It estimates the lens power needed to focus light on the retina for clearer vision. It is commonly used in optometry and ophthalmology clinics, especially for children and patients who cannot give reliable responses. It is often paired with subjective refraction, where the patient fine-tunes the prescription by choosing which option looks clearer."}
