Xiaobian support: how to choose the table lamp that does not hurt the eye
1. With white light bulbs, scientific research has confirmed that our vision is best under white light. Therefore, choose incandescent or frosted lamps that emit soft and uniform white light instead of colored light bulbs.
2. The degree of the bulb should be appropriate. If the degree is too low, the light on the book is dark, we can not easily see the writing, which will cause visual fatigue, and long time will lead to myopia. If the bulb is too high, too much light will be reflected through the white paper into our eyes, causing glare, which will continue to shrink the pupil, causing eye pain and headache.
3, the size of the bulb should match the lampshade, to ensure that the bulb is just inside the lampshade, to avoid direct light to our eyes.
4. The height of the desk lamp is also very important. Usually, when the eyes are 30 cm away from the book, they can not only see the writing, but also not excessive fatigue. From this calculation, the height of the desk lamp is more suitable for writing 40-50 cm, so as to ensure sufficient reading illumination and the surrounding environment is also certain. Brightness. If the desk lamp is too low, it will cause the light to be too small and the surroundings will be dark. If the desk lamp is too high, the light will directly shine into our eyes and produce glare. At the same time, close-range glare will cause light retention on the retina, which will make the eye muscles tighten and speed up vision loss.
5. The placement of the desk lamp also has a great influence on vision. Because most people write with their right hand, the desk lamp should be placed on the left front of the body. When writing, it will not form a shadow on the paper because of the cover of the hand. The light shining on the paper will not reflect into our eyes and cause glare. .
