ANIMAL FACTS ,LOOK HOW THEY SEE THE WORLD

In higher living organisms eye is a complex optical system which collects light from the surrounding and focus through the lenses to form a image.

In micro-organisms eye  just detect the surroundings, either dark or light. 96% of animal species around the world have a complex optical system. Many organisms with color vision are also able to detect ultraviolet light which humans cannot see.

Human eye and animal eye are very different from each other. Human eye can take a million impressions and can tell difference between eight million different colors but have you ever wondered how your dog or cat and other animals see you and the world.So today take a look at some animal facts and see the world from their eyes.

THE CAT VISION: Cats eyes are opposite to us, they have high concentration of rod receptors and low concentration of cone receptors. Cats can’t see clear colors and details but they have the ability to see clearly in dark due to the high concentration of rod receptors.

Cats can’t focus on objects more than twenty feet away but on the other hand they have very sharp reflexes and can pick up movements instantly as compared to us. They are red and green colorblind.

THE DOG VISION : Human eyes have three detecting cells called cones while dogs have only two which are blue and yellow, they don’t have red and green detecting cells. Their vision is similar to that of a cat. Dogs are virtually colorblind so they are mostly dependent on their heightened sense of smell.

Dogs can see better in the dark as they have more rods in retina which enables to see better in dark. They can detect small movements way faster than humans.

THE BIRD VISION: Science says that birds can see ultraviolet spectrum which humans cannot see. Birds have four cones and also have a deep fovea which acts like a telephoto lens on a camera. They need excellent vision for flight and they can detect a rabbit twitch its ears from 2 miles away.

They can change the shape of their eye lenses too to get a greater view of the area and have eyes on their sides so they can see widely as well.
