Refraction Testing
Refraction testing is a diagnostic procedure used to measure the refractive error of the eye, including nearsightedness, farsightedness, and astigmatism. This test helps determine the appropriate prescription for corrective lenses to improve visual acuity and clarity. It involves the use of a phoropter, which allows the eye care professional to determine the ideal lens power needed for optimal vision correction. Refraction testing is typically performed during a comprehensive eye examination to assess the overall health of the eyes and identify any vision problems that may require treatment.
