Common Eye Disease Can Cause Hallucinations, But Few People Know It

Charles Bonnet Syndrome, a condition affecting people with significant vision loss, can cause vivid hallucinations of people, flowers, and patterns. Experts emphasize these visual experiences are harmless side effects, not signs of mental illness or dementia. The hallucinations occur because the brain compensates for lost visual input by generating images on its own. Understanding this phenomenon is crucial for patients and healthcare providers to avoid misdiagnosis and unnecessary psychological treatment. Awareness of this common but underrecognized condition can help reduce patient anxiety and improve quality of life for those experiencing vision loss.
