Retinoscopy (Ret) is a technique to obtain an objective measurement of the refractive error of a patient's eyes. The examiner uses a retinoscope to shine light into the patient's eye and observes the reflection (reflex) off the patient's retina. While moving the streak or spot of light across the pupil the examiner observes the relative movement of the reflex or manually places lenses over the eye (using a trial frame and trial lenses) to "neutralize" the reflex.

    chandan kumar 1 buwan ang nakalipas Jack C Copeland first invented streak retinoscope in 1920. I just want to add few more lines- a semidark room preferably 6 mt or small room of 3 mt can also used for retinoscope with the help of mirror. Working distance lens should always be kept in last compartment of trail frame near to eye .
