Retinoscopy is a technique used to measure an individual’s refractive error.It is used to determine the amount of correction required to correct the patient's vision.
It involves shining a streak of light into the eye and then observing the reflection from the back of the eye.The light is moved in and out of the eye to see how the reflection changes.
This helps the doctor determine the power of the corrective lenses that are needed.Retinoscopy is a very precise and accurate method of measuring the refractive error of the eye.
It is typically used to measure the refractive error of young children and those with strong refractive errors.
