Lavers goggles were successfully developed by introducing foreign advanced technology. According to the theory of visual physiology and the principle of gradient multifocal, the lens is divided into several optical zones [distance zone, near zone, gradient zone and deformed astigmatism zone]. The basic feature of this product is that there is a transition zone where the refractive power changes continuously between the fixed distance zone above the lens and the fixed near zone below the lens. This is the gradual change zone (function indication zone) of this product, and countless optical focuses gather in this zone, which is suitable for the needs of different visual changes of human eyes. With the function of near target simulating far target, the conversion process of accommodation power from near to far is scientifically integrated into a pair of lenses, so that students can use their eyes for a long time, such as reading and writing, and at the same time, through the automatic adjustment of eyeball by different optical focuses, induce the visual system to generate reverse accommodation power, cut off the source of myopia caused by myopia, effectively strengthen the exercise of ciliary muscle contraction function, eliminate visual fatigue, improve the refractive performance of lens, control the occurrence, development, improvement and recovery of myopia. In the production process, harmful light substances such as ultraviolet rays are added to the lens, which has the function of blocking harmful light and keeping children's eyes in a healthy visual environment at all times. The types and functional areas of vision glasses are shown in the following figure:
After years of clinical verification, "Lavers" ophthalmoscope is suitable for adolescent patients aged 6-23 years, and is applied to common binocular visual dysfunction such as insufficient accommodation, excessive accommodation, insufficient convergence, simple exotropia, simple esotropia, etc., which has a good clinical effect on amblyopia in children.
Lavers ophthalmoscope is divided into three courses, with two months as one course. After the vision is stable, it still needs to be worn for a period of time to consolidate (myopia is not a short-term treatment process). Here we require a 6-month treatment period and a 6-month consolidation period. Everyone has an adaptation period of one to two weeks for the first time. 2. Comparison between products and competitive products
[surgical therapy]:
In recent years, radial keratotomy, excimer laser keratectomy and in situ keratomileusis have appeared one after another. Corneal surgery has certain age and degree restrictions. Teenagers' eyes are not fully developed and mature, and their refractive state changes greatly, which is unstable and unsuitable. For radial keratotomy, there are many complications, such as corneal irritation, glare and iridescence, corneal opacity, corticosteroid glaucoma, astigmatism, corneal hypoesthesia and so on, so it is rarely used. Excimer laser keratectomy is limited by age and degree, and there are also some complications, such as corneal opacity and postoperative high intraocular pressure. In addition, the operation is expensive and not suitable for every patient. In short, any operation is both a process of treatment and a process of creation, so surgical treatment should be treated with caution. Professor Xu Guangdi, the leader of the expert group on prevention and treatment of myopia for students in China and a famous ophthalmologist, quoted the late ophthalmologist Professor Li as saying: "At present, these operations are effective methods to treat myopia. However, these treatments did not start with solving the cause, nor did they treat the diseased site, but operated on a healthy cornea. " Many ophthalmologists think: "Corneal surgery is not the development direction of myopia treatment, no matter from the perspective of economy or risk."
["ok" mirror]:
"OK" lens is a new contact lens in recent years. It mainly changes the curvature of cornea by pressing the cornea, thus changing the refractive state and treating myopia. There are certain age and degree restrictions. We can only mechanically compress the cornea to change its optical condition, but we can't change the pathological process of myopia. Moreover, young myopia patients can not strictly clean and disinfect lenses, and correctly take and wear them. If the disinfection is not strict, or the cornea is accidentally damaged when taking off the glasses, it may cause keratitis, corneal ulcer and even blindness. After OK therapy entered the China market, experts were cautious about it. They said: I haven't seen the official academic report on OK therapy. According to the feedback from colleagues who have tried this method, it can really take effect in a short time, but it can't fundamentally relieve corneal refraction. After treatment, the affected eyes can recover quickly and their vision will decline again. All CCTV and newspapers have issued warnings. )
[vision care]:
At present, there are many vision care instruments on the market, which mainly massage the eye points by watching the far and near images in the instruments, so as to relieve visual fatigue. It has a certain effect in the short term, but it takes time to treat every day, and the temporary effect will be offset by long-term eye fatigue, and the rebound phenomenon is serious. Time and time again, the seeker loses confidence in the treatment.
[Double lens]:
A pair of glasses with myopia and presbyopia can't see clearly the middle distance between the far and near areas, and the far and near areas have a sense of jumping, which can't meet the needs of viewpoint change. There is an obvious visible boundary between the far and near areas, which affects the natural beauty and has long been eliminated. More importantly, the patient does not want to see the treatment through the near zone, but sees things through the nearsighted part of the lens, so that the treatment effect cannot be achieved.
Comparison with monocular myopia glasses;
Myopia Wearing ordinary monocular myopia glasses only plays an optical correction role in ametropia, which can not meet the needs of the change of human eye viewpoint, and has the disadvantages of aggravating visual fatigue and deepening myopia. No matter how long it is worn, it can't achieve therapeutic effect.
[lovers]
The product adopts the principle of progressive multifocal, which is suitable for the change of different viewpoints of human eyes in close-range environment, simulates the function of distant target with near target, automatically adjusts the eyeballs with different optical focuses, cuts off the root of myopia, strengthens the exercise of ciliary muscle contraction function, eliminates visual fatigue, effectively controls the occurrence and development of myopia, and improves and restores vision.
Based on the abnormal phenomena of binocular visual function such as insufficient accommodation, accommodation fatigue, excessive convergence, pseudo-insufficient convergence, simple esotropia, exotropia, excessive divergence, etc., the key to treating myopia is grasped, and students can receive treatment directly while using their eyes. Myopia caused by learning eyes is still recovering at noon, and the treatment time is equal to the time of using eyes, which avoids taking time out for treatment every day and using temporary curative effect for a long time again.
