What do you see at night?

The color of the eyes doesn't have much to do with your ability to see in the dark but the type, number, and location of your photoreceptors does. In the back of your eye you have two kinds of photoreceptors, rods and cones. Rods see better in low light conditions and see more in black and white. Cones see better in bright light conditions and give us our color vision. When the light that focuses on the back of the eye lands mostly on cones, such as in humans, we are adapted to daytime seeing. Animals that are nocturnal, i.e. active at night, have more rods in the back of their eyes where the light focuses. Here's a trick though, our rods on on the periphery of the back of our eye. When you want to see something better in the dark, look at it from the corner of you eye and it will be easier to see because it will be focused more on your rods.
