Dogs’ Eyes Have Changed Since Humans Befriended Them
This is a good opportunity to educate the general [HN] community about dogs:<p>1. They can only see blue/yellow. Not like humans' RGB.<p>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.<p>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.<p>More:<p><a href="https://dog-vision.com/" rel="nofollow">https://dog-vision.com/</a><p><a href="https://www.dogwalkersmelbourne.com.au/articles-dog-walking-pet-sitting/66-dog-canine-vision-seeing-compare-human.html" rel="nofollow">https://www.dogwalkersmelbourne.com.au/articles-dog-walking-...</a>
