How is myopia explained in medicine?

Myopia refers to a refractive state in which parallel light rays from 5 meters away enter the eye and focus in front of the retina, that is, the far point moves closer to the eye in a state of adjustment and rest.

There are many reasons for the formation of myopia 1Genetic factors, one parent has myopia, the heritability is 50%, both parents are myopia, the heritability is 100%.

2.Environmental factors, children are too stressed to study, and outdoor activities are reduced.

3.Excessive eye use at close range, such as eye habits, reading, studying, electronic products, etc., causes visual fatigue and myopia over time.

4.Due to physical reasons, children with thin bodies are more likely to be myopic.

5.Eating habits, picky eater, like sweets and fried foods.

6.Traumatic factors can cause myopia.

Hazards of high myopia:1Retinal detachment.

2.Vitreous opacity (commonly known as floaters), liquefaction of the vitreous.

3.Macular degeneration, posterior scleral staphyloma, peripheral retinal degeneration.

4.Leopard-shaped fundus.

5.Cataracts, glaucoma, etc.

Correction methods for myopia:1Eyeglasses.

2.Orthokeratology lenses.

3.Surgery**.

The regularity of the occurrence and development of myopia is still unknown, so the preventive effect of myopia is not obvious, usually pay more attention to children's vision care, reduce myopia is the focus of prevention work, regularly check children's eyesight, establish optometry files, early detection and early **.

1. The courses are different:

The four-year optometry program is a science degree, and the main courses include advanced mathematics, college English, ophthalmology, ophthalmology, applied optics, glasswork, binocular vision and a series of optometry courses, as well as anatomy, physiology, pathology and other basic medical courses.

The five-year optometry program is a medical degree, studying internal medicine, surgery, **science, pediatrics and diagnostics, and other courses should be similar to the four-year program, and you can take the physician qualification certificate.

2. The school year is different:

As for ophthalmology, if it is a major, the five-year clinical medicine undergraduate will not be so detailed, at least at the graduate level, or there will be a combination of bachelor's and master's degrees and bachelor's, master's and doctor's degrees.

I will not take those optical courses, mainly focusing on basic medical disciplines, ophthalmology and ophthalmology.

The technical layer family is different in order:

However, optometry is embodied at the theoretical level, while optometry technology is simply reflected at the level of applied technology. The courses of optometry and optometry technology are similar, but one is a four-year science degree and the other is a five-year program, and the only difference between the five-year program is that you can take the medical practitioner's qualification certificate.

In terms of development prospects and employment direction alone, there is not much difference between the two.
