Coronavirus lockdown measures pose many problems for blind and visually impaired people. Will services become more stretched as hospitals and social care come under more pressure? How do you navigate shops which are occasionally bare when it comes to essentials? We hear the concerns of listeners - as Cathy Yelf of The Macular Society has definite advice for people with the condition - to not skip on your crucial, sight saving injections for fear of having to stay indoors. And a calming piece of relief from Coronavirus - we want to hear about the blind people of history who have led fascinating lives and intrigued you. We've already heard about Nicholas Saunderson, the blind boy from Barnsley who rose to the Lucasian Chair of Mathematics at Cambridge. That story has reminded one listener of a blind bell ringer who enchanted the people of Cambridge - and made a bit of money in the process.
