The enormous variety of eye constructions in the animal world shows that animals use different amounts and different parts of the visible information that surrounds us. Human and non-human eyes consist of pure optics and electronics, but in a biological package, and have been adapted and optimized in various animals for millions of years. Researchers believe that the eyes have evolved at least seven different ways, which is why for example the insect eyes are so different compared to other animals' eyes.
