Retinoscope

A retinoscope is a medical instrument used by eye care professionals to measure how well your eyes focus light. During an eye exam, the practitioner shines a light into your eye and observes how the light reflects off the retina. This helps determine your refractive error—whether you are nearsighted, farsighted, or have astigmatism. The retinoscope provides an objective way to assess your vision correction needs, guiding the proper prescription for glasses or contact lenses. It is a quick, painless, and effective tool essential for accurate eye examinations.
