I want to learn about the human eye. I could read a lot of online literature about it.
However, ideally I would like to study human's eye by solving some maths exercises. I suspect people have done this before. How would we have glasses otherwise?
Maybe you know good maths notes + PROBLEMS that would give me an insight into how an eye works?
The notes don't have to comprise a whole course. One chapter is enough, as long as there are some maths exercises attached.
