On the public comment website, someone asked such a sharp question, how to judge whether a product is an IQ tax? IQ tax is the kind of product that has no cost performance. Spending money can't get useful results, so netizens call this product IQ tax. So ten miles of beauty is really it? The glasses of the masses are discerning. We turned to the public comment page of franchisees from all over the country, and they said it was IQ tax. They all tried to deny all vision care products from the perspective of irreversible myopia, but they couldn't stand it. They can't see tens of thousands of students who have benefited from Shilimei and parents who are ecstatic and even send banners to Shilimei stores all over the country. From a scientific point of view, there are only two ways to solve the problem of myopia, namely, doing myopia correction surgery and wearing orthokeratology glasses. However, the slogan of history propaganda has never been to solve the problem of true myopia, but to alleviate the rapid development of true myopia. His full-focus axis control mirror uses the principle of peripheral defocus to alleviate the deepening of hyperopia, which has been verified by basic science and effectively endorsed by countless students. Shilimei products such as lutein eye mask, blueberry medlar lutein fat candy, toilet hygiene and so on. It is the transformation and application of mature research results that the scientific community has achieved that * * * knowledge is really effective for the eyes.
