A person is to be fitted with bifocals. She can see clearly when the object is between 30 cm and 1.5 m from the eye. (a) The upper portions of the bifocals (Fig. P25.16) should be designed to enable her to see distant objects clearly. What power should they have? (b) The lower portions of the bifocals should enable her to see objects located 25 cm in front of the eye. What power should they have?
In an alternate universe, you are a brilliant optician. A young Harry Potter comes to
you for a diagnosis. Alas, you find he has hyperopia. You measure his near point to be
1.5m from his eyes. Determine the power of the eyeglasses that will allow him to see
nearby objects up to 25cm from his eye clearly if the eyeglasses will be 0.9cm in front
of his eyes.
The man has a range of vision from 15 cm to 150 cm. What optical power of lenses should he wear at

- Figure P26.72 shows a thin converging lens for which the radii of curvature of its surfaces have magnitudes of 9.00 cm and 11.0 cm. The lens is in front of a concave spherical mirror with the radius of curvature R = 8.00 cm. Assume the focal points F1 and F2 of the lens are 5.00 cm from the center of the lens. (a) Determine the index of refraction of the lens material. The lens and mirror are 20.0 cm apart, and an object is placed 8.00 cm to the left of the lens. Determine (b) the position of the final image and (c) its magnification as seen by the eye in the figure. (d) Is the final image inverted or upright?

This instrument places an illuminated object of known size at a known distance p from the cornea, which then reflects some light from the object, forming an image of it. The magnification M of the image is measured by using a small viewing telescope that allows a comparison of the image formed by the cornea with a second calibrated image projected into the field of view by a prism arrangement.

To be able to drive safely and obtain his driving license, he needs to be able to clearly see objects up to 100 m away.
