Fig. 8. Locating the far point of a plano eye in ophthalmoscopic retinoscopy when the retinoscope is 5 cm from the subject's eye. Move the sleeve toward the middle position corresponding to the approximate or calibrated position so that the retinoscopic rays emerge in a parallel bundle and create a bright, thin, focused image on the retina. This position can be used to confirm emmetropia after refractive correction or to confirm the absence of a significant refractive error in an uncooperative subject. The far point found corresponds to infinity. In practice, this step is combined with the steps for estimating any refractive error between -2.25 and + 4.00 D.
