Food for thought!
From, Front Projection for "2001: A Space Odyssey" by Herb A. Lightman
from American Cinematographer:
"One stunnng effect that invariably brings gasps from the audience was achieved quite unexpectedly and may be regarded as a sort of "bonus" to the production. During the prologue a lithe leopard is seen moving among the rocks. As the big cat turns its head full into camera its eyes seem literally to light up with a brilliant, fluorescent orange glow. The impact is startling.
"A happy accident," shrugs Kubrick. "I can only conjecture that the cat's eyes must contain some substance having a reflectivity similar to that of the 3M material used on our screen, because the eyes picked up the front-projected light and reflected it almost as brightly as the screen itself.'' "

All eyes reflect light well because the path for light always works in both directions. In other words, if incoming light is focused by the cornea lens and forms a tiny bright spot on the retina... then that tiny bright spot can send light out through the cornea-lens, and beam it back to the original source.

In the movie "Big Fish" when Ed is dying in the hospital, his son watches him in anguish and there is only one light reflected in each of Will's and Ed's eyes. When Ed's eyes become fixed, the light in his eyes brightens, and a second light can be seen reflecting in the corner of his eyes. When the camera pans back to Will, two spots of light are now reflected in his eyes showing the addition of a second light off camera.
