The most common reason that people visit eye doctors is for eye exams. These comprehensive tests do more than determine if you need glasses or contacts. In fact, an optometrist could detect serious conditions through regular screenings. In Georgetown, San Gabriel Eye Center offers eye exams that can help you improve your vision and spot eye conditions.
What to Expect During a Vision Exam
During a vision exam, the optometrist will screen your visual acuity, test your eye function, and look at your eye health.
Visual Acuity Test
The visual acuity test requires you to read letters off both a wall chart and a reading card. The results of the wall-mounted eye chart test determine how sharp your vision is compared to normal vision. For instance, if you have a vision of 20/40, what those with normal vision can comfortably see at 40 feet, you need to move to 20 feet to see. Depending on the results of this test, you may need refraction tests to help the optometrist to find the corrective lenses prescription for your needs.
Eye Function Tests
Eye function tests measure how well your eyes move, react to light, see colors, and see from the side. Normally, an optometrist will use a visual field test to examine your peripheral vision. Ocular motility is a test in which the eye doctor examines how well your eyes move and their alignment.
Eye Health Tests
Eye health tests look for a variety of conditions that can impact vision. These tests include a slit-lamp exam, a tonometry test for eye pressure, and a dilated pupillary exam to look inside the eye. By conducting these eye health tests, the optometrist can see if you have signs of developing problems that could impact your vision now or in the future.
Issues that an Optometrist Screens for During a Comprehensive Eye and Vision Exam
The eye health portion of your eye exam lets the eye doctor monitor your eyes for changes in the pressure, blood vessels, and structures. For example, during the exam in which the optometrist looks at the front of your eyes, they may look for signs of clouding that indicate building cataracts. During a dilated pupillary exam, the eye doctor looks at the blood vessels that supply the retina at the back of the eye. Damage to these blood vessels could indicate diabetic retinopathy, high blood pressure, or macular degeneration. Eye pressure tests determine if you may have glaucoma.
The Importance of Regular Eye Exams
Regular eye exams can spot eye health issues before you notice changes to your visual acuity. Getting a diagnosis during these early phases may increase your chances of recovery or slowing down the progression of the condition. If you put off eye exams, you may not know that you have conditions such as cataracts or glaucoma until your vision has been severely affected.
