Your doctor will be able to see how light bends as it passes through your eye with an automated refraction test. You look into a device that beams light into your eyes and gauges how much of it reflects back. One method we use to assess your eyesight is an automated refraction eye test, which also assists your optometrist in determining the prescription (lens strength) you require for clear vision. Your optician will determine how much vision correction you require in your glasses or contact lenses by using a device known as an autorefractor.The process by which light enters your eyes and is bent, or refracted, is known as refraction. How they accomplish this controls the amount of light focused into the retina at the rear of the eye, which in turn controls how well you see. Optical professionals employ an autorefractor, a device that measures light as it enters the eye and provides a precise estimate of your prescription. It's a terrific place to start when your optician completes the other tests and finalizes your prescription during your visit. Sometimes, especially when testing kids, an optician may do refraction by remotely flashing a light into your eyes in addition to or instead of doing an autorefractor test.
