The maximum possible angular magnification (M) of a converging lens for a person with normal vision is given by the formula M = 1 + (D/f), where D is the least distance of distinct vision (usually taken as 25 cm or 0.25 m for a person with normal vision) and f is the focal length of the lens in meters. Converting the focal length to meters gives f = 0.05 m. Plugging the values into the formula gives M = 1 + (0.25/0.05) = 1 + 5 = 6.
