Eli5: Day time vs night time vision

585 views

I learned that felines have (around) 6 times better night vision than us humans. It’s hard for me to get a reference as to how good that is. I thought a good starting place is: How many times better can humans see in the daytime vs the nighttime?

No that is a myth. Their vision is roughly comparable to ours in darkness and *much* worse than ours in daylight. People underestimate just how well we can see compared to most other animals.
