Retinoscopy - EyeWiki
网页Retinoscopy is an exam technique that objectively measures the refractive error of the eye. This is done by looking through an optical instrument called a retinoscope to observe the movement of reflected light in a patient’s pupil. [2] .
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Retinoscopy (also called skiascopy) is a technique to figure out the refractive error of the eye (farsighted, nearsighted, astigmatism) and the need for glasses without having to ask “which is better, one or two.” The test can be quick, easy, reliably accurate and needs little cooperation from the patient. How is it performed?
