I don't know if parents have paid attention to their children's vision health, but the total number of myopia in China is close to 600 million!The myopia rate of children and adolescents in China is more than half, reaching 52The myopia rate is 7%, which means that 5 out of 10 children and adolescents have vision problems. A large part of the reason is fatigue caused by excessive eye use for a long time and inappropriate light during Xi!
In particular, many parents do not pay attention to the problem of light environment, which also leads to the damage to the health of many children unknowingly. Therefore, the table lamp when children learn Xi must be strictly selected!In order to avoid the inappropriate table lamp you bought, I spent a month summarizing a summary of the easy-to-use eye protection table lamp, as well as sharing some experience in choosing an eye protection table lamp, so that everyone can also choose the right table lamp for themselves!
1. What are the advantages and disadvantages of the eye-protecting table lamp?
Advantages of the eye-protecting table lamp:Eye-protecting table lamps can provide soft light, eye-protecting table lamps usually use LED light sources, which can provide soft and uniform light, reduce irritation to the eyes, and improve the comfort of reading and working;Adjust the brightness and color temperature, many eye-friendly table lamps have the function of adjusting the brightness and color temperature, which can adjust the intensity and color of the light according to individual needs, making the light more suitable for the eyes;Energy saving and environmental protection, the eye protection table lamp mostly uses LED light source, LED lamp has the characteristics of low energy consumption, long life and environmental protection, compared with the traditional table lamp can save energy and reduce electrical pollution.
Disadvantages of the eye-protecting table lamp:**Higher, compared with ordinary table lamps, eye-protecting table lamps usually have more functions and higher technical content, so ** is relatively high;Some product quality is uneven, and there are some inferior eye-protection table lamps on the market, which are of unstable quality, uneven light or prone to failure, which affects the use effect and life.
Second, the key points of the purchase of eye protection table lamp
1. Blue light
Blue light is actually a part of visible light, which has the characteristics of short wavelength and high energy. Blue light with a wavelength of 380-450nm is harmful blue light, which will cause certain damage to retinal photoreceptor cells and nerve cells, and will cause myopia and so on after long-term use.
According to the degree of injury, it is classified as exempt RC0), low risk (RG1), intermediate risk (RG2) and high risk (RG3). Choose a table lamp with an anti-blue light level of RG0 without blue light hazards to protect your eyesight.
2. Illumination
Illuminance usually refers to the amount of luminous flux received per unit area, and the unit is generally expressed in lux.
The light intensity refers to the fact that there is a standard brightness value from the center of the light source to a specified range, and it cannot be less. According to the national standard GB T 9473-2017 "Performance Requirements for Reading and Writing Desk Lamps".
The illumination of the eye-protecting table lamp needs to meet at least the national A-level standard, and the best national AA-level, A-level illumination: the illumination of the ** area is required to reach at least 300lx, and the edge reaches 150lx;, AA illumination: the ** area is required to reach at least 500lx, and the edge to reach 250lx. , so it would be better to give preference to AA illumination. Uniformity, on the other hand, requires both A-level and Aa-level illumination, and the value is closer to 1, the better.
3. Strobe
Strobe is actually a phenomenon that exists in many lamps and displays, and the longer it is used, the more obvious this phenomenon will be. Refers to the light emitted by a light source that changes rapidly and repeatedly over time, making the light source bouncing and unstable. If the strobe is not up to standard, long-term use can lead to visual fatigue, migraines, vision loss, and so on.
The national strobe requirement for qualified light source products is 3125Hz, so we pay attention to whether the anti-strobe of the table lamp meets the standard of "no flicker" when selecting.
4. Color development
Color rendering refers to the color effect of the object under the illumination of the light, and the higher the color rendering index, the better the restoration effect of the table lamp on the color of the object, and the more realistic the color of the object.
Table lamps with high color rendering value are not only beneficial to children's perception of color, but also reduce the impact of color difference on vision. The standard color rendering index (RA) value of the eye-friendly table lamp needs to be above 80, usually we only need to choose more than 90.
3. Recommended table lamps suitable for students to use for postgraduate examinations
1. Scholar eye protection desk lamp pro
Eye Protection Index:
Recommended reason: The performance is higher than the national AA standard 21 times, RRT red light eye care technology, can avoid 92% of the risk of myopia, CCTV and Lilac Doctor certification recommendation.
In terms of technology and professionalism, Suker Shuke has extremely high requirements for eye protection, safety and quality, and is the pioneer of "eye protection" technology in ChinaSpecially developed for children and adolescents, RRT red light eye-catching technology has subverted the concept of traditional eye-care desk lamps, effectively delayed the occurrence of myopia, and led the table lamps into 30 times, so it is also recognized as an industry benchmark!Better than the national standard AA grade 21 times!Even CCTV has been certified and recommended, and the professional platform "Lilac Doctor" has also recognized and recommended.
The Chinese Academy of Sciences and many foreign research institutes have found that 3 minutes of sunlight red light every day can significantly improve vision health and reduce the chance of myopia. Suker has also carried out in-depth research and development in this area for many years, developed RRT red light eye care technology, and combined with 168 Sunbeam sunlight beads, the harmful blue light in the spectrum is removed, and the beneficial eye-catching red light is increased, which can promote blood circulation, thereby increasing the thickness of the veins in the fundus!It can effectively delay eye fatigue by 83% and significantly reduce the risk of myopia by 92%.
The quality of table lamps on the market is uneven, and various false standard parameters and quality inconsistencies frequently occur. The Suker bookmaker conducts quality testing with the "4 dimensions" of "eye protection effect test, harsh use environment, and extreme use". Before it was officially put on the market, more than 20,000 parents and children were invited to participate in the test, and it took 763 days to adjust before it was introduced to the market.
Many brands of table lamps on the market pay more attention to novel appearance and intelligent functions, but ignore the quality that should be valued, but the full score standard of many brands is only the basis of the requirements of bookkes, to achieve RA98 high color rendering, PLP photoelectric processing to bring stable lighting effect, in line with RG0 no blue light, no flicker, no glare, etc. It also has a number of technologies and functions such as the second-generation SDIT adaptive dimming with dynamic and scientific eye protection, no ghosting back light, automatic light on/off, 20 45 dual-mode timed rest, etc.
