As academic pressure increases, students spend more and more time on homework, and the burden on their eyes increases.
If we want to better protect children's eyes, we must not only let children maintain good eye habits, but also try to provide children with a better lighting environment, especially the eye-protecting table lamp used by children for homework, we must choose well.
So, what kind of eye protection table lamp is better for children's eyes? How should I buy it?
First, the eye-protecting table lamp should be chosen in this way
1. Look at the color rendering
Desk lamps with too low color rendering cannot be bought. Because this kind of light cannot make the object show the real color, it will increase the burden on the eyes, make the child more prone to eye fatigue, and will also affect the child's ability to recognize color, and even lead to color weakness in serious cases.
Specifically, when buying a table lamp, we have to look at its general color rendering index Ra, as well as the index R9 for saturated red, the maximum value of both is 100, the closer to 100, the more it can restore the true color of the item.
The relevant standards stipulate that a qualified table lamp must ensure Ra>80, R9>0. The eye protection table lamp for children should try to have better data, and it is best that Ra and R9 are greater than 90.
2. Look at the lighting ability
The table lamps we buy for our children must not only ensure that the brightness is high enough, but also ensure that the light is evenly distributed.
Human pupils are very sensitive, constricting when they see bright light and dilating when they see dark places. If the light of the lamp is uneven and there is a clear contrast between light and dark, it will cause the child's eyes to adjust frequently, resulting in eye fatigue.
The national standard stipulates two photometric levels of grade A and grade AA for the illumination and uniformity of table lamps, and AA grade is better.
The eye protection lamp we choose for children must meet the AA standard.
3. Look at the color temperature
Color temperature affects the color of the light, with lights with low color temperature being yellowish and lights with high color temperature being blue.
Relevant studies have shown that the best color temperature for children to write homework should be 4000K. The light at this color temperature is not actually white, but slightly yellow.
If the color temperature of the desk lamp is too high, it will cause the blue light dose in the light source to exceed the standard, bringing the harm of blue light that cannot be ignored. Not only can it damage your child's retina, but it can also cause insomnia.
We want to choose those table lamps with a fixed color temperature of 4000K, or slightly lower than 4000K. If you buy a desk lamp with adjustable color temperature range, be sure to adjust it to below 4000K when your child is doing homework at night.
4. Look at blue light
Nowadays, lamps and lanterns will have a blue light level, divided into RG0 to RG3, in fact, RG0 is the safest, also called exempt level.
The eye-protecting table lamp we buy for our children must be RG0 level.
5. Look at the shading
When the lamp is working normally, the light source is very bright, and children should not be allowed to look at it directly, otherwise there will be glare hazards. And if you want to avoid this situation, you need a certain shading design for the table lamp.
6. Watch the strobe
The use of alternating current lamps and lanterns at home will produce a certain amount of stroboscopy, which can be detected by the strobe is very harmful to the eyes, causing problems such as vision loss and dry eyes.
The eye-protecting table lamp we buy for children needs to ensure that there is no video flash, and the authoritative certification shall prevail. Or make sure that the flickering frequency of the product reaches a high frequency of 3125Hz.
Second, a few good product recommendations
1. Midea's ultra-domain light PLUS
This table lamp has a 470mm long light-emitting surface, which can provide an elliptical illumination area of 1.3m*1.2m, and the light is uniform, which is better than the AA standard. It uses pre-lamp beads to achieve a good spectrum, Ra is 98, R9 is 96, and the blue light level is RG0.
In addition, it has an auxiliary light source above the lamp head, which reduces the contrast between light and dark in the environment and improves comfort.
2, Manshu Rain K1
This table lamp applies violet excitation technology, which reduces blue light directly from the principle layer and achieves a spectrum closer to sunlight. It also uses the red light gain function, which can increase the content of red light above 670nm, which can effectively promote the vitality of the eyes and is more beneficial to children's eye health. The product meets AA standard, high color rendering, Ra>98, R9>92, and applies diffuse reflection and other technologies to effectively reduce glare and shadows.
3. BenQ MindDuo2
The table lamp is also based on violet excitation, and its spectrum is more closely related to natural sunlight. The shading design of this product is very good, and a structural design similar to the eaves is used to effectively reduce the risk of glare. The illuminance is better than AA grade, Ra>95.
4. Babyview OP36
You can take a look at the illuminance and illumination uniformity of HasPro OP36, and the color rendering index of the product is also super high, which is highly recommended.
