Myopic auto-flip mirror
I. Introduction
Automatic flip mirror is a new generation of efficient myopia enhancement control mirror invented by Professor Liu Dongguang, a graduate student of Sun Yat-sen University ophthalmology, a famous myopia expert and winner of more than 50 patents, who improved the manual flip mirror of Professor Baez in the United States. It is composed of 2 pairs of punching lenses and intelligent control system. Through the flipping mirror, the focal point of adjustment will jump from the eyes to infinity and back to the eyes. Repeated training can improve the adjustment sensitivity and improve vision and control the development of myopia.
Second, the relationship between the main causes of myopia and the flipping mirror
The main reason for myopia is that 85% of myopia is caused by looking at the near and 15% is caused by the growth of the eye axis.
Flip-flop is to improve the adjustment sensitivity of looking near and far, to quickly improve the visual acuity and control the occurrence and development of myopia. It can adjust the sensitivity of the eyes by constantly looking at the near and far through the flipping mirror, so as to improve the visual acuity and control 85% of myopia caused by looking at the near eyes.
Three, flip mirror principle
The principle is that by improving the adjustment sensitivity of looking near and looking far, it can quickly improve visual acuity and control the occurrence and development of myopia.
Four, flip mirror features
1, a key operation: can read books, computers and games in the happy completion of the flip time
Frequency: automatic control, stable effect
2, the use of more than 2 weeks, can significantly improve the visual function of long-term control of myopia efficiency in more than 90%
3, an automatic flip mirror has 4 lenses (equivalent to 2 glasses), and another microcomputer control system. But its promotional price is only the price of a mid-range glasses (600 ~ 800 yuan), due to its control of myopia efficiency of more than 90%. Therefore, a flip mirror can make myopic students with more than 10 less myopic glasses, saving more money.
Five, the scope of application of the flip-flop
1, all kinds of myopia students at risk: such as reading more, writing posture is not good, watching TV, computer or playing games more; check myopia astigmatism or mixed astigmatism, or farsightedness less than 50 degrees;
2. Various myopic students.
(1)Those who are reluctant to wear glasses when they first suffer from myopia
(2) Those with rapid myopia development
(3) Young children with myopia, or those with one parent who is highly myopic;
(4) People with high myopia with eye convexity, or with fundus pathology;
(5) Myopic amblyopia, or amblyopia with myopia.
3, various eye fatigue syndrome
Sixth, the history of flip-flop development
At the end of the last century, a popular myopia training method in the United States has shaken the world of ophthalmology, that is, the famous American myopia expert Professor Baez invented the adjustment sensitivity training method, whose core principle is to improve the focus sensitivity (i.e., adjustment sensitivity) of myopia patients looking near and far through two kinds of apparatus training, so as to quickly improve visual acuity and control the occurrence and development of myopia.
Based on the principle of Baez training method, Soviet experts observed more than 200,000 students for more than 10 years and found that the incidence of myopia among students who did daily adjustment sensitivity training was only 1/10 of those who did not train, proving that adjustment training method is a very effective myopia control method for students.
At the beginning of this century, the Zhongshan Eye Center, a national key laboratory for myopia in China, in collaboration with several universities in the United States and Australia, studied the pathogenesis of myopia through monkeys and further confirmed that “regulatory lag” is the key link in the development of myopia. It was suggested that training in accommodation sensitivity could effectively prevent the development of myopia in students.
