Do LED Lights Hurt Your Eyes?

The advent of LED lights has provided a lot of convenience for human life. In our daily life, we will come into contact with luminous LED lights.

However, many people believe that the blue light emitted by LED lights will affect the vision of the human eyes. So, will the blue light in LED lights damage the eyes? What's the harm?

Does the blue light in LED lights hurt the eyes?

The tissue used to receive light in the human eye is called the retina. If the brightness of the 400-500nm blue light band in the light source is too high, the eye may cause photochemical damage to the retina after looking directly at the light source for a long time. This damage is mainly divided into two categories: damage caused by blue light directly reacting with visual pigment in visual photoreceptor cells, and damage caused by blue light reacting with lipofuscin in retinal pigment epithelial cells.

When using LED lights, it can be found that the light emitted by the LED lights is blue. If you use it for a long time or directly look at the LED light with your eyes at a close distance, it will be easily affected by blue light and cause damage to the human eyes. Therefore, when using LED lights, you need to pay attention to the correct method. Also, do not often look directly at the LED light with your eyes, to reduce the damage to the eyes caused by the blue light in the LED light.

What is the harm of blue light from LED lights?

LED lights will have a certain impact on the eyes of some people, such as common infants and diabetics. The eyes of these people are most vulnerable to blue light damage. If you are in close contact with the blue light of LED lights for a long time, the probability of retinal damage is relatively high. Because the blue light emitted by the LED lamp has certain radiation, it will affect the retinal pigment epithelial cells.

Therefore, when using LED lights for lighting, you should control the use time. In addition, don't look directly at the LED light with your eyes. When studying under the LED light, you should close your eyes and rest your mind once in a while. In this way, the eyes can be adjusted to prevent the eyes from being affected by the light.

How to effectively protect the eyes?

①Appropriate eye exercises

In life, many adverse factors can cause damage to the eyes, resulting in decreased vision and even eye diseases. Therefore, it is necessary to take reasonable measures to protect the eyes and improve the resistance of the optic nerve. In general, eye exercises can be combined to promote local blood circulation, which is also helpful for the development of a visual function.

② Eat more food that nourishes the optic nerve

During the period of the vision development, it is necessary to eat more foods that can improve vision. This can protect the eyes and improve vision. Therefore, you can usually eat more vegetables and fruits rich in carotene and vitamin A. These nutrients can nourish the optic nerve and improve visual function.

③ The LED lights on the market have better measures to reduce the damage to human eyes. Under normal circumstances, as long as you don't stare at it for a long time, the damage is minimal. If you are still worried, you can think of some small methods by yourself, such as making a beautiful small lampshade by yourself, which is both beautiful and does not have to worry about the damage to the eyes.

It can be seen that the blue light in the LED lamp will indeed cause certain damage to human eyes.

The above is my sharing. I hope it helps you.

Please pay attention to and we will bring you more light source knowledge.
