Question

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 -3.00 diopters, the focal length (far point) is 1/-3 = -0.33 m. The negative sign indicates that the focus is on the same side as the light source, which is typical for myopic correction, but the distance is 0.33 m.
