Mum, Dad, David and I are walking through London from Moorfields Eye Hospital to the London Eye. We are very grateful to Moorfields Eye Hospital for saving my mum's sight. Moorfields Eye Charity supports the incredible work of Moorfields Eye Hospital making a difference for patients like my mum and for people with sight problems around the world. We want to raise money to help the hospital provide the best possible care for its patients and support research to develop new treatments for blinding diseases.
