A person has far and near points of 84 cm and 15 cm, respectively. What is the percent change in the power of the person’s eyes when going from relaxed to accommodated vision? Take the lens-to-retina distance to be 2.0 cm.
A person’s prescription for bifocals is –0.139 diopter for distant vision and +3.78 diopters for near vision, the near vision being accomplished by inserts into the distant vision lens. What is the net power of the near vision correction?
Calculate the power of the eye when viewing objects at the greatest and smallest distances possible with normal vision, assuming a lens-to-retina distance of 2.00 cm (a typical value).

- A hunter who is a bit of a braggart claims that from adistance of 1.6 km he can selectively shoot either of twosquirrels who are sitting ten centimeters apart on the same branch of atree. What’s more, he claims that he can do this without the aid of a telescopic sight on his rifl e. (a) Determine the diameter of the pupils of hiseyes that would be required for him to be able to resolve the squirrels asseparate objects. In this calculation use a wavelength of 498 nm (in vacuum) for the light. (b) State whether his claim is reasonable, and providea reason for your answer. In evaluating his claim, consider that the humaneye automatically adjusts the diameter of its pupil over a typical range of2 to 8 mm, the larger values coming into play as the lighting becomesdarker.
