Your [[eye]] is a complex system of multiple 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 result of your refractive state not being [[emmetropia|zero]]. | Your [[eye]] is a complex system of multiple layers of material with different [[refraction|refractive indexes]], all trying to project the great big wide world onto your tiny retina.

There are medical conditions that can accelerate near-sightedness or far-sightedness progression, so please see an [[optometrist]] or other medical doctor for an exam to be sure you don't have any medical issues. Just like you'd get your kid checked out if he was a little short for his age, but just focus on healthy lifestyle choices if his health was otherwise good. | There are medical conditions that can accelerate near-sightedness or far-sightedness progression, so please see an [[optometrist]] or other medical doctor for an exam to be sure you don't have any medical issues.
