Concept and production 
Vision On was conceived and developed by BBC producers Ursula Eason and Patrick Dowling to replace a monthly series For the Deaf, a programme paced slowly enough for children to read captions and subtitles. It was noted in surveys that a favourite for deaf children was Top of the Pops, due to its lively and fast-moving format and the fact that even the profoundly deaf could still enjoy the music's lower frequency notes.
There was initial disagreement as to whether lip-reading or British sign language would be more appropriate. Eventually it was decided that, since the new programme was intended as entertainment rather than education, communication would be entirely visual, the amount of text would be severely limited and, except for a few repeated statements, speech would be abandoned altogether. The title Vision On referred to the illuminated sign in studios indicating that cameras were live. Normally another sign "Sound On" would follow, but the titles for Vision On deliberately omitted this. The programme's logo is made up from the words of the title and its reflection.
The aim of the programme was to entertain but also to encourage imagination, with a fast-paced flow of contrasting ideas, both sane and silly. This mixture was an apparent success as the series ran for twelve years and, while retaining a commitment to the deaf, attracted a wider following and gained several awards including the international Prix Jeunesse and the BAFTA Award for Specialised Programmes.
A full list of contributors can be found, but the main presenters were:
- Pat Keysell: an actress who also taught deaf children
- Tony Hart: artist, who made pictures in a variety of sizes and media, and encouraging children to submit their own paintings to "The Gallery", which they did in their thousands
- Ben Benison and Sylvester McCoy: mime artistes
- Wilf Lunn: eccentric inventor of equally eccentric machines
- David Cleveland: appeared in film sequences as the Prof
Besides the scenes with Hart, Keysell and the others doing artwork (which in later years appeared on the screen as the artwork being made without any hands), Vision On had many memorable segments:
- "The Gallery" – A section consisting of artwork sent into the show by viewers, with the name and age of the artist being shown alongside the artwork. Often the artwork shown on a specific show coincided with the theme of the show. At the end of this segment, Keysell would thank everyone for sending in their pictures, and apologize for being unable to return them.
- "The Burbles" – A couple of unseen people living inside a grandfather clock who converse in speech bubbles, mainly telling puns. Occasionally they are heard speaking the lines as if they are underwater, but other times there are just the speech bubbles.
- "The Prof" – A man in a white lab coat (aka film-makers David Cleveland, Tony Amies and David Wyatt) who is usually outdoors doing various humorous things.
- "Humphrey the Tortoise" – Much like the Burbles, Humphrey talks of something specific (usually a pun or joke) either to himself or someone else. His speech, as well as the other persons if there is one, is shown on screen with no audio.
- "The Digger" – A "cut-out" cartoon man designed and animated by Bill Mather and George Dunning. Each week on a construction site he digs into the dirt with a shovel until something interesting is dug up.
- "The Animated Clock" – An animated cuckoo clock that is either showing signs of trouble or whose parts come to life like a human being.
- "The Fuzzy Worm" – One running gag in later episodes involved one of the cast members frantically chasing a fuzzy worm trying to catch it to no avail and occasionally messing up the artwork of Hart and Keysell.
Despite its intended hearing-impaired audience, the show made extensive use of music for the benefit of hearing viewers watching the show. Notable themes included:
- The opening theme was "Accroche-Toi, Caroline" by Caravelli (recorded by the Paris Studio Group).
- The closing theme was "Java" in the versions recorded by Al Hirt and Bert Kaempfert
- "The Gallery" – "Cavatina" originally, but "Left Bank Two" by Wayne Hill (recorded by The Noveltones) is best remembered for this sequence. When Take Hart started, "Left Bank Two" became the opening theme tune and Cavatina became the "Gallery" music for the show instead.
- "The Burbles" theme "Goofy" by Cliff Johns.
- "Humphrey the tortoise" theme "Merry Ocarina" by Pierre Arvay.
- "Animated Clock" scene used "Gurney Slade" by Max Harris (the theme from the TV series The Strange World of Gurney Slade)
The programme was shown in many other countries, including France, Australia and New Zealand.
In the USA many PBS stations, and a few commercial stations, aired Vision On during the 1970s. Some of these stations, such as KOMO-TV in Seattle, taped their own episodes, which were seen along with the BBC-produced shows.
In eastern Canada episodes were often shown on TVOntario, which could also be seen in the north-eastern US.
End of production 
Series' producer Dowling eventually found that the flow of new ideas became more and more difficult to sustain, and after twelve years decided to close the programme while it was still at its height.
Dowling and Hart continued to make arts programmes, starting with Take Hart (which kept "The Gallery" segment), continuing with Hartbeat during the 1980s and 1990s, and then the BBC's current children's art programme, SMart.
