Retinoscopes

Retinoscopes are important tools used in eye examinations by healthcare professionals. A Welch Allyn retinoscope is a diagnostic tool used to measure a patient's refractive error. It projects a beam of light into the patient's eye, and the examiner observes the reflection and movement of the light to determine the prescription needed for vision correction. It helps determine whether a person is nearsighted, farsighted, or has astigmatism.

A Welch Allyn retinoscope is used by ophthalmologists and optometrists to examine and measure the refraction of the eye. This helps in diagnosing vision problems and determining the appropriate corrective lenses. Similar to otoscopes, Welch Allyn offers different models of retinoscopes with varying features and functionalities.
