Do dolphins have good eyesight?
Dolphins have 20/20 vision both above and below the water. They are able to see in both environments, because they can control the way light enters their eye via specialized, ocular muscles. When viewing an object underwater, light does not bend as it enters their eye, and when viewing an object above water, the light is bent as it enters their eye. Since their eyes are on the sides of their head, dolphins (and most small toothed whales) have both monoscopic and stereoscopic vision. Seeing monoscopically means a dolphin is able to independently process two different images at the same time. Dolphins are also able to see stereoscopically, focusing both eyes downward toward their stomach (most in focus about 3-5 feet away). Dolphins see 173 degrees to each side from the tip of their rostrum to the tip of their tail. They have three known blind spots – directly above them, directly behind them, and directly in front of their rostrum. It is still unclear as to whether dolphins can see in c
