context: Refractive error is a refraction error in which the structure or location of the cornea and lens of the eye differs so that the image of a distant object on the retina is blurred. Inaccuracies occur when the intersection of light beams does not hit the retina but behind or in front of it. There are three types of refractive defects: remoteness, proximity and astigmatism.
