There are many manufacturers producing amblyopia therapeutic apparatus in the market, and the varieties are really dazzling, but how should parents choose the amblyopia therapeutic apparatus suitable for their children? Next, we invite Professor Zhang from Zhongshan Eye Center to give us the following suggestions: 1. Choose according to the conditions: 1. For general amblyopia, choose non-light brush or 1~2 generation amblyopia instrument. 2. Amblyopia with myopic astigmatism: such as mixed astigmatism or myopic astigmatism: more than 3 generations of compound amblyopia instruments should be selected. Because amblyopia needs to be cured as soon as possible to prevent this astigmatism from becoming myopia, more than three generations of compound amblyopia instruments have the functions of enhancing vision and preventing myopia (such as flying point vision, bifocal threshold vision, sensitive color light pursuit, inclined plane, stereoscopic tension icon, etc.), which can improve the curative effect and shorten the course of treatment. 3. Amblyopia is accompanied by high myopia, high hyperopia and high astigmatism: 4~ generation amblyopia instruments (preferably enhanced amblyopia) should be selected, because: this kind of amblyopia is refractory amblyopia, and vision can be greatly improved only by using high-precision and enhanced compound amblyopia instruments; 4. Amblyopia with eye diseases: such as strabismus, nystagmus, cataract, glaucoma, etc. 4~5 compound amblyopia instruments should be selected. This kind of amblyopia is a curing amblyopia, which needs intensive and high-precision amblyopia instrument. 5. Amblyopia with myopia, that is, myopic amblyopia: it is appropriate to use more than 3 generations of compound amblyopia instruments. Because myopic amblyopia belongs to refractory amblyopia, it needs to be cured as soon as possible to prevent amblyopia from aggravating myopia. More than three generations of composite instruments have high precision, enhanced vision enhancement function and strong myopia prevention function, which can quickly cure amblyopia and minimize the development of myopia. Note: In order to raise the price, some manufacturers deliberately named the comprehensive amblyopia instrument with only 1~2 generation function as the third, fourth or fifth generation amblyopia instrument at will to increase the price by 1.5~3 times. In fact, it only has 1~2 generation function. Because more than three generations of products must have the functions of improving vision and preventing myopia, such as moving visual standard, moving color standard and tension stereoscopic icon (such as flying point visual standard, bifocal threshold visual standard, color light pursuit of sensitivity, inclined plane and stereoscopic tension icon). At present, similar products from other factories do not have these functions, and the "compound amblyopia instrument" does not have the function of preventing myopia and increasing memory in medical registration. At present, only the compound amblyopia instrument in China has an open first-generation standard and more than three generations of products. 2. Choose according to the number of functions: the curative effect of amblyopia instrument is related to the number of functions. Usually, the more functions, the better the effect and the higher the price. Therefore, refractory amblyopia should choose an amblyopia instrument with the function of 10 or above. At present, only the third generation amblyopia instrument has the visual enhancement function of more than 10. In addition, almost no similar products from one manufacturer can achieve the function above 10. In order to realize the function of 10, some factories even deliberately count "checking the internal vision" as an enhanced function. As we all know, checking eyesight has no enhancement effect, which is obviously misleading parents. Note that in order to increase the price by more than 2 times, some manufacturers deliberately regard "checking the internal vision" as a visual enhancement function, which is misleading. In fact, at present, there is no similar product that can achieve the function of 10 or above except for more than three generations of "compound amblyopia instrument". The price of amblyopia instrument is related to the number of functions, whether it is accompanied by the functions of enhancing vision, preventing myopia and increasing memory. Because the more functions, the more ways to improve vision, the more channels to improve vision. At the same time, it can ensure that the content of children's treatment is different every day, and it is always fresh and highly focused to get better results. Because the amblyopia instrument is composed of many optical lenses and special light sources, each additional function will increase the production cost. So the more functions, the more expensive it will be. Usually, the price of amblyopia instrument with 10 function is about 2000 yuan (except enhanced). Note that some manufacturers regard "in-machine visual inspection" as an additional function in order to increase the number of functions at a high price, misleading parents. As we all know, checking eyesight cannot improve eyesight, so it is not a function of improving eyesight. The price of amblyopia instruments is related to the number of functions: generally, amblyopia instruments with functions below 10 should cost less than 2000 yuan/set, but some manufacturers sell them for 3000 ~ 5000 yuan/set, not because of the high production cost, but because manufacturers give high discounts to middlemen in order to attract dealers to promote their products more. As a result, the child's parents were hurt. Therefore, when purchasing an amblyopia instrument, we can know the approximate price range of a certain amblyopia instrument by counting the number of functions of different manufacturers, and it is easy to buy a cost-effective amblyopia instrument. 3. Don't easily choose the amblyopia instrument according to the price. Except for a few more formal amblyopia instrument manufacturers, most amblyopia instruments will not publish "clear price tag". Obviously, the reason for not quoting is to give dealers more room to raise prices. Therefore, the intermediary can completely describe a first-generation and second-generation amblyopia instrument of about 2000 as 3-5 generations, and the price can be as high as 3000-5800 yuan, and then make a 20% discount to make parents happy. Parents who don't understand the market often pay 1-2 times the price, and the most important thing is that the amblyopia instrument they bought can only reach the second generation or less, which is not helpful to children with refractory amblyopia.
