'''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. | |||
If your vision problems are entirely due to refractive state, your doctor will probably | 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]]. | ||
==[[LEGAL:NMA|Red:No medical advice]]== | |||
There are medical conditions that can accelerate near-sightedness or far-sightedness progression, so please see an [[optometrist]] or an actual 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. | |||
If your vision problems are entirely due to refractive state, your doctor will probably prescribe glasses that give a [[20/20 correction]]. At the point that you've been medically cleared and have a [[prescription]] you are ready to start the [[reduced lens method]]. | |||
