As a human being that needs glasses to see the accepted norm of 20/20, I’ve always been interested in how our visual perspective of the world varies so greatly. Even among humans there are color discrepancies and a difference in our ability to focus.
Animals extend this question further by being able to see things that are not even perceivable to the human eye. After a new study, scientist have found that cats, dogs and many other mammals may see in ultraviolet light.
