because light reflects into the owl`s eyes, then it reflects, making it glow, only at night
The animal's eyes glow in the night.
Most animal's eyes glow in the dark because they are adapt to seeing at night. Human's eyes don't glow in the dark because we do not see at night as well.
dog
in the sims 2 pets, the dogs eyes do not glow, but through a camera lens in real life, they seem to glow a greenish white.
Yes. Coyotes eyes glow at night because their eyes are like mirrors. The small amount of light reflects against their eyes like a cats.
its from the little amount of light reflecting off the retna You mean retina? Just for the record, the "glow" come from a reflective layer behind the retina. The eyes themselves don't glow.
they glow when the light falls on their eyes... this is due to refraction they acts as IR camera to watch in dim light of night
Reflection.
Bats have eyes and can see both at night and during the day using their eyes. However bats do not rely on their eyes at night (in the dark), because they have another sense they use called "echo location" which works better than their eyes.
Tapetum lucidum
Well...I don't think any animal's eyes can just turn red at night. But, some animal's eyes DO turn color due to the lighting. Like dogs eyes glow in the dark so-to-say. If you turn into a right position, you can see the're eyes glow. It may seem like their eyes changed color.
