Suppose the lens-to-retina distance of the human eye is 2.00 cm.

A) What is the power of the eyes, in diopters, when viewing an object 35 cm away? (the answer is NOT 47 or 50)

B) Calculate the power P, in diopters, of the eye when viewing an object 5.5 m away?

A) Power in diopters,P = 1/f = 1/i +1/o = 1/0.35 + 1/0.02

= 52.86

B) Again P = 1/5.5 + 1/0.02 = 50.18
