Cataracts
A cataract is defined as a progressive opacity or clouding of the eye lens that eventually leads to blindness. Affected people feel like they are looking through a fog that becomes increasingly denser
- The causes of cataracts are not entirely understood.
- Most cataract cases occur at an older age and are caused by metabolic disorders and the ageing of body tissues.
- Cataracts can also be congenital or hereditary (e.g. due to rubella during pregnancy).
- Additional risk factors include: injuries, other eye diseases, ultraviolet radiation, smoking, and diabetes.
