In addition to testing your eyesight, eye exams also assess neurological function, the overall health of your eye, and the external and internal eye structures. Envision’s comprehensive eye exams include a series of tests to check your vision health as well as your prescription. They test for refractive errors, color vision, and more.
Envision’s doctors can uncover eye conditions and other health issues that you might not be aware you have by performing these simple tests. Moreover, your vision changes as you age – the eyeball changes shape and the lens can lose its flexibility. You might not even realize your eyesight is getting worse. Bearing all this in mind, routine eye exams provide an opportunity to have your eyesight reassessed and confirm that you are receiving the eye care you need.
Visual Acuity Test: You’ll read aloud from an eye chart with letters that get smaller and smaller to determine the clarity of your vision.
Retinoscopy: The doctor will shine a light into your eye to gauge your prescription based on the reflection of the light.
Refraction: The estimated prescription is further refinaed in this test. The doctor will flip lenses on an instrument called a phoropter and ask you through which lens you see clearer.
Cover Test: The doctor will cover each of your eyes with a paddle while you focus on an object far away to check that your eyes are working together.
Tonometry: This test measures the pressure of your eyeball, an early indicator of glaucoma and other eye diseases. The doctor may choose to obtain this information by performing a puff test or by numbing the eye and using a tool to swiftly tap the eyeball.
Color Testing: You’ll look at a multi-colored dotted image with a number embedded in the dots to check if you have a color vision deficiency.
Slit Lamp Exam: The doctor will use a biomicroscope to magnify the front of your eye and observe the eye structure.
Dilated Fundus Exam: The doctor administers eye drops to dilate your pupils and inspect the inside of your eye. In addition to assessing your vision and general eye health, dilating your pupils can help our doctors determine whether you might have diabetes, high blood pressure, an eye tumor, or certain infectious diseases.
