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

The human eye and animal eye are very different from each other. A 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.

Cats eyes are opposite to us, they have a 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.
