Eye protection method

Adolescents have been over-applying their eyesight for a long time, resulting in too much mediation, resulting in excessive eyesight, long-term cramps in the ciliary muscles, resulting in a continuous increase in the lens, and symptoms of myopia, called pseudomyopia or accommodative myopia. . If not treated in time

Treatment can change from pseudo to organic myopia.

Mr. Yao Yong, the inventor of medical equipment senior engineer and double fog medical drug therapy device, believes that the main reason for students' myopia is that the school is overburdened. With the popularity of TV, video game consoles and computers, they have been watching with adults since childhood. Looked bad eyes. At present, the prevention and treatment of myopia products have their own characteristics, but most of them are unsatisfactory. It is necessary to try to take comprehensive treatment of Chinese and Western medicine, strengthen the treatment, and produce a polymerization effect, in order to be effective.

2. What is refractive error (or refractive error)?

For some reason, such as the change in the length of the eyeball, or a change in the refractive power of a part, so that the parallel light 5 meters away into the eyeball, the resulting imaging focus is not on the retina, but in front of or behind the retina, and some It doesn't matter at all. This kind of eye is called non-correction, also called refractive error. Myopia, hyperopia, and astigmatism are collectively referred to as refractive errors.

3. What is the difference between pseudomyopia and true myopia?

The so-called pseudo myopia is that the eye axis of the eyeball is normal, only because the continuous contraction of the ciliary muscle is over-regulated, and the regulation of sputum is formed, and visual fatigue symptoms such as eye swelling, dizziness, and decreased vision are observed, or the refractive power of the eye is enhanced. To make the eyeball in myopia, we call this myopia as pseudomyopia or accommodative myopia. It is not that this kind of myopia is fake and does not exist. It is said that the eyeball is normal, but the ciliary muscle tendon causes problems in the regulation function. If it can be found early, adhere to the principle of grasping from the early, grasping the principle of "small", timely relieve the visual fatigue, and relieve the ciliary muscle spasm. Healed. The use of double fog optotherapy eye treatment instrument for the treatment of pseudo myopia, a course of treatment can be cured. If pseudo-myopia is not treated in time, the ciliary muscle tendon is too long, and a permanent change is formed. The lens will always be in a state of increased convexity, resulting in an increase in the anteroposterior diameter of the eyeball (normal eye diameter of the eye is 24 mm). , each time the length of myopia is increased by 300 degrees, it develops into true myopia.

4. The treatment of high myopia and its genetic characteristics

High myopia refers to myopia beyond 600 degrees per eyeglass. Viewed from the outside of the eye, the anteroposterior diameter of the eyeball becomes longer and the eyeball is convex. At the same time, the fundus may have vitreous liquefaction, retinal choroidal atrophy, papilledema and other diseases. Therefore, high myopia is also called pathological myopia or degenerative myopia. Therefore, patients with false myopia and true myopia below 600 degrees should pay attention to eye hygiene, protect their eyes, and treat them early to prevent development of high myopia.

Genetic factors are one of the internal causes of myopia, which has been recognized by everyone. According to statistics: both parents are highly myopic, the probability of children suffering from myopia accounts for 97.3%, and the phenomenon of myopia occurs before the age of 12, and often develops in the direction of high myopia. If a child can start using the double-fog drug eye treatment device for health care or treatment at the age of seven or eight, it can prevent the occurrence of myopia.

5. How to cooperate with reasonable dietary prevention and treatment of myopia

The growth and development of adolescents is inseparable from the constant replenishment of all necessary nutrients. According to research: the lack of calcium, protein, vitamin A, etc. can be the predisposing factors of myopia. The eyeball scleral tissue can become weak and weak due to lack of nutrition, and can not withstand normal intraocular pressure, resulting in the elongation of the eye axis and the formation of myopia. For example, excessive intake of carbohydrates can reduce calcium in the body. The reduction of calcium can cause the decrease of scleral elasticity and form myopia. Therefore, in order to prevent the occurrence of myopia, in addition to good eye habits, children should not be educated. Picky eaters. Eat more fish, shrimp, lean meat, animal liver -, cattle and goat milk, vegetables, beans, coarse grains and other foods, foods with high vitamin content.

6. Unacceptable visual acuity

If the visual acuity is lower than 1.0, it is not allowed to accept engineering driving, civil aviation navigation control, marine fishing, marine fishery resources, marine engineering, precision instruments.

One eyesight is below 0.7. Can not take the aviation machinery, ship machinery, surveying and mapping, printing technology, art dance, film, drama, drama, music and other majors.

The sum of corrected visual acuity of both eyes is less than 1.4 (one eye corrected visual acuity is not less than 0.4), or deep myopia. If the degree of each eyeglass lens is greater than 600 degrees or the difference between the two eye corrected vision lens degrees exceeds 300 degrees, the engineering degree cannot be admitted. , science (except mathematics, theoretical physics), agricultural science, forestry, medical science (after the correction of dental majors, the visual acuity of each eye is not less than 0.8), sports, art and other majors

7. How to prevent myopia?

Prevention of myopia is a complex and comprehensive measure that includes reducing the student's academic burden, adhering to close eye hygiene, work and rest, and physical exercise. The main contents of eye hygiene are: one finger (3 cm) from the tip of the pen while writing; one punch (5-7 cm) from the chest; the distance between the eye and the book is one foot (33 cm); the sitting position is correct; Ensure sufficient illumination from the left front; continuous reading or reading or watching TV should not be too long, every hour should take a break, look far away or carry out outdoor activities for a while; insist on doing eye exercises.

8. What are the hazards of binocular parallax?

If the binocular parallax is greater than 250 degrees, it will destroy the eye's binocular single vision function. Over time, the eye with poor vision will develop into amblyopia or strabismus.

9. What are the factors that affect myopia treatment?

(1) Lack of awareness of the etiology and harm of myopia;

(2) improper selection of treatment methods and instruments;

(3) lack of confidence and perseverance in treatment;

(4) Can the correct use of treatment methods;

(5) Can you actively cooperate with treatment (A: change bad eye habits; B: cooperate with diet).
