If you're under 40 and don't have any serious eye issues, your doctor may advise getting your eyes checked every two years. According to the condition of the eyes, an eye test in Grande Prairie, AB, is suggested for people over 40 every one to two years.
This blog examines three eye exams an optometrist might administer to check the condition of your eyes.
1 - Refraction testing
The doctor will use a computerised refractor to perform a refraction test to determine the precise prescription lens you might require. You will be asked which is preferable as the phoropter is switched back and forth between lenses to alter the prescription.
This eye test in Grande Prairie would not be necessary for those who do not require corrective lenses.
2 - Cover test
This exercise displays how well your eyes operate together. The eye doctor will make you focus on a distant, small object. Then, each eye will be covered and unveiled so they may see how your eyes move.
The doctor will also search for signs of strabismus, which might be indicated by an eye moving away from the target, during an eye test in Grande Prairie.
3 - Visual Field Test
This test aids in determining your field of vision, or what you can see without moving your eyes, and side vision, for the immediate area in front of you.
The doctor employs computer software that causes a bowl-shaped device called an auto-perimeter to flash a few tiny lights as you look into it. You could be instructed to click a button when you notice the lights.
