Imagine receiving the results of a hospital scan on a letter you can't read, a final demand for payment of a bill you haven't seen or trying to decipher the dosage for your medicine.
Blind and partially sighted people should not have to ask others to read them information that they would prefer to keep private - but many have no choice.
Imagine the embarrassment of having to rely on others, simply because the information is not accessible to you. Imagine the frustration and angst caused by unnecessary worry.
The depressing reality for nearly two million people with significant sight problems is that inaccessible information has a devastating impact on their health and sense of security.

How we help
RNIB's services help the health industry to make information accessible to blind and partially sighted patients. Patients can call RNIB's Medicine Leaflet Line to receive information in accessible formats, thanks to the X-PIL service that we have developed with industry.
We are campaigning for the NHS to stop giving blind and partially sighted people their health information in ordinary print - and we are seeing results.
We promote the Equality Act so blind and partially sighted people can get the information they need, and help blind and partially sighted people to know their legal rights and obtain the information they are legally entitled to.
