I. The occurrence and development of myopia in students is mainly related to the near reflex and the decrease in eye sensitivity
1.85% is related to the near reflex and decreased eye sensitivity
As a result of looking close (such as reading and writing at 750px), both eyes must use 300 degrees of regulatory myopia and gather inward in order to see the surface of the book (called the near reflex), such as long-term “look close” can also be secondary to a decrease in eye focusing sensitivity, narrowing of the visual field, resulting in intraocular biochemical changes and eye axis lengthening, causing the occurrence and development of myopia.
The closer the distance, the higher the regulatory myopia and the more severe the narrowing of the visual field. For example, reading a book at 750px can cause 300 degrees, 500px can cause 500 degrees, and 250px can cause 1000 degrees of regulatory myopia.
2.15% is related to the growth of the eye axis
The eye axis increases by about 300 degrees of myopia for every 1mm of growth. As the eye axis of children grows longer with growth, myopia in children can only be prevented but not cured, and will develop more or less.
Second, students myopia must be controlled as early as possible (without control there are the following hazards)
1, fast development, if the annual increase of more than 100 degrees, 10 years up to more than 1000 degrees of high myopia, about 1/4 will sooner or later occur in the fundus retinal hemorrhage, detachment, resulting in low vision, or even blindness;
2, high myopia can also cause amblyopia, “convex eyes”, lenses up circle, etc., can seriously affect the appearance.
Third, the best way to treat myopia is to use telephoto lenses
The main reason for students’ myopia is that they look too close, because it is impossible for students not to read books and computers. Therefore, their myopia is difficult to control with general methods. The more students read and study, the better they can rest their eyes and the less myopia is likely to develop.
Four, far-sighted glasses can offset 300 degrees of regulatory myopia, and will look at the near virtual look into the far
1, offset the role of myopia: the farsighted mirror consists of a convex prism virtual focal mirror, which contains 100 degrees of farsightedness and 4 units of prism degree to produce 200 degrees of virtual (negative collectivity) farsightedness, exactly to offset 300 degrees of myopia. For example, a student with 400 degrees of myopia can reduce 300 degrees by wearing a farsighted lens and read books and computers with the remaining 100 degrees of myopia, which will not allow myopia to develop. In addition, the prisms in the telephoto lenses can separate the eyes outward, thus enlarging the field of vision and offsetting the myopia development caused by the narrowing of the field of vision caused by near concentration.
2. Counteracting the experience of myopia: The lenses can counteract myopia in the same way that water can extinguish fire. The following lens through the test to confirm its role in offsetting myopia: the patient’s nearsightedness and farsightedness in front of the eyes, through the nearsightedness of the lens to see the object image will become smaller, moving with the movement, and through the farsightedness of the lens to see the object image becomes larger, appearing to reverse; indicates that the farsightedness of the lens can exactly offset myopia lens.
3, far from the experience: put on the far-reaching mirror to see about 1250px “bull’s-head color chart” (see the back cover of this booklet), you can see “red corner, red eyes, red nose, etc. protrude, while blue or green eyes, nose, etc., sink in the back, there is a clear sense of three-dimensional, is the far-reaching mirror will be” Near things” separate (virtual look far) to form the result of parallax.
V. The object of application, use, side effects and effects
1, suitable for slowing down the occurrence and development of any degree of myopia (including astigmatism myopia, etc.) or preventing myopia in students without myopia.
2.A pair of telephoto glasses can be used for any degree of myopia (including astigmatism, etc.), and can be used for more than 10 years without changing.
3, it is only worn when reading and studying, usually or out activities do not need to wear, does not affect the appearance, and no other side effects.
4, more than 50,000 cases of clinical observation to confirm the efficiency of more than 85%, up to control the development of myopia within 0 ~ 25 degrees per year.
