Do you have red eyes? Or are they blue, brown or hazel? Regardless of the color of your eyes, you may occasionally appear to have red eyes in photographs.
Have you ever noticed that after having your picture taken, you look like an alien or a zombie with bright, glowing red eyes? This phenomenon is known as the “red eye effect.” Although it may seem magical and somewhat sinister, there is a logical scientific explanation for it.
So, what causes your blue (or brown or hazel) eyes to turn red in certain photos? The red eye effect occurs when flash photos are taken in low-light conditions. When the flash is positioned close to the camera lens (which is the case in most cameras), you may be looking directly at the flash when you look at the camera lens.
The red eye effect occurs because the flash’s light is too fast for the eye’s pupil to close. The intense light from the flash enters the eye through the pupil, reflects off the retina at the back of the eye, and exits back through the pupil. The camera captures this reflected light, which appears red due to the presence of blood in the back of the eye.
The red eye effect is more pronounced in individuals with light eye colors, light hair colors, and fair complexions. Scientists believe that this is because these individuals have less melanin in their eyes, which helps to mitigate the red eye effect to some extent in people with darker eyes, hair colors, and complexions.
If you have pets, you may have noticed that the red eye effect can manifest differently in animals. Animals have a special reflective layer called the tapetum at the back of their eyes. The tapetum aids in enhancing night vision and can result in a blue, green, or yellow eye effect, depending on the animal.
