RNIB has relaunched its web site to bring it up to the accessibility standards the charity expects of other organisations.
Margaret O'Donnell, web manager at RNIB, said: "We campaign for good web design, saying accessible web sites can be dynamic, but ours didn't have as much of this as we'd have liked. There was no customer focus in terms of what audience there might be, or how they used the site."
The new site contains hidden features that make it easier for text-to-speech software to read. Its colours can be changed and it is designed for better viewing with screen magnifiers.
This month RNIB began legal action against firms it says are ignoring the needs of blind and partially sighted people accessing their web sites.
