Glasses can correct some types of refractive error -- the problem that the eye has precisely focusing the incoming light rays on the retina. The main types of refractive error are called: myopia (near-sightedness), hyperopia (far-sightedness), and astigmati. So refraction is important to them because the glasses help to repair their eyes when the eye can't focus on the light entering the eye, hope this helped!!!
