Many parents buy eye protection lamps for their children to protect their eyesight. There is still a lack of conclusive and scientific evidence on whether these lamps have eye protection effects. Therefore, to protect vision, the key is to learn to use the table lamp correctly, instead of blindly relying on the eye protection lamp. Then how to use the table lamp correctly, let's understand together.
Here is the content list:
The power of the bulb should be suitable
The height of the lamp is also vital
The size of the bulb should conform to the lampshade
The placement of table lamps also has a great impact on vision
The power of the bulb should be suitable
First, the power of the bulb should be suitable. If the power is too low and the light on the book is too dark, we can not easily read the handwriting, which will cause visual fatigue and myopia over time, and then the treatment of myopia will become a daily necessity. If the bulb power is too high, the too-strong light will be reflected into our eyes through the white paper surface, causing glare, making the pupils continue to shrink, and causing eye pain and headache. Generally speaking, the brightness of an table lamp between 25 watts and 45 watts is the most appropriate.
The height of the lamp is also vital
Second, the height of the table lamp is also crucial. Generally, when the eyes are 30cm away from the book, they can see the handwriting clearly and will not be too tired. According to this calculation, the height of the table lamp is 40-50cm away from the written text, which not only ensures sufficient reading lighting but also has certain brightness in the surrounding environment.
If the table lamp is too low, it will make the light shine in a too-small range, and the surrounding will be dark. The loss of the reference object for the distant view will make all the adjustment systems of the eyes in a tense compression state of only looking at the close place, which is easy to make the eyes tired and accumulate rapidly, resulting in a "light source myopia". If the table lamp is too high, the light will directly illuminate our eyes, causing glare; At the same time, the intense light at close range will also cause light retention on the retina, which will make the eye muscles tighten and speed up the decline of vision. Therefore, we should also have some knowledge about the treatment of myopia at ordinary times.
The size of the bulb should conform to the lampshade
The third points of how to use the table lamp correctly, is the size of the bulb should conform to the lampshade. We should ensure that the bulb is just covered in the lampshade to avoid immediate light into our eyes.
The placement of table lamps also has a great impact on vision
Finally, the placement of table lamps also has a great impact on vision. Because most people write with their right hand, the table lamp should be placed in the left front of the body. When writing, the shadow will not be formed due to the blocking of the hand on the paper, and the light on the paper will not reflect into our eyes and cause glare, so as not to affect our vision and cause myopia and other problems.
