During the comprehensive eye exam, we fully assess your vision. If we determine you need vision correction, we will use the autorefractor to determine the correct lens prescription for your eyes.

How Does the Autorefractor Work?

Autorefractors only take a few moments to determine each measurement for each eye. What’s more, autorefractors are quite reliable and are sometimes used in conjunction with a machine called a phoropter to manually switch lenses in front of your eyes to provide ideal vision correction.

While seated in front of the autorefractor, you’ll be asked to focus on an image or point of light. The autorefractor automatically determines the correction needed to place your “focus point” on top of the retina, the light-sensitive area at the back of the eye responsible for correctly processing images.

The measurement taken by an autorefractor can be translated into a prescription for eyeglasses.

What are the Benefits of the Autorefractor? 

The autorefractor provides highly accurate measurements to determine vision correction needs automatically. Some children and people with special needs may have trouble sitting calmly during a longer eye exam or may have a difficult time describing their visual needs or problems. The autorefractor can capture this information very quickly, and with a high degree of accuracy.
