As a father who has been suffering from myopia for many years, I naturally don't want my children to be like me.
I know how good outdoor activities are for your eyes. Bright natural light, like a gift from nature, can delay the growth of the eye axis, reserve valuable "long-term vision" for children's vision, and try to prevent children from myopia. However, the reality is that as children grow up, they spend more time indoors with books and electronic products.
I originally thought that as long as we control the time children watch TV, use electronic products, and increase the frequency of outdoor use, we can reserve enough long-term vision reserves for children. But as the child's homework increased and the time he spent using his eyes increased, he always complained to me that his eyes were uncomfortable and felt "sore and swollen."
At first I thought it would be like this after studying for a long time, until one day I accidentally saw that when my child was preparing to do homework at night, he would squint his eyes as soon as he turned on the desk lamp. Although he got over it after a while, he would always rub his eyes from time to time. Eye. I realized that the direct light suddenly brightened after turning on the light, and reading under the dazzling direct light for a long time, the damage to the eyes was not comparable to the "long-term vision" I had reserved for him.
For this reason, I began to look up information and consult doctors, hoping to find a better solution. I found that protecting eyesight does not just mean increasing outdoor sports. That is unrealistic. After all, children still spend most of their time indoors. So, how to create an environment for children indoors that is both suitable for learning and protects their eyesight?
The answer is diffuse lighting. I have found that children's eye fatigue can be effectively reduced by avoiding direct indoor lights and choosing soft, even light sources. It is like holding up a protective umbrella for the child's eyes, allowing him to protect the child's farsightedness reserve while learning.
After doing a lot of homework, I promptly started to learn about buying eye protection lamps, hoping to reduce the pressure on my children's eyes. The reason why I say "not in time" is that I don't have much knowledge about lighting eye protection, which delays the child's farsightedness reserve. Therefore, I decided to write an article to tell you in detail the differences between lighting and lighting, especially the importance of the way lamps emit light.
In the process of purchasing eye protection lamps, I learned that different lighting methods of lamps have different effects on children's vision. Among them, the most common lighting methods are direct light and diffuse reflected light, while diffuse reflected light Compared with direct light, it is more eye-friendly and can reduce the probability of myopia in children.
·Compared with direct light, why diffuse reflection is more eye-friendly?
Direct light, as the name suggests, means that light is emitted directly from a point or a line, without being scattered by any medium, and directly illuminates the target object. This lighting method often produces strong lighting effects and obvious contrast between light and dark, but it can also easily cause a series of visual problems.
For example, when exposed to direct light for a long time, people often feel eye fatigue, dryness, and even discomfort symptoms such as headaches and dizziness. This is because the strong stimulation of direct light will cause the pupils of the eyes to shrink continuously, and the ciliary muscles will be in a state of tension for a long time and cannot get effective rest.
Therefore, when children are reading, they often sit where they sit. When the light is turned on, a shadow first appears, showing a particularly strong contrast between light and dark.
In contrast, the diffuse light of indirect lighting can reflect light evenly into the space through surfaces such as ceilings or walls, forming a soft and uniform lighting environment. This lighting method does not produce strong contrast between light and dark, nor does it Can cause dazzling glare.
On the contrary, it can provide uniform illumination, making the light distribution of the entire space more even, reducing the generation of shadows and glare. With the same brightness, the lighting effect of diffuse light will be much friendlier to the eyes.
To use an analogy, if the direct light is a particularly dazzling spotlight on the stage, the diffuse light is more like the light emitted by the morning sun, which is soft, natural and not dazzling.
Can diffuse light really reduce visual fatigue?
Compared with direct light, diffuse light can not only provide uniform illumination, but also make the glare softer and reduce the contrast between light and dark. The light source it provides is gentle and comfortable, and will not irritate children's fragile eyes.
First of all, the uniform illumination of diffuse reflector lamps can avoid local over-brightness or over-darkness, and any position in the room can receive sufficient illumination. The key is that under the illumination of diffuse reflector lights, the intensity of light is coordinated and consistent with the surrounding environment. Not only is it more visually comfortable, but the visual experience is also more like natural light;
Secondly, diffuse reflection light can also effectively reduce glare, which means it is less irritating to the eyes. Even if you read under the light for a long time, it will not put too much burden on the eyes. Because it is the light after the light has been scattered, it is similar to the light from the sun shining on the lake surface and being reflected by the lake water to the ground. After refraction, the stimulation of the light source is reduced and it is no longer dazzling. The most intuitive feeling is that even if you lie in bed and read a book, or stare at the lamp and write for a long time, you will not feel dazzled or tired. The discomfort of sore eyes and constant blinking has almost completely disappeared.
Because this "scattering" method can well reduce the risk of eye fatigue and dryness, and protect vision.
Also, diffuse light has lower contrast. If under direct light, the reflection and high contrast on the surface of the object may cause visual illusions or distortions, while diffuse light can reduce the reflection on the surface of the object by scattering the light, thereby reducing the contrast. This eliminates the need for the eyeballs to frequently adjust the focus and pupil size when observing objects, greatly reducing the burden on the eyes.
In general, diffuse reflection lamps still have very natural advantages in eye protection. They can not only provide uniform illumination, but also reduce glare and reduce the contrast between light and dark, thereby reducing light irritation to the eyes and preventing visual fatigue. However, when purchasing diffuse reflection lamps, you still need to pay special attention to the luminous flux of the diffuse reflection lamps, which is what we often call "whether it is bright enough." Some merchants will greatly reduce the luminous flux of the lamps for the sake of softness, so that the illumination , the brightness simply cannot meet the lighting standards for children to learn to read.
