Consider the human eye to be composed of a thin lens of uniform index of refraction n = 1.42, with fluid of n = 1 inside, with the light-receptive cells a distance 25.5 mm from the lens. The eye can "focus" on different distances by changing the radius of curvature of its lens.
1) Find the radius of curvature for this lens when you are looking at very distant objects.
2) Find the radius of curvature for this lens when you are looking at an object a distance of 82 mm from your eye's lens.
