Which term best describes retinoscopy as part of the refraction process?

Retinoscopy is classified as an objective method in the refraction process because it relies on the observation of light reflexes in the eye rather than on the patient's verbal feedback or subjective feelings about what they see. During retinoscopy, the examiner uses a retinoscope to shine light into the patient's eye and evaluates the movement of the light as it reflects off the retina. This allows the examiner to determine the refractive error of the eye without needing the patient to indicate which lens power appears clearer.

In contrast, subjective methods involve patient input to assess their vision, typically through techniques like using a phoropter and asking patients to choose between different lens options. The objective nature of retinoscopy provides a more consistent and reliable measurement of refractive errors, making it a valuable tool in the overall refraction process. Other terms provided, such as comparative or assessive, do not accurately capture the fundamental nature of retinoscopy as a technique focused on observable data rather than subjective responses or assessments.
