What is a refraction in an eye exam?

ANSWER

A refraction test is what the doctor uses to get your eyeglasses prescription. You look at a chart, usually 20 feet away, or in a mirror that makes things look like they’re 20 feet away. You’ll look through a tool called a phoropter. It lets the doctor move lenses of different strengths in front of your eyes. The test also helps your doctor spot presbyopia, hyperopia, myopia, and astigmatism.
