Understanding the Autorefractor

What is an Autorefractor?

An autorefractor is an ophthalmic device used to measure the refractive error of the eyes automatically. The autorefractor shines light into the eye and measures how it changes as it bounces back off the retina. This process provides an objective measurement of refractive error, which can then be used to prescribe corrective lenses.

They are essential in determining the degree of nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. These devices offer quick and reliable measurements, making them invaluable in both clinical and retail optometry settings.
