What eye health care does he and the foundation do?

The foundation mainly focus on cataract blindness because half of the global blindness is caused by cataracts – a clouding of the lens of the eye that can be treated by a simple surgical procedure – and the World Bank has identified cataract surgery as one of the most cost-effective of all public health interventions. They also tackle other causes of blindness, including trachoma and refractive error.
