When you choosing lamps for your children, many of you will choose ceiling lamps with cute and interesting appearances.
However, these lamps cannot guarantee the health of their children’s eyesight,
because children’s eyes are still in the process of development,
so lamps used for learning lighting must be paid more attention to.
Whether the light source meets the actual needs of children;
So how to choose an eye-protecting ceiling lamp?
Come with me to learn about 3 important indicators to judge the quality of the light source of the lamp:
1.Blue light hazard level
The harm of blue light to human eyes is mainly manifested in eye pathological harm and human rhythm harm that lead to myopia,
cataracts and macular degeneration.
2.Blue light damages the structure first:
Harmful blue light has extremely high energy and can penetrate the lens directly to the retina,
causing the atrophy or even death of retinal pigment epithelial cells.
The death of light-sensitive cells will lead to reduced or even complete loss of vision, and this damage is irreversible. Blue light can also cause macular degeneration.
The lens in the human eye will absorb part of the blue light and gradually become cloudy to form cataracts, while most of the blue light will penetrate the lens.
Especially in children, the lens is relatively clear and cannot effectively block blue light,
making it more likely to cause macular degeneration and cataracts.
3.Blue light is the second most harmful cause of visual fatigue:
Due to the short wavelength of blue light, the focus point does not fall at the center of the retina,
but a little further forward from the retina.
To see clearly, the eyeballs will be in a state of tension for a long time, causing visual fatigue.
Long-term visual fatigue may lead to symptoms such as deepening of myopia,
double vision, tendency to read serially, and inability to concentrate, etc.,
affecting people’s learning and work efficiency.
4.The third harm caused by blue light is poor sleep:
Blue light inhibits the secretion of melatonin, which is an important hormone that affects sleep.
It is currently known to promote sleep and regulate jet lag.
This can also explain why playing with mobile phones or tablets before going to bed can lead to poor sleep quality and even difficulty falling asleep.
In the digital products used, the level of blue light hazard depends on the chip quality,
as well as the professional handling of various materials and technologies.
According to the blue light hazard level standard, RG0 is a high-quality standard and has no blue light hazard,
so when choosing a ceiling lamp, parents should pay attention to this key point~
2.Strobe depth
Strobe means that the lighting source fluctuates with a certain frequency.
If the strobe lamp is used for a long time, the eyes will be exposed to this environment for a long time,
which can cause headaches and eye fatigue, cause photosensitive epilepsy,
cause vision loss and distraction, etc. question;
Everyone must have encountered that as soon as you turn on the lights at home, the lights will flicker and jump, which is both eye-catching and irritating.
So the second point is to pay attention to choosing a ceiling lamp with a strobe depth of at least less than 0.5%!
3.Color rendering index
“Color rendering index” refers to the ability of a light source to restore the original color of an object. When its value is closer to 100, it means that its color reproduction is higher.
The color rendering index of J&S lighting’s ceiling lamp has been measured as high as 97.8!
The closer the light source of the lamp is to natural light, the higher its color rendering index and the better the light source.
From the perspective of protecting eyesight, lamps with a high color rendering index are the best choice for eye protection lamps that accompany children in their studies!
Master the above 3 points and start preparing a correct eye-protecting ceiling lamp for your child!
4.Which ceiling lamps are eye-protective?
Open all the major platforms, enter the eye protection ceiling lamp, and there will be a lot of them.
Click on it and see that they are all three-tone light. Let me ask you, you already have white light, 5000-6500K, where do you have the courage to talk about eye protection? Doesn’t your conscience hurt?
The so-called eye protection, at least the chip must be full spectrum.
Whether you use a full spectrum excited by purple light or blue light, a full spectrum without sharp blue light icons is good.
The so-called RG0, the so-called no video flicker, and high CRI are all things that are easy to achieve. Don’t use it as a gimmick to deceive consumers.
There is nothing else. You can give me a measured full spectrum chart and then advertise eye protection. This is the most basic requirement.
As a ceiling lamp, I don’t ask you to do side lighting.
In order to pursue luminous flux, you can use direct lighting, just add a lens layer, a light guide plate, and a prism plate.
In my opinion, a living room ceiling lamp with about 120W and a price of more than 1,000 should be enough. But I just clicked on a few big names and saw that the purple light activated exceeded 3,000.
There are more than 2,000 good blue light excitation products. Okay, I admit that I don’t know much about this category, and I have never seriously studied it.
Then I took a look and found that those that cost hundreds of dollars were impossible to see because they all contained high-color-temperature white light.
Unless you buy them and only use yellow light, you will never be able to avoid the harm of blue light.
Therefore, in the entire eye-protecting ceiling lamp industry, the percentage of ceiling lamps that are truly eye-protective is definitely in single digits.
This is a very scary thing. I hope more people will pay attention to this issue, and I hope businesses can change it. Let’s take a step forward and make some products that truly protect our eyes. In fact, this will not have much impact on the merchants themselves.
Face the concept of eye protection squarely, instead of following the crowd and turning a blind eye, knowing that three colors are extremely harmful configurations.
Consumers don’t understand, but I don’t believe that producers don’t understand either. It’s unethical to knowingly and intentionally commit crimes.
Finally, to summarize, currently sold online, regardless of price, Lipro’s ceiling lamps are excited by purple light and can be used with eyes closed.
Berman has a series of violet light excitations with a single color temperature that are available.
Xintali also has single-color temperature full-spectrum ceiling lamps, or three-color ones with a maximum color temperature not exceeding 4500K, which are available.
Philips eyecare series is available. I haven’t found the others yet, I will continue to add them when I see them later.
Dear friends, if you see a product with qualified parameters, you can also leave me a message.
I will confirm it and recommend it to everyone.
I hope everyone can buy a real eye-protecting ceiling lamp and block every hole, no matter how big or small. It brings me a full sense of accomplishment.
