A near sighted person wears corrective glasses made of a diverging lens with a focal length of f = −50 cm. The result is that far away objects appear much closer, and the person sees this image rather than the actual object. Suppose a 12 cm long pencil is held vertically at a distance of 2.0 m from the person. Determine the height and location of the formed image.

    When glasses (or contact lenses) are used to correct nearsightedness, where should the corrective lens form an image of an object located at infinity in order for the eye to form a clear image of that object? The lens should form the image at the near point. The lens should form the image at the far point. The lens should form the image at a point closer to the eye than the near point. The lens should form the image...

    3. For a person who is near-sighted, they have an eyeball that is longer/shorter than normal. This means the rays form an image in front of/behind the retina. To correct their vision, they need a diverging/converging lens in front of their eye. College Physics II Human Eye Lab Page 1 4.
