is examined by comparing optical designs of the eyes of present day animals and comparing the advantages and disadvantages of each design. One can extrapolate from the eye designs of today that these eyes may have benefited the animals to be able to adapt to their environment. It is interesting to note that of the myriad of species that ha ...

Introduction In order to understand about , we must first have an understanding of its structure and function. On a more basic level, we must also have an understanding of basic optical principles. To gain insight into why ...
