Because your obviously the spawn of evil.

But seriously it's called the red eye affect and it happens because the light of the flash occurs too fast for the pupil to close, so much of the very bright light from the flash passes into the eye through the pupil, reflects off the fundus at the back of the eyeball and out through the pupil. The camera records this reflected light. The main cause of the red color is the ample amount of blood in the choroid which nourishes the back of the eye and is located behind the retina.

The blood in the retinal circulation is far less than in the choroid, and plays virtually no role. The eye contains several photostable pigments that all absorb in the short wavelength region, and hence contribute somewhat to the red eye effect.[1] The lens cuts off deep blue and violet light, below 430 nm (depending on age), and macular pigment absorbs between 400 and 500 nm, but this pigment is located exclusively in the tiny fovea. Melanin, located in the retinal pigment epithelium (RPE) and the choroid, shows a gradually increasing absorption towards the short wavelengths.

But blood is the main determinant of the red color, because it is completely transparent at long wavelengths and abruptly starts absorbing at 600 nm. The amount of red light emerging from the pupil depends on the amount of melanin in the layers behind the retina. This amount varies strongly between individuals. Light skinned people with blue eyes have relatively low melanin in the fundus and thus show a much stronger red-eye effect than dark skinned people with brown eyes. The same holds for animals. The color of the iris itself is of virtually no importance for the red-eye effect.

This is obvious because the red-eye effect is most apparent when photographing dark adapted subjects, hence with fully dilated pupils. Photographs taken with infrared light through night vision devices always show very bright pupils because, in the dark, the pupils are fully dilated and the infrared light is not absorbed by any ocular pigment.

The role of melanin in red-eye effect is demonstrated in animals with heterochromia: only the blue eye displays the effect. The effect is still more pronounced in humans and animals with albinism. All forms of albinism involve abnormal production and/or deposition of melanin.

Depends on the lighting and camera used, these look older so I would assume the low light and flash close to the camera.

It's not just blue eyes it's the way the light enters the eye. Blue eyes have less pigment so it's more visible but with the right angles any eyes can have red light (eyes)

yep, you're a demon. kidding. it's because of the close flash being reflected off your eye. the red is the blood behind your eye. or you could be a demon

Not 100% sure but it may be to do with the blue pigment in the eye means if the flash is slightly more green then it makes the red show and it could also be blue eyes are more transparent meaning the blood at the back or the eye is shown

Ephemera1 · Answer

All eyes could go red in pictures. Has nothing to do with them being blue. It's how flash and the lens work.

Psychlopic · Answer

It's a reflection from the inside of your eyes through the pupils. You can only really get red eyes with a flash, and in a somewhat dark room. Iris color is irrelevant, but pupil size does.

cupidkisses · Answer

Eyes look red in photos due to the rich blood supply of the choroid, a layer of connective tissue at the back of the eye that nourishes the retina and gives it its normal red color.

Anonymous · Answer

The pupils are very dilated from the low light and the flash is reflecting back the color of the back of the eyeball.

Angle of light or something. Mine are brown and still get red sometimes.
