Quizplus · Accepted Answer

The far point of a myopic person can be calculated using the formula 1/f = P, where f is the focal length in meters and P is the power in diopters. Given the power of the lenses is -3.00 diopters, the focal length (f) is -1/3 meters, or -0.33 meters. The negative sign indicates that the focus is on the same side as the light source, which is typical for myopic correction. However, since the question asks for the far point, we consider the absolute value, which is 0.33 meters.
