Retinoscopy - Wikipedia
网页Retinoscopy is a technique to obtain an objective measurement of the refractive error of a patient's eyes. [1] The examiner uses a retinoscope to shine light into the patient's eye and observes the reflection (reflex) off the patient's retina .

网页2022年4月28日 · Retinoscopy (or skiascopy) is a technique that uses light and lenses to determine “where” the far point lands and quantifying that measure. Based on the eye’s light reflex we can get a baseline reading and understanding of the patient’s refractive error. Relevant qualitative input can be seen with the retinoscope as well.
