16-year-old Grace Marsh talks of her vision loss and her poetry aspirations. Actor Karina Jones lands an iconic role as a blind character.

21-year-old Allan Hennessey was born in Iraq totally blind. His parents applied to the UK for him to undergo laser surgery, which restored a minimal amount of vision in one eye. Later Allan and his family settled in the UK on a council estate in east London. While attending a mainstream school, he rejected all attempts to teach him to read braille or adapt to his visual impairment, preferring to rely on the support and safety net of the multicultural community in which he thrived. In high school, he was sent to a school for blind children, which he found claustrophobic and soon left. He lost his way academically in the middle years of high school and then, on a whim, decided to try for Cambridge. Allan has this year graduated with a 1st class Honours degree in law and plans to be a barrister - and he still uses no adaptations - we ask him why.

On the 21st of August, there will be a total solar eclipse in the US. This is being touted as a 'once in a lifetime' opportunity and it seems visually impaired people are not to miss out. NASA has sponsored the making of a tactile book depicting the different stages of the eclipse. There is a smartphone app people can try that allows the user to trace their finger over a picture of the eclipse, and the phone will play a sound or vibrate according to the intensity of the lightness shown on the screen. Harvard University has been working on a project to stream the sound of the eclipse to visually impaired people over the internet from Wyoming, one of the14 states with a ringside view of it. We speak to Allyson Bieryla from Harvard University about the project.

And finally, we ask Virgin Media whether they really meant to send out a form for visually impaired people to have their doctor fill out declaring their visual impairment before they could receive their bill in braille.

In August 2016 it became mandatory for health and social care providers to offer patients written information in whichever format they required - whether that be via text, email, braille, audio or large print. The implementation of what is called the Accessible Information Standard has recently been reviewed with mixed results. We put some listeners' experiences of getting required information in a required format from the NHS to Olivia Butterworth from NHS England.

Peter White talks to Vanessa Potter about her book, Patient H69 about her experience of losing her sight over 72 hours, and what it was like learning to see again.

What's the best approach when it comes to holidays for blind and partially sighted people? TravelEyes is a company which takes both blind and sighted people on holiday - the visually impaired traveller pays full price, and the fully-sighted person pays up to 50% of the full cost and agrees to guide and describe the attractions for the visually impaired travellers. But what if you have an additional need like a hearing impairment? The travel company says that in some cases, customers who have an additional need will have to take someone along as a carer. Peter White speaks to the company's founder Amar Latif about this policy.
