What causes Cataracts?

Cataracts are one of the leading causes of vision loss worldwide, yet many people are unaware of what causes them. While aging is the primary factor, several other elements can contribute to the development of cataracts. Understanding these causes can help you take steps to protect your vision and seek timely treatment.

The Ageing Process and Cataracts

The most common cause of cataracts is the natural ageing process. Over time, the proteins in the eye’s lens begin to break down and clump together, creating cloudy areas. This process typically begins after the age of 40 and progresses gradually, affecting vision in later years.

Medical Conditions That Increase Cataract Risk

Certain medical conditions can increase the likelihood of developing cataracts, including:

  • Diabetes: High blood sugar levels can accelerate the formation of cataracts.
  • Hypertension: Long-term high blood pressure can impact the health of the eye.
  • Obesity: Being overweight is a risk factor for several eye conditions, including cataracts.

Environmental and Lifestyle Factors

Your lifestyle and environment can also play a role in cataract formation. Key contributors include:

  • UV Exposure: Prolonged exposure to ultraviolet light can damage the lens over time.
  • Smoking: Tobacco use increases oxidative stress, which speeds up the breakdown of lens proteins.
  • Poor Nutrition: A diet lacking in antioxidants, like vitamins C and E, can leave the lens vulnerable to damage.
  • Alcohol Consumption: Excessive drinking is linked to a higher risk of cataracts.

Trauma and Injury

Eye injuries, surgeries, or long-term inflammation can also lead to cataract formation. Traumatic cataracts may develop immediately after an injury or years later, depending on the extent of the damage.

Medications and Cataracts

Long-term use of certain medications, such as corticosteroids, can increase the risk of cataracts. If you’re on medication, consult with your doctor about any potential side effects related to your vision.

Can Cataracts Be Prevented?

While some causes of cataracts are unavoidable, such as ageing, you can take steps to reduce your risk:

  • Wear sunglasses with UV protection.
  • Maintain a healthy diet rich in fruits, vegetables, and antioxidants.
  • Quit smoking and limit alcohol intake.
  • Manage chronic conditions like diabetes and hypertension.

Early Diagnosis and Treatment

Recognising cataracts early allows you to take control of your eye health. Regular eye exams can detect the condition in its early stages and help you plan for treatment when it becomes necessary.
