visual acuity testing
Visual acuity testing measures how well you can see sharpness and clarity. Typically conducted during an eye exam, it involves reading letters or symbols on a chart at a distance. The results are usually expressed as a fraction, like 20/20, where the first number indicates the distance from the chart and the second shows the distance at which a person with normal vision can read the same line. This test helps identify vision problems, ensuring you receive appropriate care or corrective lenses if needed. It’s a crucial part of maintaining good eye health.

Visual acuity testing measures how well you can see at different distances. It typically involves reading letters from a chart, known as the Snellen chart, placed at a standard distance (usually 20 feet). Each line of letters decreases in size, and your ability to read them indicates the sharpness of your vision. Results are expressed as a fraction, such as 20/20, meaning you can see at 20 feet what a person with normal vision sees at that distance. This test helps healthcare providers determine if you need corrective lenses or other interventions for your eyesight.
