A patient with a refractive myopia cannot see objects clearly if they are further away than 10 m. To be able to drive safely and obtain his driving license, he needs to be able to clearly see objects up to 100 m away. In this problem, Pmin eye = minimum optical power of the patient’s natural eyes, Pmin combo = minimum optical power of the patient’s natural eyes + corrective glasses, and Pmin glasses = minimum optical power of the corrective glasses Calculate the minimum combined optical power for the patient’s eyes plus their corrective glasses (Pmin combo) that is required for the patient to see an object at 100 m.

A patient cannot clearly see any object that lies closer than 32.0 cm to her right eye. However, the patient wishes to see objects as close as 20.0 cm with that eye. The patient requests eyeglasses to address the problem. (a) Is the patient nearsighted or farsighted? nearsightedfarsighted (b) If the eyeglass lens lies 2.10 cm in front of the patient's eye, what is the minimum distance p (in cm) separating the lens from an object she wants to see? (Give your answer to at least three significant digits.) cm (c) The patient is unable to focus clearly on anything closer than 32.0 cm to her eye (this being the patient's near point). The image formed by the eyeglass lens must therefore be 32.0 cm from the eye. How far, then, (in cm) would the image lie from the lens? (Give your answer to at least three significant digits.) cm (d) The image lies on the same side of the lens as the original object. Is the image real or virtual, and is its position q positive or…
An office administrator realizes that she is having trouble doing her work due to eyesight problems. Her optometrist determines that without glasses she can focus clearly only on objects that lie at distances between 0.450 m and 4.00 m. The optometrist decides that the best way to handle her eyesight problems is to prescribe bifocals that will give her normal visual acuity from 25.0 cm out to infinity. After trying on several pairs of glasses frames, they agree that the glasses will be a distance of 2.20 cm from her eyes. (a) Determine the refractive power needed for the bifocal part that will correct for her nearsightedness (include the sign). D What type of lens is needed? O converging O diverging (b) Determine the refractive power needed for the bifocal part that will correct for her farsightedness (include the sign). D What type of lens is needed? O converging diverging
To fit a contact lens to a patient's eye, a keratometer can be used to measure the curvature of the cornea-the front surface of the eye. This instrument places an illuminated object of known size at a known distance p from the cornea, which then reflects some light from the object, forming an image of it. The magnification M of the image is measured by using a small viewing telescope that allows a comparison of the image formed by the cornea with a second calibrated image projected into the field of view by a prism arrangement. Determine the radius of curvature of the cornea whenp = 28.0 cm and M = 0.0140.
