What is the power P of the eye when viewing an object 61.0 cm away? Assume the lens-to-retina distance is 2.00 cm , and express the answer in diopters.

The power of the eye is 51.64 diopters

Explanation:

The power of the eye is given by;

where;

P is the power of the eye in diopter

f is the focal length of the eye

is the distance between the eye and the object

is the distance between the eye and the image

Given;

= 61.0 cm = 0.61 m

= 2.0 cm = 0.02 m

Therefore, the power of the eye is 51.64 diopters.
