Mirror phenomenon — Concentric halos around eyes in a foggy bathroom

[QUOTE="Samimnot, post: 6271158, member: 670918"] Here is some information that may shed light on the subject. It lies in the realm of anatomy. Have you ever witnessed the reflection from a cat's eye at night? It is due to the micro-spherical shape of each eye cell, as well as a macro-spherical shape of the inner eye-cavity. Light which enters the eye, scatters in a spherical pattern, towards the light source/observer because of both, the micro and macro structures of the eye. The former is like reflective beads on a projector screen or road paint. The second is like the secondary mirror on a reflector-type telescope. In a foggy room, this complex light-scattering effect would tend to produce a uniform glow emanating from the pupil, almost like a hologram of the inner eye, as opposed to a point-source. This hologram-like light pattern can illuminate the inner eye, and the area of fog around the pupil, from the perspective of the viewer or camera. In humans, this reflection is attenuated by retinal pigments. But if the incident light is strong enough, or the person has very fair complexion, eye-reflections can be bright enough to see, and bright enough to illuminate the area around the eye. [/QUOTE]
