    A fact sheet on Charles Bonnet syndrome (CBS).

    Charles Bonnet Syndrome is a term used to describe a situation where mentally healthy people with significant vision loss have vivid, recurrent visions.

    The simplest explanation for CBS is that when vision is lost, your brain isn’t receiving as many pictures. So your brain releases new fantasy pictures, or old pictures that it has stored, and you experience them as though they were real.

    The fact sheet is free to download or order.

    It is also available as an audio CD.
