Adults between the ages of 20 to 64 years old should have their eyes checked every 1 to 2 years. Those 65 or older as well as those with particular conditions such as diabetes, glaucoma, cataracts should have their eyes monitored at the very least on a yearly basis.
What should I expect during my eye examination?
An adult eye examination at Dr. Mei-Ling Chanʼs Barrie optometric office takes approximately 30 to 45 minutes. You complete a medical questionnaire; Dr. Chan discusses your health, any visual concerns, your visual needs and wants; she gives you a summary of her findings; and she makes her recommendations.
Here are the nuts and bolts of it:
Case history – yours as well as your familyʼs eye and medical history. Dr. Chan also looks at YOU, not just your eyes. Are there certain conditions, for example acne rosacea which often causes dry eyes, that she needs to be concern with?
Visual acuity – measures the sharpness of your vision
Colour vision test – to rule out colour blindness. It can detect hereditary colour vision deficiencies but also alerts Dr. Chan to possible eye health problems
Binocular vision tests – test how well your two eyes work together
Refraction – measures the precise prescription of your glasses
Slit-lamp examination – using a biomicroscope that provides a highly magnified view of the different structures of the eyes, Dr. Chan can detect signs of eye infection or eye diseases
Dilation – drops to enlarge the pupils. With the help of a high-powered lens, Dr. Chan can view the inside of the eyes to rule out any pathology
Tonometry – measures the pressure inside the eyeball. This is a common test for glaucoma, which unfortunately gives no symptoms until youʼve already suffered a significant vision loss
And then what… – based on your visual needs (occupational and recreational), Dr. Chan will make the optimal recommendations whether it be glasses, contact lenses or vision therapy. Conditions requiring a specialistʼs attention are referred promptly. Dr. Chan makes a point of communicating with your physician all ocular findings pertinent to your overall healthcare. Diabetic patientsʼ yearly eye exams include a letter to the patientsʼ doctors detailing all ocular findings, as are those seen following a referral by their physicians.
