What Should I Expect From My Total Vision Eye Exam?
Your eye exam should last less than an hour in total and will be entirely painless. If you are joining us at Total Vision for an eye exam for the first time in a long time, or just want a reminder of what to expect, read on for fast facts and more information.
During Your Eye Exam Your Eye Doctor Will:
- Talk to you about your medical history. Certain conditions such as diabetes or high blood pressure can be risk factors for eye diseases. It’s important that your eye doctor gets a full picture of your overall health to give you the best possible care.
- Discuss any vision problems you are experiencing.
- Inquire as to whether you have any family history of vision problems or eye disease.
- Get a sense of your lifestyle - your job, your hobbies - all to best treat your unique needs.
Your Total Vision optometrist will perform a series of tests to evaluate your eye health, determine your glasses and/or contact lens prescription, if necessary. A comprehensive eye exam usually includes:
Retinoscopy & Refraction Tests
Retinoscopy allows your eye doctor to get an approximate sense of what your glasses prescription should be, or if you need one at all. You will look through a device called a phoropter as your eye doctor switches through lenses of differing strengths. As they shine a light in your eyes, they observe how your eyes respond to different lens strengths.
Next, your optometrist performs a refraction test. As you continue to look through the phoropter, your eye doctor will ask you to look at an eye chart across the room. As they cycle through lenses of different strengths, your eye doctor will ask which lenses are delivering clearer vision for you. This allows the optometrist to determine your precise glasses prescription or rule out the need for corrective lenses.
Visual Acuity Tests
When you picture yourself at the eye doctor, you probably envision a chart with letters and numbers, right? What you’re picturing is a visual acuity test. Your eye doctor will ask you to identify letters and numbers of different sizes with one eye covered and then the other. The optometrist determines how closely each eye’s performance measures up to the 20/20 vision standard without any correction like glasses or contacts. This is just one factor to ensure you get the best results.
Also called the “puff of air” test, this test measures your intraocular pressure, the pressure inside your eye. Higher pressure can mean you are at risk of developing or have developed glaucoma, a disease that can threaten your sight.
Visual Field Tests
Your Total Vision eye doctor may use a variety of tests to evaluate your peripheral vision, but overall these tests help your doctor evaluate how well your eyes work together, whether there are gaps in your peripheral vision, and diagnose certain eye conditions or potential eye diseases.
