	Myopia - Wikipedia, the free encyclopedia
		Myopia is often induced this way in various animal models to study the pathogenesis and mechanism of myopia development.
		Measures of the heritability of myopia have yielded figures as high as 89%, and recent research has identified genes that may be responsible: defective versions of the PAX6 gene seem to be associated with myopia in twin studies [1].
		A diagnosis of myopia is typically confirmed during an eye examination by an ophthalmologist or an optometrist.

		Myopia, also known as nearsightedness or short-sightedness, is a refractive defect where the person affected usually can see nearby objects clearly but distant objects appear blurred.
		There is evidence of a correlation between shared genetic material and myopia, leading some to believe it is inherited (this is an example of the post hoc ergo propter hoc fallacy).
		Myopia is measured in diopters, which is the combined power of the cornea and the lens needed to focus distant images correctly on the retina.

	Nearsightedness (Myopia) (Site not responding. Last check: 2007-10-22)
		Myopia is rarely linked with headaches or eyestrain, as the eyes are naturally focused for near vision.
		With high myopia (-6.00 and up) one is at increased risk of glaucoma, retinal detachments and posterior vitreous detachments, so annual follow-up is recommended for those individuals.
		Myopia is very common and can be corrected by the use of appliances, such as glasses or contact lenses with a prescription, or by refractive surgery.
