How to Prevent Cataracts: Tips for Maintaining Clear Vision

Cataracts are one of the leading causes of vision loss, especially as we age. Fortunately, there are steps you can take to help prevent or delay their development. At Shepard Eye Center, we believe that proactive care and education are essential in preserving your sight.
 

What Are Cataracts and How Do They Develop?

A cataract occurs when the clear lens of the eye becomes cloudy, leading to blurry vision, increased sensitivity to light, and difficulty seeing at night. The lens sits behind the iris and focuses light onto the retina. As we age, the proteins in the lens can begin to break down and clump together, forming cloudy areas—this is the beginning of a cataract.
 

While aging is the most common cause, other risk factors include:
 

• Diabetes
• Prolonged exposure to UV radiation
• Smoking
• Alcohol consumption
• Eye injuries or surgeries
• Long-term use of steroid medications

Lifestyle Changes to Help Prevent Cataracts

• While not all cataracts can be prevented, certain lifestyle habits can lower your risk or delay progression:
• Protect Your Eyes from UV Light: Wear sunglasses with 100% UVA and UVB protection and a wide-brimmed hat when outdoors. UV radiation can accelerate cataract formation.
• Maintain a Healthy Diet: Eat a diet rich in antioxidants such as vitamins C and E, lutein, and zeaxanthin. Leafy greens, citrus fruits, nuts, and colorful vegetables are great options.
• Quit Smoking: Smoking increases the risk of cataracts by altering the cells of the lens through oxidative stress. Quitting reduces this risk significantly over time.
• Limit Alcohol Intake: Heavy alcohol consumption has been linked to cataract formation. Moderation is key.
• Manage Health Conditions: Conditions like diabetes increase the risk of cataracts. Keeping blood sugar levels under control can help protect your vision.
• Schedule Regular Eye Exams: Comprehensive eye exams can detect early signs of cataracts and other vision issues, even before symptoms appear.

Recognizing the Early Signs of Cataracts

Recognizing the early symptoms of cataracts can help you seek treatment at the right time. Watch for:
 

• Blurred or cloudy vision
• Glare or halos around lights
• Increased sensitivity to light
• Frequent changes in prescription glasses
• Difficulty seeing at night
• Faded or yellowed colors

If you’re noticing any of these changes, it’s important to schedule an eye exam.
 

When Is It Time to Consider Cataract Surgery?

Cataract surgery is typically recommended when your vision begins to interfere with your daily life—driving, reading, or enjoying hobbies becomes difficult, even with updated glasses. Cataract surgery is a safe and highly effective procedure that replaces the cloudy lens with a clear artificial lens, restoring sharp vision. Our experienced ophthalmologists will assess your symptoms, overall eye health, and lifestyle to determine the right time for surgery.
