Final answer:
The far point of a myopic person with a -4.00 D lens prescription is determined using the formula P = 1/f, which yields a distance of 25.0 cm.
Step-by-step explanation:
The question asks about the far point of a myopic person with a contact lens prescription of -4.00 D. The far point is the maximum distance at which a myopic person can see objects clearly without correction. We can find it by using the formula P = 1/f, where P is the power of the lens in diopters (D) and f is the focal length in meters. First, we need to convert the power of the lens from diopters to meters which will give us the focal length (far point). Thus, f = 1/P = 1/(-4.00), which equals -0.25 meters or -25 cm. However, since distance cannot be negative, we take the positive value, which is 25.0 cm.
The correct answer for the myopic person's far point with a prescription of -4.00 D is 25.0 cm.
