Contact lenses are placed on the eyeball, so the distance from the eye to an object (or an image) is the same as the distance from the lens to the object (or the image). If a person can see distant objects well, but has a nearpoint of 53.0 cm instead of the usual 25.0 cm, what power of contact lenses are needed (in diopters)? The same person now wants to wear glasses instead; they are 1.90 cm in front of...

Suppose that a person's lenses have a refractive power of 2.75 diopters that allow the person to focus on an object that is 25 cm from the eye. The glasses are 2.00 cm in front of the eyes. a) Is the close point of this person greater than or less than 57.0 cm? What is the distance from the near point when the glasses have a refractive power of 2.53 diopters? Explain b) find the close point of this person.
