Refraction errors include myopia (nearsightedness), hyperopia (farsightedness), astigmatism (change to the shape of the eye), and presbyopia (farsightedness specifically due to aging). People who have a refraction error in their vision experience problems focusing due to issues with the shape of their cornea in their eye, which then refracts light in a way that the brain cannot interpret the signals well through the optic nerve. For example, someone with a 20/16 vision can see objects at 20 feet as though they were at 16 feet. Still, it is possible to have better eyesight than 20/20 vision.Д«eing able to see objects at a distance greater than 20 feet away means you have a sharper vision or greater distance vision. Having 20/20 means measuring your ability to see clearly at a distance of 20 feet. That includes providing a beyond 20/20 vision on some occasions for some patients. LASIK has helped millions of people get normal vision if they are nearsighted, farsighted, or have astigmatism.
