Fun Fact of the day

 


The stars and flashes of light you see when you rub your eyes are called "phosphenes."

Rubbing your eyes a little too hard might leave you seeing stars—which are actually phosphenes, according to Troy Bedinghaus, OD, of Verywell Health. "The optic nerve translates this pressure into various images," Bedinghaus says. "Pressure phosphenes can remain for a few seconds after the rubbing stops and the eyes are opened, allowing the phosphenes to be seen."
