Have you ever wondered why sometimes, when we take a picture, our eyes get red? Why is that happening? Is there a specific reason why the colour is red and not, let’s say, blue?
Well, it seems there is and it all has to do with the anatomy of the human body. The red eye is actually caused by the blood vessels of our eyes!
When we take a picture with a flash that’s too close to our eyes, the light reflects off the blood vessels at the back of our eye. We don’t see them normally because our normal lighting is too dim to light up the inside of our eyes but, the flash on a camera is bright enough to light it up and have it come back out.

The red eye effect is more often caused in darker environments and, the more open your pupils are, the more red eye effect you get in your photos.
