Experiences include a darkening of the visual field that moves against the rubbing, a diffuse colored patch that also moves against the rubbing, well defined shapes such as bright circles that exist near or opposite to where pressure is being applied,[7] a scintillating and ever-changing and deforming light grid with occasional dark spots (like a crumpling fly-spotted flyscreen), and a sparse field of intense blue points of light. He says that, when the phosphenes or flashes are created without any movement, and are not predictable, THEN they are dangerous, because this type of flashes are created by something inside the eye (like a retinal tear) and not by the movement of the eye.

[14], Experiments with humans have shown that when the visual cortex is stimulated above the calcarine fissure, phosphenes are produced in the lower part of the visual field, and vice versa.[15]. … The meaning and differences between phosphenes and photopsies are often confused. Electromagnetic waves emitted by everyday electronic devices (phones, radios, walkie-talkies, Wi-Fi, Bluetooth…) belong to the category of radiofrequency waves, or radio waves.If you are looking for a detailed, scientific explanation of electromagnetic waves and their characteristics, please refer to our recently published article.

These lights are called magneto-phosphenes and are believed to arise from direct stimulation the retina by magnetic-field induced currents. [6] A version of this theory has been revived, except, according to its author, that "phosphene lights are [supposed to be] due to the intrinsic perception of induced or spontaneous increased biophoton emission of cells in various parts of the visual system (from retina to cortex)"[24], In 1988, David Lewis-Williams and T. A. Dowson published an article about phosphenes and other entoptic phenomena. Phosphenes have been created by electrical stimulation of the brain, reported by neurologist Otfrid Foerster as early as 1929. Scientists are moving closer to creating a technology that will restore vision for the blind, thanks to a team of Dutch researchers who successfully built an implant that bypasses the eyes and allows monkeys to perceive artificially induced patterns in their brains. In some cases, when the light rays are abundant and disturb the vision, you can clean the vitreous humor, better known as vitrectomy. Low blood pressure, low oxygenation or a lack of glucose are most common causes of metabolic stimulation. It is possible these involve some mechanical stimulation of the retina, but they may also involve mechanical and metabolic (such as from low oxygenation or lack of glucose) stimulation of neurons of the visual cortex or of other parts of the visual system.
