-Your eye is a complex system of multiple [[eyeballs|layers of material]] with different [[refraction|refractive indexes]], all trying to project the great big wide world onto your tiny retina.  Sometimes there is a mismatch between the refraction of light into the eye and its length, and the focusing system at the front of the eye misses its target in the back.  This causes [[near-sightedness]] or [[far-sightedness]], which is not a medical disease in and of itself, but just a description of your refractive state not being perfect.
+'''Refractive state''' (also called '''refractive error''') is the lens that causes parallel light rays (distant light) to be focused on the retina when [[accommodation]] is relaxed.
