As parents, our children's health is our primary concern.
But my daughter's recent actions have worried my old father.
Recently, when I was reading a book, my child always rubbed her eyes, and I asked her if there was something in her eyes.
She said that sometimes she can't see clearly, and it can be much better if you rub it.
As soon as I heard this, my mother and I hurriedly took the child to find the eldest child. Husband.
Jingda. The husband examined and found that the child is now pseudomyopia.
If it is not corrected in time, it is very likely that it will be directly myopia.
Because this age is a critical period for the growth and development of various organs.
The same goes for the eyes.
I don't wash my hands and rub my eyes, sit incorrectly, and don't use a desk lamp for reading and writing when studying.
can lead to myopia.
I thought to the child's mother.
Washing hands and sitting posture are usually very strict with children.
It's just that this eye-protecting lamp is really not arranged for children.
I have been using the ordinary table lamp that my cousin's children's house has eliminated.
So we decided to buy a good eye-protecting table lamp for our children.
But I'll go to a certain treasure and search for it.
The variety of table lamps is simply dizzying.
The parameters on the detail page are all very similar. Prices also vary.
It's ridiculously expensive. Cheap and too cheap.
It's hard to start.
So I took advantage of my break after work to do my homework for almost a week.
About how to look at the parameters? How to choose a qualified eye protection table lamp? ……
I will share it with you today for free.
Today I am presenting my achievements in the form of a Q&A (pride).
Q: Which is better, LED lights or OLED lights?
A: OLED is better. Here's why.
We all know that seeing things in natural light is the most comfortable.
Whereas, OLED can directly produce visible light, and the light source is closer to natural light.
Does not contain blue light. It is not harmful to the human eye.
The ordinary LED light source first produces blue light and irradiates the phosphor before producing visible light.
Desk lamps with ordinary LED light sources meet the RG0 standard in order to reduce blue light.
It will increase the blue light filter or filter to reduce the blue light by lowering the color temperature.
Although the LED products on the market claim to be up to standard.
But we really can't tell when we get it.
If the filtration effect is good, it's okay.
But if it doesn't achieve the desired effect, cut corners.
That prolonged use will only be harmful to our eyes.
Q: Are LED table lamps all bad products?
A: Of course not.
It's just that the products of general LED light sources are slightly inferior to those of OLED products.
But compared to the light source generated.
The built-in lamp beads are the most important thing. and even the decisive factor.
As long as the quality of the lamp beads is good, the quality of the entire desk lamp is not much worse than that of LED or OLED.
So someone asked?
How can I judge the quality of the lamp beads, and it is not marked?
We've all heard that you get what you pay for.
I don't believe that a table lamp that is thousands of years old will use the most inferior lamp beads, and some manufacturers will mark the brand of lamp beads.
You can see the picture above, there is a mark, the chip (lamp bead) excited by violet light is used, and the blue light is very low.
Q: There are so many parameters on the detail page, which ones should I focus on?
A: There is a set of eye protection table lamps in the mainland
[GB/T 9473-2022 Performance requirements for desk lamps for reading and writing operations] standard.
This is the latest updated standard version, which has strong authority.
There are a few parameters to look at.
(1) Color rendering:
Generally, Ra should be greater than 80.
For the products of LED light source, Ra should be greater than 0.
Whether it is Ra or R9, it is better to have a data of 95 or more.
(2) Illumination and illumination uniformity: AA grade is preferred.
(3) Color temperature: 4000K is the best. It is useless to adjust the color temperature, and the blue light will increase when the color temperature is turned up.
(4) Blu-ray reaches RG0 standard and no video flash.
Writing this, you basically have a general understanding of the parameters of the eye-protecting table lamp.
Finally, I recommend two good eye-protecting table lamps to everyone.
You can refer to it.
1、欧司朗台灯（XL01）
This table lamp has a full spectrum of natural light.
The color rendering of Ra is greater than or equal to 95, which highly restores the true color.
It is better than the national AA standard.
Authoritative certification no blue light hazards, no flicker.
No light leakage, glare, dark areas.
Prices vary depending on the model.
The price of this one is around 699.
2. Manshuyu K1 eye-protecting table lamp
The illumination and illumination uniformity of the Manshuyu k1 eye protection desk lamp far exceed the national AA standard, and the fifth-generation high-quality eye protection light source is used to achieve a full-spectrum soft light experience. Through multi-dimensional diffuse reflection technology, the product achieves better illumination uniformity and softer lighting.
3. Panasonic eye-protecting table lamp
This table light has a 2.1 illumination uniformity, which makes the light soft and more comfortable.
With diffuser lens technology, there is no ghosting in painting and writing, and the light source is not dazzling.
It is better than the national AA photometric standard. Blue light rating RG0.
Ra97 has high color rendering, which makes objects more beautiful.
Three modes can be freely selected to unlock different light environments. It is suitable for different light consumption needs.
To sum up, these are two fairly good products that I noticed while doing my homework.
The choice is yours.
After seeing so much, the eye-protecting table lamp is really not so easy to choose.
If you are not careful, you may choose a product of poor quality that can cause damage to your child's eyes.
All parents must see more, ask more, and sift more.
Strive to choose the best one for our baby.
