is the bending of light rays in order to focus them. The cornea and the lens achieve refraction of light which passes through the eye. Optimal focusing of light in the eye results in a clear image being received by the brain.

In order for an eye to see clearly, the light rays must come to a perfect focus when they reach the fovea. The bending of the light rays is called refraction. Each eye has its own characteristic refractive error. An instrument (retinoscope) is used to determine this error. The examination is called refracting the eye. From the refraction, the examiner learns the strength of lens necessary to provide the clearest vision for each eye.
