The near point of a patients eye is 50.0 cm. (a) What focal length must a corrective lens have to enable the eye to see clearly an object 20.5 cm away? Neglect the eye-lens distance. cm (b) What is the power of this lens? diopters (c) Repeat part (b), taking into account the fact that, for typical eyeglasses, the corrective lens is 2.00 cm in front of the eye. Suppose a lens is placed in a device that determines its power as 3.02 diopters. (a) Find the focal length of the lens. f = cm (b) Find the minimum distance at which a patient will be able to focus on an object if the patient's near point is 30.9 cm. Neglect the eye-lens distance. dmin = cm
