Can you please show me how these problems would be solved:

A farsighted eye is corrected by placing a converging lens in front of the eye. The lens will create a virtual image that is located at the near point (the closest an object can be and still be in focus) of the viewer when the object is held at a comfortable distance, usually taken to be 25.0 cm. If a person has a near point of 35.5 cm, what power reading glasses should be prescribed to treat this hyperopia? Assume that the distance from the eye to the lens is negligible. power: I l diopters Enter numeric value A physicist's left eye is myopic (i.e., nearsighted). This eye can see clearly only out to a distance of 27 cm. Find the focal length and the power of a lens that will correct this myopia when worn 2.0 cm in front of the eye. Is this a converging or a diverging lens? 0 converging O diverging
