Most Common Causes of Cataract: What You Need to Know

What Is a Cataract?

A cataract is a cloudy area that forms in the lens of your eye. Because of this cloudiness, your vision may become blurry or faded. Cataracts are a leading cause of vision loss, especially in older adults. However, they can affect people of any age. Understanding the most common causes of cataract can help you protect your eyesight.

Why Do Cataracts Develop?

Many people wonder, “Why do cataracts develop?” Cataracts form when proteins in the lens of your eye break down and clump together. As a result, the lens becomes cloudy. This process often happens slowly over time. Although aging is the main reason, other cataract risk factors can also play a role. Knowing these causes can help you lower your risk.

Most Common Causes of Cataract

Several factors can lead to cataract formation. Below are the most common causes of cataract:

Aging: Most cataracts develop as people get older. The lens naturally changes with age, making cataracts more likely.

Diabetes: People with diabetes have a higher risk of cataracts. High blood sugar can damage the lens over time.

UV Exposure: Spending a lot of time in sunlight without eye protection can increase your risk. Ultraviolet (UV) rays can harm the lens.

Smoking: Smoking tobacco can speed up cataract growth. It also raises your risk for other eye problems.

Eye Injury: An injury to the eye can cause a cataract to form, sometimes years later.

Genetics: If family members have had cataracts, you may be more likely to get them too.

Certain Medications: Long-term use of steroids and some other medicines can increase your risk.

According to the World Health Organization (WHO), aging is the most common cause, but these other factors are also important.

Who Is at Risk?

Anyone can get a cataract, but some people are at higher risk. For example, adults over age 60 are more likely to develop cataracts. People with diabetes, those who smoke, and those with a family history of cataracts also face higher risks. In addition, people who spend a lot of time outdoors without sunglasses are at greater risk due to UV exposure. Knowing your risk can help you take steps to protect your eyes.

Prevention Tips

While you cannot stop aging, you can lower your risk of cataracts by making healthy choices. Here are some simple tips:

Wear sunglasses that block UV rays when outdoors.

Quit smoking or avoid starting.

Manage health conditions like diabetes with regular check-ups.

Eat a healthy diet rich in fruits and vegetables.

Limit alcohol use.

Protect your eyes from injury by wearing safety glasses when needed.

Following these steps can help keep your eyes healthy for longer.
