Peripheral Vision Test

As part of a comprehensive eye exam or vision screening, eye doctors almost always include a peripheral vision test.
 
Your peripheral vision is the visual field at the “outside” of your vision. That means, while your eyes may be “focused” on an object directly in front of you, you should still have the ability to see and recognize objects to your left, right, up and down—not directly in your line of sight.
 
Since peripheral vision loss can be a sign of a number of eye diseases, including glaucoma and other optic nerve disorders, side vision must be tested regularly.

How does a peripheral vision test work?

A peripheral vision test takes little time and is usually incorporated into the early portion of the eye exam.
 
The most common type of peripheral vision testing is “confrontational” peripheral vision testing, where your eye doctor asks you to focus on a target directly in front of you (the doctor’s eye, or an upraised finger, for example). With one eye covered, and your focus trained on the target, you’ll be asked to describe things you see in the “side” of your vision.
 
What’s important to remember is to keep focus on the main target and honestly describe what you see. You’ll then cover the other eye and repeat the procedure.
 
Peripheral vision loss indicates there may be an eye problem present, one that can then be tested for in greater detail during your eye examination.
 
There are additional types of peripheral vision testing using automated machines with a series of blinking lights in the outer visual field, or special cards with specific lines and patterns that create forced optical illusions.
 
No matter what the form of test, know that peripheral vision loss is a serious symptom that needs to be evaluated by a qualified eyecare professional.

Thank you for trusting your eyecare with us over the years.  The Foresight Eyecare team follows the government mandate to reduce the spread of the COVID-19 pandemic.  After December 2020 announcements made by the Alberta Government, our clinic is following the revised Infection Prevention and Control policy by the Alberta College of Optometrists.

Patients interested in obtaining eye exam services or eye care products can be seen by appointment only.  Please call ahead, and staff will arrange an appointment time and ask COVID-19 screening questions.  If you have any symptoms of cough, fever, runny nose or shortness of breath, we ask that you call or e-mail us and do not attend the clinic for your scheduled visit.   Within the clinic, please wear a mask and use the hand sanitizer at reception.  Our clinic complies with the City of Calgary bylaw requiring mask covering over the age of two years old.  For patients who are unable to wear a face covering due to medical reasons, the patient can be scheduled for an appointment at a time when minimal number of other patients are in the clinic such as at the beginning or end of the day to ensure appropriate physical distancing requirements.

We are using disposable disinfectant wipes on all surfaces and devices such as front desk counters, chairs, handles in exam rooms and waiting room.  All eyewear that have been touched by patients are continually being sanitized.   Any toys and magazines are stored at this time.  Examination areas are being sanitized with hospital grade disinfectant.  Debit and credit cards but NO CASH payments will be accepted.

COVID-19 symptoms are not always obvious.  We want to fend off this pandemic and minimize risk to our patients and the Foresight staff as front line health workers.   Contact that is closer than 2 m (6 feet) is to be avoided, with barriers in place when this cannot be avoided. We choose to continue to do our work and cautiously take care of our patients with compassion, humility, gentleness, and patience.   It is a challenging and new experience for many of us, so let‘s support each other and prevent virus spread!  Beyond 2020, our focus is on take care of you and keeping Clean Hands, Clear Heads and Open Hearts.   For more information, please refer to the following web pages or phone Health Link 811.
