Red eye is caused by light reflecting off the retina at the back of your eyes. Generally, it happens in low light conditions when a flash is used. The bright light flashes so quickly that eyes don’t have time to respond and restrict the pupil so that less light enters the eye. This is why “red eye” happens.
Why do people’s eyes turn red in pictures?
As your camera’s flash goes off, the pupil doesn’t have time to react, and the light causes a reflection on the retina which bounces back to the camera. There’s a layer on the back of the eye called the choroid which is full of blood causing the reflection color to be red.

Can you really have violet eyes?
Violet is an actual but rare eye color that is a form of blue eyes. It requires a very specific type of structure to the iris to produce the type of light scattering of melanin pigment to create the violet appearance. Blue eyes are a recent arrival in human history.
Do adults have a red reflex?
The most common cause of this dulling in an adult is a cataract, but an abnormal red reflex may also clue you in to other pathologies in the cornea (abrasion, infection, or scar), vitreous (hemorrhage or inflammation), or retina (retinal detachment).

What is the rarest eye Colour?
The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer. Eye color isn’t just a superfluous part of your appearance.
What are the 3 rarest eye colors?
The Rarest Eye Colors and How They Occur Eye Color Cause(s) Violet Lack of melanin mixed with light reflecting off of red blood vessels. Grey Very little melanin with a high amount of collagen in the stroma. Green A little melanin, a large amount of lipochrome, and Rayleigh scattering of light.
Do people have GREY eyes?
Less than 1 percent of people have gray eyes. Gray eyes are very rare. Scientists think gray eyes have even less melanin than blue eyes. Gray eyes scatter light differently, which makes them pale.
How do you fix red eyes without eye drops?

What age do you stop checking red reflex?
For the well-baby check up at 1 month, check for the red reflex. For visits from 2 to 18 months of age, in addition to the red reflex, you need to check for the corneal light reflexes and ocular mobility, as well as to perform cover- uncover tests.

How do you know if you have a red reflex?
