How To Use A Desk Lamp

Many parents buy eye protection lamps for their children in order to protect their eyesight, but in fact, there is still a lack of conclusive and scientific evidence on whether these lamps have eye protection effects. So, to protect your eyesight, the key is to learn how to use a desk lamp correctly, rather than relying solely on eye protection lamps. How to use a desk lamp correctly? Let's learn together:
Firstly, the degree of the light bulb should be appropriate. If the degree is too low and the light shining on the book is dim, it is difficult for us to see the handwriting clearly, which can cause visual fatigue. Over time, it can also lead to myopia. Treating myopia has become a daily necessity. If the degree of the light bulb is too high, the excessive light will be reflected into our eyes through the white paper surface, causing glare and continuously shrinking the pupils, leading to eye pain and headache. Generally speaking, incandescent lamps with a brightness of 25-45 watts are the most suitable.
Secondly, the height of the desk lamp is also important. Usually, when the distance between the eyes and the book is 30 centimeters, the handwriting can be seen clearly without excessive fatigue. Therefore, it can be inferred that a height of 40-50 centimeters from the writing is more suitable for a desk lamp, which ensures sufficient reading lighting and a certain brightness in the surrounding environment.
If the desk lamp is too low, it will cause the light to reach too small a range, and the surroundings will be pitch black. Losing a reference point for distant vision can cause the various regulatory systems of the eye to be in a tense and compressed state of only looking up close, which can easily lead to eye fatigue and rapid accumulation, resulting in "light source myopia". If the desk lamp is too high, the light will directly shine on our eyes, causing glare; At the same time, close range strong light can also cause light retention on the retina, causing eye muscle contraction and accelerating vision loss. Therefore, it is important to have a good understanding of the treatment of myopia in daily life.
Thirdly, the size of the light bulb should match the lampshade, ensuring that the bulb is perfectly placed inside the lampshade and avoiding direct sunlight to our eyes.
Fourth, use a white light bulb. Scientific research has confirmed that our vision is best under white light, so choose incandescent or frosted lamps that can emit soft and uniform white light, rather than colored light bulbs.
Finally, the placement of the desk lamp also has a significant 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. When writing, it will not create shadows on the paper due to the obstruction of the hand, and the light shining 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.
