Resolve a doubt

The more expensive the childrens eyeglasses, the better

In general, eyeglass lenses have different refractive indices. The higher the degree, the higher the appropriate refractive index, and the price will also rise. Different brands, different series of lens prices are also different. Wang Yanxia, a senior optometrist at the optometry Center of Beijing Tongren Hospital, said that price is not the only standard to measure the quality of glasses, and high-priced glasses may not be the best choice.

"For children, the key is to have accurate optometry." Wang Yanxia said that doctors will refer to the child's age, eye position, binocular vision function, eye habits and other multiple factors when prescribing optometry. It is unreasonable for some optical shops to make glasses only considering the degree. The glasses most suitable for my situation can obtain the best correction effect.

Huang Boss said that hospitals, roadside retail eyewear shops are from his store, the product is exactly the same, the difference is just the price, the bigger the brand, the greater the difference, the higher the profit. "A pair of titanium alloy frames sell 80 yuan here, which is 10 yuan, while brand retailers may be priced at 400 yuan." He said that most of the optician shops in optician City take the route of "small profits and quick sales".

"The rent of the shopping mall is 40,000 yuan a month, and the optical shops there can't survive the way we sell them." Huang Boss told reporters that in addition to the high cost of rent, the salaries of sales staff and optometrists are also added to consumers.

In addition, optician stores often undertake their own processing tasks, further reducing costs. Huang Boss admitted that there are many glasses factories in his hometown of Zhejiang, and he can not only directly take goods, but also learn the technology of processing glasses, including the processing and shaping of the frame and the mirror leg, the finishing of the connection of the frame and the mirror leg.

The reporter visited seven optician shops in Panjiayuan Eyewear City and found that a pair of 2000 yuan glasses in the brand eyewear shop, the same style here only needs four or five hundred yuan. If the customer does not choose the brand, it is not difficult to buy a pair of glasses within 200 yuan.

Tips

Children should dilate mydriasis and optometry for the first time

The child's first glasses must first be dilated optometry, rather than direct glasses. Myodatic optometry is a kind of medical behavior, that is, through drug relaxation regulation, only regular medical institutions have the qualification of myodatic optometry.

According to Wang Yanxia, the defocusing lens is designed to reduce the increasing external driving force of the eye axis during refractive correction. The length of the eye axis is directly related to the degree of myopia, and the speed of the eye axis is slow, and the degree of myopia is relatively slow. "If parents want to prevent the increase of myopia in their children, they can rationally choose defocus lenses as appropriate." Wang Yanxia stressed that the defocusing lens is not a "magic weapon" that controls the degree of myopia 100%, and no lens can fully control the degree of myopia, which can only slow down the rapid growth of myopia.

Anti-blue glasses do not prevent myopia, only dry eyes

Long-term use of electronic screens can affect tear secretion and cause dry eyes. Studies have shown that wearing blue-blocking glasses when using electronic screens may relieve dry eye symptoms.

However, for the prevention of myopia, Wang Kai, chief physician of the optometry Center of Peking University People's Hospital, admitted that there is no evidence that anti-blue glasses have the effect of preventing myopia, and there is no need to wear anti-blue glasses to prevent myopia in daily life. "First of all, beneficial blue light does not need protection. Only when the short-wave blue light energy is high enough, it can cause damage to the retina. This high energy blue light is not normally present in everyday life."
