Hallucinations are where you hear, see, smell, taste or feel things that appear to be real but only exist in your mind. Get medical help if you or someone else have hallucinations.
What eye condition causes hallucinations?
Summary. Charles Bonnet syndrome refers to the visual hallucinations caused by the brain's adjustment to significant vision loss. It occurs most often among the elderly who are more likely than any other age group to have eye conditions that affect sight, such as age-related macular degeneration.
It is estimated that 50-60% of people suffering from severe visual loss will experience visual hallucinations. These visual hallucinations seem to abate after a while, usually after 18 months for 60% of patients. The visual hallucinations are a purely visual symptom and are not due to any mental health problem.

Hallucinations refer to the experience of sensing things that seem real but do not exist.
During a hallucination, you may see, hear, feel, smell, or taste things that are not there—meaning they have no external source.
There are many possible causes for hallucinations, including mental health disorders, physical conditions, sensory problems, and drug use or withdrawal. Treatment methods will depend on the cause of the hallucinations and can range from medicine and therapy to lifestyle changes, like cutting back on alcohol and eliminating drug use.
