Education

Partial or total loss of sight affects millions of people worldwide. Many cases are preventable or curable, but simple interventions are not available in some poorer countries. The 15 video tracks in this album explore the impact of visual impairment and corrective treatments.  Derek Child explains how he learned to adapt to losing his sight and the training that helps him stay mobile and independent. Experts from Contamac reveal the science behind lens production. The Good Health Train brings basic health care to poor communities in rural South Africa, where locals live without access to treatments for common problems like cataract surgery.
