Causes of Cataracts

Cataracts occur when the natural lens of the eye becomes cloudy. This can happen due to a number of different causes, including:

1. Age: Cataracts are most commonly associated with aging. As people get older, the proteins in the lens of the eye can start to break down, causing it to become cloudy.
2. Genetics: Some people may be more prone to developing cataracts due to their genetic makeup.
3. Injury: Trauma to the eye can cause cataracts to develop. This can include blunt force trauma, such as being hit in the eye, or exposure to radiation.
4. Medications: Certain medications, such as corticosteroids and some cholesterol-lowering drugs, have been linked to cataract development.
5. Diseases: Some diseases, such as diabetes and high blood pressure, can increase the risk of developing cataracts. Additionally, conditions such as uveitis (inflammation of the eye) and retinitis pigmentosa (a genetic disorder that causes degeneration of the retina) can also lead to cataracts.
6. Lifestyle factors: Smoking, excessive alcohol consumption, and prolonged exposure to sunlight without eye protection have all been linked to an increased risk of cataract development.
