What kind of light does not hurt the eyes

With the continuous advancement of science and technology, there are more and more types of lamps. As we all know, eyes are more important parts of our body. If there is any abnormality in the eyes, it will have a great impact on people's daily life. Lamps seem to be very ordinary things. Most of the time, although lamps are only used for lighting, they are very important to human eyes. Some lamps can cause great harm to human eyes.

What kind of light does not hurt the eyes?

1. Use white light bulbs. Scientific research has confirmed that our vision is best under white light, so choose incandescent lamps or frosted lamps that emit soft and uniform white light instead of colored bulbs.

2. The degree of the light bulb should be appropriate. If the degree is too low, the light shining on the book will be dim, and it will be difficult for us to see the handwriting clearly. This will cause eyestrain and even lead to myopia over time. If the bulb power is too high, the excessive light will be reflected into our eyes through the white paper, causing glare, causing the pupil to continue to shrink, and then causing eye pain and headaches.

3. The size of the bulb should match the lampshade to ensure that the bulb is exactly covered in the lampshade to avoid direct light into our eyes.

4. The height of the desk lamp is also important. Usually, when the eyes are 30 cm away from the book, you can see the handwriting clearly without excessive fatigue. Based on this, it can be calculated that the height of the desk lamp should be 40-50 cm from the book, which can ensure sufficient reading lighting and a certain brightness in the surrounding environment. If the desk lamp is too low, the light will reach too small an area, and the surrounding area will be completely dark. If the desk lamp is too high, the light will shine directly into our eyes and produce glare; at the same time, strong light at close range will cause light retention on the retina, which will tighten the eye muscles and accelerate vision loss.

5. The placement of the desk lamp also has a great impact on vision. Because most people write with their right hand, the desk lamp should be placed in front of the left side of the body. This way, no shadow will be formed on the paper due to the obstruction of the hand when writing, and the light shining on the paper will not be reflected into our eyes and cause glare.
