Many of us who live with impaired sight or blindness find that volunteering our time to help others with vision loss fulfils something in ourselves as well as assisting them. But not many of us do it on the scale of Dr. Andrew Bastawrous A British-Egyptian ophthalmologist who was that kid and later Decided to devote his skills to devising and delivering Eye care and treatment for the 1.1 billion people who don’t have access to eye glasses or treatment and who often live beyond the end of the road.

He went on to develop a cellphone system called Peek for testing eyes in impoverished communities across Africa.
