A person's prescription for her new bifocal glasses calls for a refractive power of -0.400 diopters in the distance-vision part, and a power of 1.85 diopters in the close-vision part.What are the near and far points of this person's uncorrected vision? Assume the glasses are 2.00 cmfrom the person's eyes, and that the person's near-point distance is 25.0 cm when wearing the glasses.

A physicist can see distant things clearly when wearing -2.00-diopter eyeglasses. Each lens rests 1.55 cm in front of the eye. (a) What focal length (in cm) describes the lenses? (b) Determine the far point (in cm) for this physicist's eyes. (c) is the physicist nearsighted or farsighted? nearsighted farsighted (d) The physicist decides to replace eyeglasses with contact lenses, one of which rests directly on each eye. What would the contact lens power be (in diopters) in order to...

A child's far point is 129 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the child's eyes are identical, with each retina lying 1.80 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point? (Enter your answer in...

Sometimes a person cannot clearly see objects close up or far away. To correct this type of vision, bifocals are often used. The top half of the lens is used to view distant objects and the bottom half of the lens is used to view objects close to the eye. A person can clearly see objects only if they are located between 40 cm and 198 cm away from his eyes. Bifocal lenses are used to correct his vision. What...
