Which of the following prescriptions shows the presence of antimetropia?

Antimetropia is a condition characterized by one eye being hyperopic (farsighted) and the other being myopic (nearsighted). In the provided prescription, one eye has a positive value, indicating hyperopia, while the other has a negative value, indicating myopia. Specifically, in the case of O.D. (right eye) with a prescription of +1.00, it denotes that the right eye is hyperopic. Conversely, O.S. (left eye) has a prescription of -1.00 which signifies that the left eye is myopic.

This combination of a hyperopic eye and a myopic eye exemplifies antimetropia, as it specifically involves the two different refractive errors in each eye. The other options showcase refractive errors that do not identify this condition; both eyes in those prescriptions either have the same type (myopic or hyperopic) or are both nearsighted or both farsighted. Thus, the presence of both a positive and negative prescription in the correct answer distinctly qualifies it to demonstrate antimetropia.
