Autorefractor

If you’ve discovered you might need vision correction during your eye examination, it’s vital to determine just how “much” your eyes need to be corrected with lenses or contact lenses. This is called measuring your “refraction.

Autorefractors automatically measure this value during an eye examination.

While seated with your chin in a stabilizing chinrest, 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.

In eye exams for small children, or for people with special needs who may have trouble sitting calmly during an extended exam, or verbally describing their vision problems—autorefractors give highly accurate measurements used to determine vision correction needs, automatically.

How do autorefractors 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 phoroptor to manually switch lenses in front of your eyes to provide ideal vision correction.

Dear Patients,

Ontario will be entering LOCKDOWN on December 26 @12:01AM by order of the Government of Ontario for at least 28 days. Please note that medical care including Optometry services are NOT impacted by these changes.

We will continue to operate following Public Health protocols including screening, PPE, handwashing & sanitizing as well as maintaining physical distancing where possible.

We are open throughout the holiday season (Closed Dec25-27 and Dec31-Jan3) for orders, with very limited in person care. We will be open for full care on Jan 4. We will reserve two urgent care appointments each day during the province-wide lockdown to help reduce the number of eye related emergency room visits for our current patients.

If you are experiencing an eye emergency (loss of vision, double vision, distortion to vision, ocular pain, photosensitivity or other visual symptoms) please contact the office at 519 822 2710 for advice before presenting to the emergency room.
