A retinoscope is used to shine a beam of light into the eye. Movement of the light gives a characteristic reflection in the pupil indicating hyperopia, myopiaor astigmatism. Lenses of varying power are placed in front of the eye until the refractive (focusing) error is cancelled out. In young children it is necessary to dilate the pupil and relax the focusing muscle with eye drops to get an accurate test. The eye drops make the child a little light-sensitive and blur the vision for several hours. The drops take 40 minutes to work fully.
