I had an interesting question on colour filter overlays from a librarian today.

A dyslexic student wants to read some original documents, not scans or reproductions, and they'd like to put some colour filter overlays on them.

The librarians are concerned that the documents might get damaged. They want to know if a hand-held colour filter, or something on the light source, would work just as well.

I don't know much about the science of colour filters for dyslexia except I've heard the data on efficacy is mixed, but assuming we want this to happen: is there any strong reason to have the colour filter directly on the document?

I don't know any hashtags that archives people would be watching, so please recommend one if you know one!
