Although current technology simplifies capturing art shots, the "red eye" effect is still the cause of ruining many of your beautiful pictures. Bright Side decided to investigate the cause of this "strange" effect.
In ambient light, you often have to open your eyes to allow light to enter. When the flash light hits your eyes, you won't have enough time to squint your eyes. Therefore, the amount of strong light from the lamp makes the scene light up and directly affects the eyeball, passing through the pupil to the rear blood vessels, reflecting red blood vessels on the veins. When the camera flash lights up reflecting this blood vessel, our eyes often have a "red" effect on the image.

High-quality effects often appear on the human eye and animal eyes, especially in the eyes of nocturnal animals - the retina has a special reflective layer called the tapetum lucidum mirror that acts as mirror placed behind the eyes. This tissue helps animals see things better at night with actions like reflectors (retroreflector) , taking reflected light and directly reflecting it back to its original direction.
