As people age, the risk of developing cataracts increases due to the natural aging process and prolonged exposure to UV damage.
Lifestyle choices can increase the risk of cataracts – smoking, excessive alcohol consumption and poor nutrition.
Eye injuries, including blunt trauma or exposure to harmful substances, can contribute to the development of cataracts.
People who have diabetes and hypertension, or obesity, may be more prone to cataracts at a younger age.
If the cataract is in one eye only, then the effects may not be noticed until the cataract has progressed. Affects that may be noticed include difficulty reading, recognising faces, driving or watching television and their vision may be worse in bright light. Some people experience double vision and see haloes.
