Eye refraction is how the power of the eyeglasses or contact lenses is measured. It is based on how the light rays bend to process the visual stimuli. It is expressed in the measurement of distance and clarity. Refraction tests can detect other eye problems as well. A refractive error in the eye leads to difficulty processing images on the retina.
