What does 20/20 Vision Mean?

Have you ever wondered what those numbers on your eyeglass prescription actually mean? Although reading an eye chart is a fairly simple test, it provides a very accurate way to measure your visual acuity or the sharpness of your vision. You'll also need a few other tests, in addition to the results of your eye chart reading, before your optometrist hands you your eyeglass prescription.

Reading an Eye Chart Provides an Accurate Representation of Your Vision

Every eye exam includes a reading of the Snellen eye chart. The chart contains 11 lines of random letters, each line smaller than the preceding line. Patients were once required to stand exactly 20 feet away from the chart, but optometrists use mirrors today to approximate that distance.

The chart is read from the top to the bottom. Each line corresponds to a specific measurement, such as 20/20 or 20/80. If your vision is 20/60, you can read words clearly at 20 feet that people with normal vision can read at 60 feet. Although 20/20 is considered normal vision, some people can see even better than 20/20. If you can read the bottom line of the eye chart clearly, your vision is 20/10.

In addition to reading the Snellen eye chart, you may also be asked to read text on the small printed card that you'll hold in your hands. This test evaluates your near vision.

Other Eye Tests Augment Your Eye Chart Measurement

Your optometrist uses a variety of tests to determine your prescription, if needed, and assess the health of your eyes, including:

These guys are the most caring people I have ever met. They will make sure you have the best eye care and eye glasses if you need them. Go with these guys, they except all kinds of insurances including state. And I've found them to be very comfortable despite me being very uncomfortable with eye doctors.
