"Blue eyes don't work at night they don't have enough cone receptors to take in dim light. Brown eyes are superior for night vision."
I have not heard this before! Interesting. I remember reading that males have better night vision then females, though females have a better sense of smell. Though we all knew that! I have blue eyes and see very well at night.
I looked it up, it appears to me that cone cells are for color and rod cells are for night vision.
The retina contains two forms of photosensitive cells - rods and cones. Though structurally and metabolically similar, their function is quite different, though they are equally important to vision. Rod cells are highly sensitive to light allowing them to respond in dim light and dark conditions. These are the cells which allow humans and other animals to see by moonlight, or with very little available light (as in a dark room). However, they do not distinguish between colours, and have low visual acuity (a measure of detail). This is why the darker conditions become, the less colour objects seem to have. Cone cells, conversely, need high light intensities to respond and have high visual acuity. Different cone cells respond to different colours (wavelengths) of light, which allows an organism to see colour.

Both me and my brother can't see at night. It maybe age related.
What I read is that brown eyes have more rod cells than blue eyes.
Of course it was old information and things change.

He said yes, they routinely pulled behind Corvettes and followed them while they ran their plates, mostly checking to see if it was stolen......so they are actually being our friends per that cop.....
