What Is The Main Cause Of Cataracts?

Cataracts develop when the clear lens in the eye becomes cloudy, leading to vision impairment. The main cause of cataracts is aging, which results in the breakdown and clumping of proteins within the lens. This process gradually clouds the lens, obstructing the passage of light and causing vision to become blurry or dim.

However, age isn't the sole factor contributing to cataract formation. Various other factors can accelerate or exacerbate the development of cataracts. – Dr Cm Chopra

UV Radiation: Prolonged exposure to ultraviolet (UV) radiation from sunlight or other sources can increase the risk of cataracts.
Diabetes: Individuals with diabetes are at a higher risk of developing cataracts due to elevated levels of blood sugar, which can cause damage to the lens.

Smoking: Smoking has been linked to an increased risk of cataracts, likely due to the harmful chemicals in cigarette smoke causing oxidative stress on the lens.
Genetics: Genetic factors can predispose certain individuals to cataracts, making them more likely to develop the condition earlier in life or with greater severity.

Eye Trauma or Injury: Trauma to the eye, such as blunt force trauma or penetrating injuries, can accelerate the development of cataracts.
Medications: Long-term use of certain medications, such as corticosteroids or statins, has been associated with an increased risk of cataracts.

Other Health Conditions: Certain health conditions, such as obesity or high blood pressure, can contribute to cataract formation.

While cataracts are primarily age-related, addressing modifiable risk factors such as UV exposure, smoking, and maintaining overall health can help reduce the likelihood of developing cataracts or slow their progression. Regular eye exams are essential for early detection and timely intervention to preserve vision and maintain overall eye health.
