WebFeb 26, 2024 · Refractive errors are disorders that affect the way your eyes bend light. They cause certain objects to appear blurry. These disorders are very common and are caused by abnormalities in the shape of the eye. You can either be born with refractive errors or develop them later in life. WebNov 5, 2024 · Since the wavelength of light is less than a micron (a thousandth of a millimeter), it acts like a ray in the many common situations in which it encounters objects larger than a micron, such as lenses. For rays passing through matter, the law of refraction is used to trace the paths.
