eye becomes cloudy which results in blurred vision. This condition often worsens with age but can also be caused by factors like UV exposure, diabetes, or eye injuries. That’s why early cataract prevention is key to maintaining long-term eye health and avoiding cataract surgery.

Know Your Risk Factors

As you age, your risk of developing cataracts increases due to the natural breakdown of proteins in the lens. The Centers for Disease Control highlights that the risk of cataracts grows significantly after age 40. Other cataract risk factors include:

• Genetics and Cataracts: A family history of cataracts increases your likelihood of developing them.
• Medical Conditions: Diseases like diabetes accelerate cataract formation.
• Lifestyle, Age, and Cataracts: Smoking, excessive alcohol use, a poor diet, and age all increase cataract risk.

Diet and Nutrition for Eye Health

A nutrient-rich diet can help reduce cataract risk. Antioxidants for cataract prevention, like vitamins C and E, can help protect your eyes. Consider these foods to aid in cataract prevention.

• Vitamin C: Citrus fruits, bell peppers, and broccoli
• Vitamin E: Almonds, sunflower seeds, and spinach
• Leafy Greens: Kale and spinach, rich in lutein and zeaxanthin, help filter harmful blue light
• Carrots: High in beta-carotene and support healthy vision

Supplements: Do You Need Them?

If you can’t get enough vitamins through your diet, your ophthalmologist might recommend supplements for eye health. Always consult your doctor before starting any supplement regimen. More information on supplements for eye health can be found here.

Protect Your Eyes from UV Rays

Prolonged UV exposure can damage the delicate tissues of your eyes, leading to cataract formation. It’s important to use sunglasses for eye protection. Shop for sunglasses labeled with 100% UV protection, which blocks UVA and UVB rays. Other sun protection tips for eye health include wearing a wide-brimmed hat and seeking shaded areas during peak sunlight hours (10:00 am to 4:00 pm).

Regular Eye Exams: Your First Line of Defense

Annual eye exams for cataracts are important for prevention and early diagnosis. If you have higher risk factors due to age, family history, or medical conditions, your doctor may recommend more frequent eye exams.

Lifestyle Changes to Lower Cataract Risk

• Quit Smoking: Smoking increases oxidative stress, which damages your eye health.

• Limit Alcohol Consumption: Lowering your alcohol intake is an effective way to protect your eye health.

• Maintain a Healthy Weight: Obesity and diabetes are linked to cataracts.

• Manage Chronic Conditions: Uncontrolled blood sugar and hypertension can damage the small blood vessels in the eyes.

Eye Safety: Preventing Injuries That Lead to Cataracts

Trauma to the eye can cause cataracts to develop weeks or years after the injury. Protective eyewear is an easy, cost-effective way to prevent or lower the risk of injury.

• Sports: Use eyewear that is specific to your activity.

• Construction: Use safety glasses or visors.

• Home Projects: Safety goggles and glasses can help prevent accidents while working with tools.
