Dogs’ Eyes Have Changed Since Humans Befriended Them
This is a good opportunity to educate the general [HN] community about dogs:1. They can only see blue/yellow. Not like humans' RGB.2. They are short sighted. For far away objects, their sight is like a T-Rex, they can see moving objects, not stationary objects. Remain still, and they can't see you. Then again, they can smell you, especially if it's downwind.3. Their flicker fusion threshold is higher than humans. If you show them a cute mobile picture of a baby, they'll see a lot of flickering. As well, did you know lights have a flicker? If you think it's bad, it's even worse for dogs which can lead to stress.More:https://dog-vision.com/https://www.dogwalkersmelbourne.com.au/articles-dog-walking-...
