Question:
Is it correct that auto-refractor measurements are only used as a starting point for the eye chart examination?
Answer:
Correct. While the auto-refractor is a helpful tool, a more precise measurement of a patient’s visual acuity requires use of a phoropter. This is where you sit down, position your head within the chin rest, and look through a binocular-like device. Your eye care professional tests each eye by asking you to pick the clearer of two images seen through the phoropter. This test allows your eye doctor to craft a prescription that delivers your “best-corrected” vision.
