    Goal Apply geometric optics to correct nearsightedness. Problem A particular nearsighted patient can't see objects clearly when they are beyond 24 cm (the far point of the eye). (a) What focal length should the prescribed contact lens have to correct this problem? (b) Find the power of the lens, in diopters. Neglect the distance between the eye and the corrective lens. Strategy The purpose of the lens in this instance is to take objects at infinity and create an image...

    Without corrective lenses, a person's far point is 17.2cm and the power of their relaxed eye is 51.2 D. A lens is placed 1.85cm away from the eye. What power will the lens be to allow them to see objects at a distance? Can you explain why the relaxed eye has a power of +51.2? When they are nearsighted shouldn't diopters be negative??
