Long-term facing computer and mobile phone screens, many people will choose to prevent blue-racer lenses; when glasses, for fashion shows, there are still many people who choose large frame glasses. Recently, the Chinese Consumer Association (hereinafter referred to as the Sino Consumer Association) “2019 Mirror Comparative Experimental Experiment Report” Anti-blue glasses should also be cautious. I heard this news, many netizens launched and fashionable, and should not choose blue glasses when entangled with the glasses. In this regard, the reporter consulted the relevant expert.
The size of the frame cannot be “decided”
On September 18, China Consumers Association released the “2019 Mirror Comparative Experiment Report”. The report suggests that consumers should choose the frame according to the mirror prescription.
Report reminder, consumers below 500 degrees, can choose a larger frame shape and size; the number of degrees at 500-800 degrees should try to select a smaller or half frame frame with smaller frame width; degree Consumers in more than 800 degrees should choose small full frame frames.
Miss Chen told reporters that her face is fat, generally choosing a large frame, it looks like a small appearance, and the small frame is not good. She doesn’t understand why she can’t match the large frame glasses.
On the morning of the 25th, the reporter visited several glasses stores. Shapingba Three Gorges Square, a chain optic store clerk, said that the degree of 500 degrees is generally not recommended to match the large frame, because the original film is thin, the four weeks thick, the larger the frame, the thicker, the lens is close to the edge of the frame, and it is not good to see At the same time, it will be slightly heavy, but it has no effect on the vision.
In the stone bridge shop, the boss said that the frame is not limited, mainly to see personal hobbies, if the number of customer chooses large frames, it feels heavy, it can be used with a high refractive index, but the price will be slightly expensive. Point.

Degree deep wear large frames are easy to cause optical center deviation
In this regard, the reporter interviewed the Ph.D. of the Army Military Medical University, Huang Yanming, the Ophthalmology of the Xinqiao Hospital, the Army Military Medical University, said that the general degree deep person does not recommend the large frame glasses. First of all, because the lens of the degree is relatively thick, the frame is large, the glasses are all more heavy, and it is easy to decline in the glasses, so that the deviation of the glasses optical center is easily caused. Second, most of the adult pupils are around 64mm, and the large frame will inevitably be angry during processing, which will easily produce prisms, which will affect visual quality.
Anti-blue glasses can’t choose casually
The reporter saw that the report also suggested that due to the current associated glasses standards, there is no provision for the blue-racer effect of anti-blue lens, and ordinary consumers cautiously select the blue-racer lenses. Special eye disease patients, such as macular diseases, patients with diabetic fundus lesions should choose to prevent blue-ray glasses based on ophthalmologists.
In the Shapingba Three Gorges Square, a large chain optical store, when the reporter advised the mirror, the clerk said: “You usually work more to the computer, it is recommended to choose anti-blue glasses.”
The clerk also said that there are a lot of guests with anti-blue glasses, and they will only have good deals in the eyes. In another glasses shop, the reporter gets similar results.
With anti-blue glasses should go to a regular institution
For anti-blue glasses, Army Military Medical University Eye Exception Master Zhang Huai believes that in addition to existing in natural sun, Blu exists in computer displays, fluorescent, mobile phones, digital products, display, LED and other rays. Generally considering short-wave blue light, there is a certain damage to the eyes, especially the oysterical macular area. Specifically, the case of eye damage, is related to the time of illumination, the intensity of the illumination, and the following habitual habit. In fact, Blu-ray has the effects of adjusting the role of biological rhythm, sleep, emotion, memory, etc., which is beneficial to the human body. Therefore, it is not a crowd of electronic products for a long time, anti-blue glasses are not very significant, but for a long time to the electronic screen, it is generally recommended to wear blue lens, but the quality of blue lens on the market is not Aligned, a parallel blue lens should block the harmful blue light while retaining a free blue light. So I suggest that everyone should go to a regular professional institutional.
Further extension: How to wear glasses correctly?
How to choose the right glasses with your own glasses, the above two doctors also give some recommendations:
First of all, the election frame is to match the face, the round face selects the thickness of the corner, the face selection round line soft, the triangle face selects the butterfly or round, the face is small, the long face is smashed, and the goose face Dai mirror is unlimited.
Second, to consider the number of refractive degrees, it is not recommended to select half frame and frameless glasses. Because the lens is too thin, it is easy to damage the lens during use, and the medium is not too much demand for the mirror frame, and the high refractiveness is try to choose refraction. Legile lenses (such as N1.67 or N1.74 refractive index) and generally do not recommend large boxes, half frames, and frameless frames.
