Retino-what? What Happens During your Eye Exam

There may be a few tests that you have experienced at an eye exam and questioned what they measure. Having beams of light shined into your eye could be an example. This is one way eye doctors test the refractive error of your eye, and it's called retinoscopy. By just examining the reflection of light off your retina, your optometrist can determine if you are nearsighted, farsighted or have astigmatism, and can also measure the prescription you would need to correct your vision.

The main thing an eye doctor is checking for during this exam is how well your eyes can focus. We do this looking for what's known as the red reflex. The retinoscope aims light into your eye, and a reddish light reflects through your pupil and off your retina. We use the light to measure your focal length, or in other words, to measure the precise angle of refraction of light off your retina. And this is what tells us how well your eye is able to focus. If it becomes clear that you can't focus properly, we hold several prescription lenses in front of the eye to determine which one will correct the refractive error.

Your eye doctor will perform your exam in a dark room. To make your eyes easier to examine, you'll generally be asked to focus on something behind the doctor. The exam doesn't include charts to be read, which means that a retinoscopy exam is also a very good way to accurately determine the prescriptions of the speech-impaired, or young children.

Because of the COVID 19 Virus we will only be staying open to meet the needs of patients with eye problems and emergency exams.

We will be deferring routine exams and delaying contact lens exams until further notice. We will be supporting our patients who were unable to come for their contact lens exams, due to these new restrictions, by extending your current contact lens prescriptions, whenever possible. Please call to discuss this option with us.

When all is settled, we will be calling our postponed patients to get them back in for those exams.

Patients over the age of 60 or in a high risk category will not be seen so please call ahead and speak to us before you come by.

If you have an emergency or medical issue, call us! We’re here to help!

Thank you so much!!! 972-210-2100
