Eye Exam Doctor in Grand Prairie
Eye exams are important at any age. Most people overlook their vision health until they have an eye problem. Regular eye exams help you prevent and catch eye problems early and get solutions for them. On this page we will talk about eye exams, what happens, and who performs them.
An eye exam is a comprehensive look at all angles of your vision and not just your eyesight. A full eye exam also includes detecting future problems and creating a plan to evade them.
What does an eye exam involve?
During an eye exam, your eye doctor performs the following tests:
Visual acuity: Your eye doctor uses an eye chart to see how well you can see objects at various distances. This test can tell you if you have 20/20 vision.
Lens prescription: Your eye doctor uses a phoropter device that has different lenses to determine which lenses help you see better. This test is used to figure out your eyeglass or contact lenses prescription.
Pupils: In this test, a bright light is shined on your eye to test your pupil.
Peripheral (side) vision: This test is performed to detect if there are other eye problems that you haven’t noticed.
Eye movement: This is a test to check if your eye muscles are working well and your eyes are aligned.
Eye pressure: This test checks for glaucoma. Glaucoma represents a group of eye diseases that cause vision loss.
Front of your eye: This test is performed using a special microscope that checks the eyelids, cornea, iris, and lens for any scars or scratches.
Retina and optic nerve: This test involves the use of dilating eye drops or a retinal scanner that widens your pupil to allow your eye doctor to examine the retina and optic nerve for damage.
Who performs an eye exam?
An eye exam doctor such as an optometrist or an ophthalmologist performs an eye exam. They perform all the necessary tests. An optometrist is responsible for prescribing your glasses or lenses while an ophthalmologist is responsible for prescribing eye medication and performing eye surgery where necessary.
