Dear followers, https://ift.tt/3K6kjab This may alienate some of you.You know how light doesn’t cease existing at night? You know how everything looks kind of grayscale though instead? Well for some people whose brain can better colorblend the RGB color their eyes perceive. Let me explain.The cones and rods in the human eyes are specially designed to see green, red, and blue with the exception of tetrachromatic and colorblind individuals. There are more green receptors than blue or red, as it is in the center of the color spectrum and humans need to be more sensitive to its presence. This also explains why these are the colors chosen for use in LED screens. Some people can see these colors dance in pitch black, as the light is more dispersed: they are purported as dots, specks, or spots. It’s just the brain unable to colorblend the eyes’ photoreceptor signals; however, they do accurately interpret the eye’s initial input. This phenomenon dissipates as access to unfiltered white light grows.I am one of the people who can see these dots. However, when I was sick with Sars-COVID-19, I was much more sensitive to my body’s experiences, and this one in particular, (the Tetris affect also kicks my ass when I’m sick). I started to see a green circle pulsate on the ceiling.I noticed that this was in the center of my field of vision. The pulsing was regular but with the highest peaks around the same time as my inhalations. [.gif does not pulsate perfectly in time] This circle was produced by my pupils dilating and contracting. I started to trace my eyes around the peripheral of my field of view, and the green traced behind microseconds after I moved my eyes.This leads me to believe that our eyes highlight the things we directly look at in green light to emphasize them in our working memory.Thank you for coming to my TEDtalk.
