Magnetophosphene

Magnetophosphene is a phenomenon characterized by the perception of light caused by the application of magnetic fields to the head. This phenomenon is not caused by light entering the eye, but rather by the magnetic field itself.

Overview

Magnetophosphene is a type of phosphene, which is a phenomenon of seeing light without light actually entering the eye. The term "magnetophosphene" specifically refers to phosphenes caused by magnetic fields.

The phenomenon was first described in the 20th century, when people working in high magnetic fields reported seeing flashes of light. These flashes were later identified as magnetophosphenes.

Causes

Magnetophosphenes are caused by the application of magnetic fields to the head. This can occur in various situations, such as during MRI scans or when working in environments with high magnetic fields.

The exact mechanism of how magnetic fields cause magnetophosphenes is not fully understood. However, it is believed that the magnetic fields induce electrical currents in the retina, which then stimulate the cells responsible for vision.

Symptoms

The main symptom of magnetophosphene is the perception of light, often described as flashes or flickers. These can vary in intensity and duration, depending on the strength and duration of the magnetic field.
