Description

If you're reading this, you're probably familiar with the vision chart that hangs in every optometrist's examining room--the one with a big "E" at the top. It's officially known as a Snellen chart and has been the basis for measuring what's known as visual acuity since the late 1800s. Think of visual acuity as a quantitative measure of your vision, establishing where your vision is placed on a numeric scale. There are also qualitative measures of your vision, such as your ability to perceive subtle contrast changes, especially in low-light situations. Taken together, these quantitative and qualitative measures determine the overall performance of your vision.
