In this special programme, we examine the role genetics plays in both the inheritance of sight loss and its future treatment. We hear about the latest breakthrough reported in the journal 'Nature Medicine' in which the vision of a completely blind man was partially restored using light-sensing proteins first found in algae. He was treated with a type of therapy called optogenetics, which uses the proteins to control cells at the back of his eye.And we discuss the merits of gene testing with the Chief Executive of Retina UK about how genetic testing can help people with inherited sight loss make future choices about their lives.

New figures show there have been over 200 injuries and 1,100 complaints to local authorities since the trial of electric scooters began in 50 towns and cities across the UK. Sight loss charities are calling for stricter enforcement of existing regulations to keep people who are blind or visually impaired safe. And we speak to blind or visually impaired football fans as they make a welcome return to stadia.

The pandemic has accelerated our use of the digital world, meaning accessible websites and apps have never been more important. So who's doing it well and who could do better?We've been collating your examples of website accessibility and put them to Robin Christopherson from AbilityNet, who offer advice for companies and public bodies on making their online platforms suitable for people who are blind or visually impaired.Also - we review the latest software to be included on the Amazon Alexa and Google Home platforms. And Josh Gregg from the University of York talks about his project to make sure future technologies like augmented reality are designed with accessibility in mind from inception.
