“A doctor can easily diagnose a tumor of children age only by seeing a photograph.”

That’s right.

When a flash photo of a human being is taken, the light will reflect from their eyes in such a way as to cause “red eye”, reflection of blood vessels which are red. However, in a child with an eye tumor, the light will reflect back like a cat’s eye, this “white reflection” is known as “white reflex”. This is actually due to the destruction of the blood vessels in the eye.

So next time if you ever see a photograph like the one shown here; let the person know to see a doctor.
