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.

A near-sighted person might correct his vision by wearing diverging lenses with focal length f = -55 cm . When wearing his glasses, he looks not at actual objects but at the virtual images of those objects formed by his glasses. Suppose he looks at a 13 cm -long pencil held vertically 1.7 m from his glasses. Use ray tracing to determine the location of the image. Express your answer using two significant figures in m Use ray tracing to...

A near-sighted person has a far point of 80 cm. A) What kind of corrective lens the person will need if the lens is to be placed 1.5 cm from the eye? The answer is not 78.5, 80 or -1.27 B) What would be the power of the contact lens needed? Assume distance to contact lens from the eye to be zero.

An older person wears bifocals. The lower portion of the lens is
converging and has a focal length of 80 cm. The upper portion is
diverging and has focal length of - 50 cm. What are near and far
points of person’s unaided eye?

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.
