Most of the popular so-called “comprehensive amblyopia treatment instruments” are imitations of the multifunctional amblyopia treatment instruments invented by Professor Liu Dongguang (i.e., cottage versions). Because there is no basis for development, no patent technology certificate, the function and appearance are almost all copies of Dr. Liu’s amblyopia instrument patent products. However, many of the treatment techniques in amblyopia devices have been integrated into the experience of amblyopia experts, and these experiences cannot be copied by manufacturers. Therefore, the cottage amblyopia device may have many hidden dangers that are harmful to the eyes. For example, its labeled red flash is not a wavelength of 640 millimeters, its in-machine visual acuity table is not Professor Liu Dongguang’s patented technology threshold visual acuity table, etc., because the vision enhancement training function is very different from Professor Liu’s original. Second, comprehensive amblyopia treatment instrument its function is not comprehensive, clinically comprehensive amblyopia treatment refers to include wearing corrective glasses, cover the healthy eye, plus the comprehensive treatment of auxiliary vision enhancement instruments. Therefore, the comprehensive amblyopia treatment instrument should be renamed as multifunctional amblyopia treatment instrument. The existing comprehensive amblyopia treatment instrument is not suitable for amblyopia with high farsightedness, high myopia, mixed astigmatism, myopic astigmatism, strabismic amblyopia and other amblyopia that needs long-term treatment or easily turns into myopia. Instead, you should choose to treat amblyopia with a compound amblyopia treatment instrument with enhanced vision enhancement, myopia prevention and visual memory functions, which can prevent complications and improve the efficacy and shorten the course of treatment by more than half. Because: 1, structurally: comprehensive amblyopia instrument: glasses directly touching the lens – grinding glasses; new compound amblyopia instrument: bermed head type: anti-friction glasses and improve attention, provide anti-myopia device (distant chemical mirror, adjustment sensitivity instrument, etc.). 2, function: traditional comprehensive amblyopia instrument, only to treat amblyopia, amblyopia cured, only as waste discarded. Modern compound amblyopia instrument: in addition to cure amblyopia, there are memory enhancement, myopia prevention and other functions. After the amblyopia is cured, it can still be used for life. Help students to increase memory and prevent myopia. 3, price: traditional comprehensive amblyopia instrument: the best price in 3800 ~ 5000 yuan, functional level only 2 generations. While Dr. Eye’s compound amblyopia instrument: the functional level has reached 5 generations, although a variety of enhanced vision enhancement functions, visual memory and myopia prevention and other functions have been added. But the price is about half of the price of the same number of comprehensive amblyopia treatment devices. For example, the second generation of compound amblyopia treatment instrument has 10 functions, which is already more than the best comprehensive amblyopia instrument of other manufacturers (7~9), while the price is about half lower. 4, complications: comprehensive amblyopia instrument: it is easy to cause, aggravate myopia (because the amblyopia instrument is a long-term ultra close treatment instrument, can cause or aggravate about 1/3 amblyopic children myopia). Modern compound amblyopia devices: There are 2~3 kinds of anti-myopia devices on the lens or inside, which can effectively prevent myopia caused by long-term ultra-close viewing of amblyopia devices. Fourth, the “comprehensive amblyopia treatment instrument” has a particularly serious complication that parents should pay close attention to, namely, causing and aggravating myopia. Because: 1. Looking at the amblyopia device, like looking at a microscope, is a kind of ultra-close work. It is easy to cause and aggravate myopia. According to clinical statistics, treatment with a comprehensive amblyopia device for more than six months has a chance of causing and aggravating myopia of about 30% or more. Therefore, more serious amblyopia or myopic amblyopia or myopic astigmatism, mixed astigmatism amblyopia, etc., should be treated with comprehensive amblyopia treatment instrument with caution. 2, comprehensive amblyopia instrument within the gradient visual marker, is a kind of normal people are very difficult to see the miniature visual marker, such as no ophthalmology professionals to deal with, look at such a visual marker is very hurt eyes, it is easy to visual fatigue and cause increased myopia. The step visual marker in the comprehensive amblyopia treatment instrument without a patent certificate is very irregular, more likely to cause aggravated myopia, so parents choose amblyopia instrument, it is best to check whether the manufacturer has a patent certificate (available on the website of the China Intellectual Property Office, whether the original development of professionals or imitation cottage amblyopia instrument. 3, comprehensive amblyopia device does not have a device to prevent myopia: because watching amblyopia device is a “super close” gaze process. Therefore, there should be a device or instrument to prevent myopia and relax the eyes after looking at the amblyopia device or looking at it. The existing comprehensive amblyopia devices are not available, so they should be used with caution. Thus, for refractory or severe amblyopia that requires long-term treatment, it is not advisable to use a comprehensive amblyopia apparatus, but rather a modern compound amblyopia treatment apparatus.
