Why do I see fractals when I rub my eyes?
Eleonora Lad, an associate professor of ophthalmology at Duke University Medical Center who has a background in neuroscience, explains exactly why eye rubbing generates these visions: “Most vision researchers believe that phosphenes result from the normal activity of the visual system after stimulation of one of its …
What causes green vision?
Chromatopsia is caused by drugs, intense stimulation, or snow blindness, and it can occur after eye hemorrhages, cataract extraction, electric shock, or optic atrophy. There are several forms: erythropsia (red vision), chloropsia (green vision), xanthopsia (yellow vision), and cyanopsia (blue vision).

What happens to your eyes when you change the shape of vision?
One, you deform the retina a little bit and this makes the photoreceptors, which are the specialised rod and cone cells that pick up photons of light, change their pattern of firing activity in response, which is how we see.
What do you see when you Close Your Eyes?
Today I found out what the things you see when you close your eyes and rub them hard are called, namely “phosphenes”. A phosphene is characterized by perceiving some form of light when there is little or no light actually entering the eye, making it an entopic phenomenon (meaning the source of the phenomenon is within the eye itself).
