Refractive error is a common eye problem that affects not only adults but also children. Obviously, we need light in order to see. In this case, the shape of your eyes does not bend light correctly resulting in a blurred image.
It can be treated through the help of an optometrist. Planning for an appointment with your optometrist is the right track because getting an eye exam is an important part of staying visually healthy. It can be corrected through eyeglass, contact lenses, and if recommended, a surgery.
