Cataract is an ocular opacity, partial or complete, of one or both eyes, on or in the lens or capsule, especially an opacity impairing vision or causing blindness.
The subsequent cloudy appearance of the eye resulted in the origin of the name cataract.
Causes of cataract:
1. Age-related cataract: Most cataracts are related to aging.
2. Congenital cataracts: Some babies are born with cataracts or develop them in childhood, often in both eyes.
3. Secondary cataract: Development in people who have certain other health issues, such as diabetes or steroid use
4. Traumatic cataract: cataracts which develop after an eye injury
How to prevent cataract?
Intake of dietary antioxidants prevents cataract formation by blocking the oxidative modification of the lens.
Vitamins A, C and E are known to prevent cataract. Take these from the natural sources. Eating green leafy vegetables and fruits provides the best sources.
