What Causes Cataracts?
July 14, 2023 | by Yashaswi Pathakamuri | Posted in FAQ's
Cataracts are a common eye condition characterized by the clouding of the lens, a transparent structure located behind the iris. The exact cause of cataracts is not fully understood, but several factors can contribute to their development. These include:
- Aging: Age-related changes in the lens are the most common cause of cataracts. As you grow older, the proteins in the lens may start to clump together and form cloudy areas, leading to the development of cataracts.
- Exposure to Ultraviolet (UV) Radiation: Prolonged exposure to UV radiation from sunlight or other sources, such as tanning beds, can increase the risk of developing cataracts. Protecting your eyes with sunglasses that block UV rays can help reduce this risk.
- Diabetes: People with diabetes are at a higher risk of developing cataracts. High blood sugar levels can cause changes in the lens that contribute to cataract formation.
- Smoking and Alcohol Consumption: Smoking and excessive alcohol consumption have been linked to an increased risk of cataracts. The exact mechanisms are not well understood, but they may involve oxidative stress and damage to the lens.
- Certain Medications and Medical Conditions: Prolonged use of certain medications, such as corticosteroids, can increase the risk of cataracts. Additionally, certain medical conditions like obesity, high blood pressure, and previous eye injuries or surgeries can also contribute to cataract development.
- Genetic Factors: In some cases, cataracts can be inherited or caused by genetic mutations that affect the structure and function of the lens.
- Eye Trauma: Severe eye injuries or trauma can cause cataracts to develop. This can occur immediately after the injury or even years later.
It’s important to note that while these factors are associated with cataract development, the exact cause can vary from person to person. Regular eye examinations and consultation with an eye care professional can help diagnose and manage cataracts effectively. If cataracts significantly affect your vision and quality of life, surgical removal of the cataract may be recommended.
