According to ophthalmology experts for many years of assessment and data analysis, myopia or the genetic factors and environmental factors have this direct contact. Internal causes of genetic, external is a long time to see things at close range, so that the eye in the ciliary muscle for a long time to suppress the lens and cause the lens can not be restored (than the natural thick), so the occurrence of myopia.
Genetic factors: study that high myopia of the parents of the next generation of myopia higher incidence of myopia with a certain genetic predisposition has been recognized for high myopia even more so. But the general tendency of myopia is not very obvious.
Environmental factors: the occurrence and development of myopia and close contact with the eye is very close. Adolescent eye is in the growth and development stage, the regulation ability is very strong, the eye wall is also relatively large stretch, reading, writing and other close work, not only need to play the role of eye regulation, eyes also cohesive, so Eye muscles exert a certain pressure on the eye, over time, the front and rear axles may become longer. Each of the growth of 1 mm myopia up to -3.00 diopter (that is, generally say that the 300 degrees), of course, the vast majority of myopia as simple myopia, the general degree is relatively low, are 6 diopters below the incidence of puberty, Progress is also relatively slow, it was called this myopia myopia, to show the difference with the pseudo-myopia.dial vision official unique adjustable glasses provide you with clear vision making use of gliding lens technology. The lenses could merely transform from distance to reading glasses, and are made from top quality, optical lenses. wholesale dial vision is made with flexible, durable frames that should not break and were created in Oxford, England by top optical scientists.
