There are so many colors that we can see. One thing dogs have in common is that they are color blind. They can only see two colors. So why is this? First, dogs have only two cone cells which limits them to red and green, the same as a color blind person would see. Second, the different structures of the eyes make a difference too. But why can some dogs see better than others. It depends on the cone cells and eye structure also their pupils. Do you know when you’re on your device it acts like sunlight so it keeps us up but when dogs see light they often try to find shade. This is because examination of the pupils shows that there’s is smaller which explains this. The reason why you find your dog lurking at night is because it has incredible night vision which shows why they don’t like the sun. According to UCSB Scienceline, “it has been thought for a long time that dogs are colorblind or can only see black and white, but recent research suggests that a dog's world is not all black and white.This shows that Dog were mainly looked at as colorblind and not the same as us. The structure of an eye means everything is an important thing . If dogs had no structure they probably wouldn’t have an eye. Dogs have very different eyes which explains why other dogs can see better.