The clinical results show that the product is suitable for adolescent patients aged 6-23 years, and has obvious curative effect on preventing and treating myopia. It is purely physical therapy and has no side effects. The quality of the lens is guaranteed, and harmful light-shielding substances are added in the production process to avoid the stimulation of harmful light to the eyes, so that the eyes are always in a healthy visual environment.
3. Frequently asked questions
Q: Can Lavers goggles really treat myopia, improve and restore vision?
It can be affirmed that "Lavers" ophthalmoscope can fundamentally solve the problem of vision decline, prevent and control the occurrence of myopia and the development of myopia degree, improve and restore vision after years of clinical verification, with remarkable curative effect. If a patient wears myopia glasses for many years and his eyesight is poor, first inform him of the disadvantages of wearing myopia glasses (myopia glasses only play an optical correction role for eye ametropia, no matter how long they are worn, they have no therapeutic effect, and they have the disadvantages of aggravating visual fatigue and promoting the wearer's myopia to deepen year by year, so they can't do without glasses from now on. Moreover, the child is in the period of growth and development, and the eyeball has not yet matured, which can be repaired by some good therapeutic products. The focus is recognized by ophthalmology. If the parents of myopia patients are nearsighted, ask them: What was your degree at that time? How much is it now? Parents who experience the pain of increasing myopia can often convince each other from the "control" effect of the product.
In addition, the consultant should be informed that it is impossible to restore normal vision with high true myopia (which is well known). Therefore, for this kind of patients, it can generally be increased by half (for example, the myopia of -400 degrees can be reduced to about -200 degrees), which makes the consultant feel that we have achieved integrity and enhanced his or her trust in us.
Q: When can we see the effect, that is, the curative effect?
In terms of adaptation period, people who adapt quickly will get results quickly (generally, the adaptation period is one to two weeks); Judging from the degree of myopia, compared with low myopia, high myopia takes effect slowly; Judging from the history of wearing myopia, people who wear myopia for a long time have dependence on myopia, but their adaptation is relatively slow and their effectiveness is slow. The combination of the three answers, in short, is to let customers know that myopia itself has certain complexity, is a "chronic disease" and needs a non-short-term treatment process. The treatment is divided into three courses, with two months as a course of treatment and a consolidation period of six months.
Q: Is there an age limit for wearing this product? Can everyone wear it?
This product is suitable for myopia patients aged 6-23. In fact, not everyone is suitable for students to wear "Lavers" glasses. Patients with inner ear diseases may have dizziness, vomiting and other symptoms because they can't tolerate the slight deformation of vision, which is difficult to adapt in a short time and the adaptation period is longer than that of ordinary people.
Q: Does this product have any side effects?
The product is a second-class "quasi-"medical device, which adopts pure physical therapy and does not touch the human body. After years of clinical verification, it is safe and has no side effects.
Q: A popular customer phrase is "How to match"?
The dress code is very strict. Our technicians will optometry and measure the pupil distance for patients free of charge, and then fit them according to the measured data. (Reflected in the gradual change from the treatment area to the near area).
Q: How to use it (that is, how to wear it)?
This product is basically similar to myopia glasses, but the wearing method is much stricter than myopia glasses. From the perspective of various optical zones, the wearer needs to actively cooperate. From the time point of view, it only needs to be worn for three to four hours a day at the beginning of adaptation. During the treatment after adaptation, it should be worn for 6 to 8 hours every day as long as it is used for short-distance learning.
Q: Do you need to change your glasses when your eyesight is improved (will this degree not adapt to your child's eyesight)?
This product can automatically adjust the focus of eyes, which is conducive to the gradual recovery of vision, so there is no need to change glasses, just a pair.
Q the child has used many therapeutic products before, and the results have no effect. What is the efficacy of this product?
Many therapeutic products need to be taken 15-30 minutes every day for treatment. The short-term effect is good, but it is not lasting, and the rebound phenomenon is serious, mainly because the temporary effect is offset by long-term eye fatigue. Time and time again, the patient lost confidence. "Lavers" goggles are used by students for a long time while they are involuntarily receiving treatment, and they unconsciously improve their vision treatment. Myopia caused by long-term use of eyes will gradually improve and restore vision, and the effect will be more lasting and strong.
Q: Is there any reliable guarantee for "Lavers" goggles?
"Lavers" goggles filled the blank of optometry and obtained two national patents [patent number: ZL 99254419 ×, ZL 99255500.0]. Approved by Jiangsu Drug Administration, it is registered as a second-class quasi-brand instrument, tested and approved by Medical Device Quality Supervision Center of National Pharmaceutical Products Administration and Institute of Optical Radiation of Zhejiang University, and won the honor of China consumers' trustworthy shopping quality and recommended by China Women and Children Career Development Center. After years of clinical verification, it has no side effects and can be worn with confidence.
Q: Can "Lavers" goggles replace myopia glasses? Can you see the blackboard in class?
"Lavers" goggles are therapeutic glasses, which have no myopia. They can be used alternately with myopia glasses in class without affecting the overall therapeutic effect.
Actually, I also use it. The introduction method is someone else's.
When watching TV, it will be very tiring to hold the lower bar high with the lowest lens, but if you bear with it, your eyes will soon drop by 50 degrees. It is best to watch TV for the first time for more than 2, 3 to 5 hours. The first time I watched TV for 4 hours, or even for a week, my eyes dropped by 50 degrees. I'm afraid to use the upper-middle lens to see the degree again this week. I shouldn't wear glasses. If I can't see clearly, I should hold my head high and read.
Give my opinion: I just don't increase my degree, nothing else.
