Understanding Charles Bonnet Syndrome

Charles Bonnet syndrome (CBS) is a common condition among people who’ve lost their sight.

It causes people who have lost a lot of vision to see things that aren’t really there – medically known as having a hallucination.

CBS hallucinations are only caused by sight loss and aren’t a sign that you have a mental health problem.

This page contains a summary of our information on CBS. To read our full information, download our Understanding Charles Bonnet syndrome guide, which is accredited by the Royal College of Ophthalmologists:
