Under the premise of refractive rest, distant objects cannot converge on the retina and form a focal point before the retina, thus causing visual distortion and resulting in blurred distant objects.

Wearing glasses for a long time can lead to inconvenience in life and work. Medium to high myopia can lead to protruding eyeballs and loose eyelids, affecting appearance. Restrictions on going to school, joining the military and finding a job. Myopic Arc: Genetic quality: Myopic Arc has a certain genetic tendency, especially for high myopia. If there is a genetic factor, the age of the disease is early, mostly above 6.00D. However, there are also people with high myopia who have no family history. High myopia is an autosomal recessive inheritance, while general myopia is a multifactorial genetic disorder. Developmental factors: Infants are farsighted because their eyes are small, but as they grow older, the eye axis gradually lengthens and develops normally by adolescence. This kind of myopia can develop and degenerate in later years, so the vision can be gradually reduced, and glasses cannot correct the vision. Rarely is myopia arc present at birth, but very few are congenital. Environmental factors: People who work in writing or other close work have more myopic arcs, as do adolescent students, and their prevalence rises significantly from the fifth or sixth grade onward.
