Final answer:
Cataracts are a clouding of the lens in the eye that can cause vision loss. Aging, UV-B exposure, medical conditions, smoking, eye injuries, prolonged use of corticosteroids, genetics, and poor nutrition are 8 causes of cataracts.
Step-by-step explanation:
Cataracts are a clouding of the lens in the eye that can cause vision loss. Here are 8 causes of cataracts:
- Aging: Cataracts are more common in older individuals, with 60% of people between the ages of 65 and 74 developing cataracts.
- UV-B exposure: Repeated exposure to UV-B radiation, especially in equatorial regions, can increase the risk of cataract formation.
- Medical conditions: Diabetes, high blood pressure, and obesity are some conditions that can increase the likelihood of developing cataracts.
- Smoking: Smoking has been linked to an increased risk of cataracts.
- Eye injuries: Trauma to the eye can lead to the development of cataracts.
- Prolonged use of corticosteroids: Long-term use of certain medications like corticosteroids can increase cataract risk.
- Genetics: Some people may inherit a predisposition to developing cataracts.
- Poor nutrition: Nutrient deficiencies, such as low intake of vitamins A and C, may contribute to the development of cataracts.
