This test can be done as part of a routine eye exam. The purpose is to determine whether you have a refractive error (a need for glasses or contact lenses). For people over age 40 who have normal distance vision but difficulty with near vision, a refraction test can determine the right power of reading glasses. See more This test is performed by an ophthalmologist or optometrist. Both of these professionals are often called "eye doctor." You sit in a chair that has a special device (called a phoroptor or refractor) attached to … See more If you wear contact lenses, ask the doctor if you need to remove them and for how long before the test. See more You have a refractive error if you need a combination of lenses to see 20/20 (1.0). Glasses or contact lenses should give you good vision. If you have a refractive error, you have a "prescription." Your prescription is a series of numbers … See more If your uncorrected vision (without glasses or contact lenses) is normal, then the refractive error is zero (plano) and your vision should be 20/20 (or 1.0). A value of 20/20 (1.0) is normal vision.
