发明名称 DEVICE AND METHOD FOR CALIBRATING RETINOSCOPES
摘要 A device for calibrating retinoscopes for diverging and/or converging streak and spot retinoscopy and a method for calibrating retinoscopes to produce a given convergence or divergence of light emitted from the retinoscope from a fixed retinoscopic working distance to produce a predetermined pupillary reflex endpoint at neutralization of a refractive error, thereby resulting in a more accurate corrective eye prescriptions and evaluation of the visual system.
