    Where did you get those numbers? The focal length of the eye is about 17mm - are you sure that isn't the change in focal length from near-far.

    These numbers are just from my homework problem, and yes it is focal length (I wrote down the problem exactly).

    I tried subtracting image distance from focal length and object distance from focal length but neither works.

    Can someone please help? It's due today at 12:40.
