A doctor may suggest eye exams every two years for people younger than 40 and without any major eye problems. For those above 40, an eye test in Grande Prairie is recommended every 1-2 years, depending on the condition of the eyes.
This blog looks at three eye tests that a Doctor could perform to determine the healthiness of your eyes.
1 - Cover test:
This test reveals how well your eyes work in tandem. The eye doctor will make you stare at a small target at a distance. They will then cover and uncover each eye to see how your eyes move.
Another thing the doctor will observe is whether an eye moves away from the target, which would indicate strabismus. The test may be performed again with a target closer to you.
2 - External exam and pupil responses
The doctor will observe your pupil's reaction to light and how it adjusts to closer objects. They will also check the whites of the eyes and eyelid position.
3 - Refraction testing
A refraction test determines the exact prescription lens you might need, and the doctor will use a computerized refractor. The phoropter will be flipped back and forth between lenses to adjust the prescription while asking you which is better. This test is not needed for those who do not need corrective lenses.
