What is a phoropter?

ANSWER

A phoropter is the big lens machine that helps your eye doctor figure out what lens prescription you need. You’ll look through the phoropter and say which lens choice helps you see the best. Sometimes, the doctor looks at your eye through a handheld device called a retinoscope and may also use handheld lenses. Then he’ll offer you different choices in lenses through the phoropter to refine the fix until you can see the vision chart clearly. After he measures both eyes, he’ll give you a prescription for glasses or contacts.
