An alien race has evolved such that their eyes work exactly like ours except their eyes can be modeled with a biconcave lens. WHen they come to visit us, they'll need some corrective lenses. Why? Based on your understanding of the human eye and multiple lens systems, what kind of glasses would you prescribe? Explain. They can see perfectly fine on their own planet what might this say about their environment?
