Others include color vision, peripheral vision, and depth perception. Optometrists, driver’s license bureaus, and many other organizations use this test to check your ability to see.
The Snellen test uses a chart of letters or symbols. It is a common chart found in many eye doctors' offices. Viewed from 14 to 20 feet away, this chart helps determine how well you can see letters and shapes.
