Should children go to the hospital with glasses?

There are two concepts, "optometry" and "glasses".

Children must go to the hospital for optometry, not to the optical shop. Why do you say that? Because children's eye adjustment is stronger than that of adults, it is necessary to relax the ciliary muscles with mydriatic liquid in order to obtain accurate optometry. Moreover, optical shops can't use mydriatic liquid medicine (otherwise it is illegal to practice medicine and heavy punishment is found). In addition, the hospital has professional instruments for measuring axial length, intraocular pressure and cornea. , you can comprehensively evaluate the eyeball situation and make it as close as possible to the objective examination results. Therefore, it is generally believed that people under 10 (whether wearing glasses for the first time or not) or 15 should go to the hospital for optometry. (There is an article "How Children Should Optometry" in Baidu Library, which is very clear.)

Let's talk about glasses. My point is that in hospitals, children can wear glasses instead of glasses. Why? The quality of glasses involves the following aspects: the accuracy of optometry data, the comfort of frames, the processing quality of lenses and glasses, and after-sales service. I will analyze one by one why I can't wear glasses in the hospital.

The accuracy of optometry data is the premise of precision machining. As mentioned above, children under 10 had better go to the hospital for optometry, because hospital optometry is more accurate objectively. Trust the hospital for optometry, or you won't know who to trust. However, the accuracy of hospital optometry does not mean that the glasses in the hospital are not defective, nor does it mean that the glasses in the optical shop have certain quality problems.

The comfort of the frame depends on the weight, material and size ... In theory, the lighter the better, the material should be soft and non-allergic, the angle of the nose pad should conform to the nose of the yellow race, and the size should be appropriate. Some parents and children think it is wrong to have a big and cool picture frame. The problem of frame comfort can go on and on, so far. What I want to say is that children's glasses are not medical devices, but actually a standardized commodity. Some brands and styles are available in hospitals and optical shops, and even more is better. For various reasons, glasses in hospitals are often out of date. Optical shops often purchase goods from the needs of real children such as styles, while specialized children's optical shops have many brands and diverse prices.

Lens. Lenses are also standardized commodities, which are available in hospitals and optical shops. Just like buying medicine in a hospital pharmacy, it's actually the same to go to the pharmacy with a doctor's prescription. Therefore, you can buy the same brand of lenses in optical shops, and the price is often lower than that in hospitals. It is not true that the lenses in the hospital are better than those in the optical shop. Indeed, the water in the lens is deeper. The wholesale price of Danyang lenses is as low as 10 yuan (this kind of lens has a high defective rate, so I really dare not use it for children, but only for adults). Which hospital and optical shop must be true, I dare not talk nonsense. My suggestion is that the merchant should write down the specific brand, variety and refractive index of the lens on the purchase voucher and ask for the lens packaging bag. I have always had doubts about buying a pair of frames and lenses around 100 yuan. Oh, dear! It seems to be beside the point again.

The quality of lens processing depends on the accuracy of glasses (this is the premise), the craftsmanship of the processing master and the processing equipment. The processing masters in optical shops can also be very skilled or even better than those in hospitals, and the processing equipment in optical shops can also be very good or even better than those in hospitals. Therefore, it is not true that the glasses processing in hospitals is better than that in optical shops.

After sales service. This is often overlooked by parents. Children's glasses have more wearing problems than adults, such as crooked temples, broken nose pads and worn lenses. In order to keep old customers, some optical shops have good after-sales service and laugh all over their faces (whether it is fake or true, at least better than the impatience of many hospitals). Orthopedic glasses frames and nose pads are free, and the second consumption can be discounted. It is not recommended to wear glasses online. There is no guarantee after sale, which will annoy you to death.

Price. On the premise of the same quality of frames and lenses, the price of optical shops is often cheaper than that of hospitals. This is because the optical shop is a market-oriented competition, and it can be sold with a little profit. The hospital seized the parents' confidence in the hospital (I don't feel at ease without wearing glasses in the hospital), and sold it at full price without discount. This is why many parents think that hospital glasses are expensive.

To sum it up. Try to go to the hospital for optometry if possible. An optician can go to a hospital or an optician's shop. You can take the optometry data issued by the hospital to the optician's shop (there is often no pupil distance on the hospital optometry list, and the optician can measure it). The optician should try to choose a professional chain, and there are many styles of children's glasses.
