Eye Tests: Different Types

At an eye exam, you can expect to have several basic tests. The most common tests are glaucoma testing, visual field testing, and retinal imaging.

The retinoscopy is used in order to measure the curvature of your cornea. As you gaze through the phoropter, the eye doctor flips different lenses in front of your eyes. You focus on a prominent object in front of you (often the “E” on the top row of an eye chart). The optometrist shines a light into

Visual Acuity Test

When you think of your eye exam, this is probably what comes to mind: using one eye at a time, you’ll read letters from a sign that is positioned a specific distance away from you. 

Your optometrist uses your responses to determine how each eye’s vision level compares with standard 20/20 vision.


Refraction Test

The retinoscopy test determines your eyeglass prescription along with a refraction test. During the vision test, you also gaze into the phoropter and look at the eye chart on the opposite wall.

Throughout the eye test, you’ll see a series of lens pairs. The optometrist will ask you which of two lens options lets you see more clearly. Based on your answers, the optometrist will determine whether your eyes are nearsighted, farsighted, or affected by astigmatism.

There are other tests that can be done including but not limited to Intraocular Pressure Measurement, and Keratometry Test. Speak to our Optom in Lakeside Mall Benoni today for quality eye tests that are suited for your sites condition. Contact us here
