Optical system the rays pass through, the diffraction curve, and fall / focus on the retina, this process is called refraction / Refraksi. Total strength of all components of refraction was called Dioptri (D). If the total powernya 0 (Zero), the object being viewed by us as the shadows fall right in the retina. This condition is called Normal Eye.
