After the evolution from epithelial cells to eye spots, which can detect light, the development went further on to compound eyes or single-chambered eyes. But the real improvement in creating a good picture was the evolution of the lens. Lenses have the main property of refraction of the light. They are found on top of the compound eyes as chitin lenses or crystalline cones in every single ommatidium with many different refractory properties as well as in single-chambered eyes either as a gelatinous mass or as an epithelial lens-shaped part inside the eye ball. Sometimes a lens is not enough to gather information and an additional mirror helps to survive. Some of the wonderful curiosities that happened in nature are described.
