What term refers to the strength of a lens prescription?

Lens Power
Diopter Measurement
Correction Factor
Optical Strength

The correct answer is: Lens Power

The term that refers to the strength of a lens prescription is "Lens Power." This concept is crucial in optics as it quantifies how much the lens can bend light. The lens power is commonly measured in diopters, which indicates the degree of convergence or divergence the lens provides to light rays entering the eye. A higher power indicates a stronger lens, which is necessary for correcting vision problems such as myopia (nearsightedness) or hyperopia (farsightedness). While diopter measurement is relevant to lens power, it is specifically the measurement unit rather than the term for strength itself. Correction factor and optical strength are not standard terms used in reference to lens prescriptions, making lens power the most accurate choice in this context.
