autorefractor

An autorefractor is a machine used by eye care professionals to measure your prescription for glasses or contact lenses. It works by shining a light into your eye and analyzing how the light changes as it reflects off the back of your eye. This helps determine whether you are nearsighted, farsighted, or have astigmatism. The process is quick, non-invasive, and provides an accurate starting point for creating your eyeglass or contact lens prescription. It’s an essential tool that helps ensure you get the correct visual correction for clear, comfortable vision.
