How to use the Table Lamp

The key to protecting eyesight is to learn to use table lamps correctly, rather than blindly relying on eye protection lamps.Then how to use the table lamp correctly:

First, the degree of the bulb should be appropriate. If the degree is too low and the light on the book is dim, it will be difficult for us to read the handwriting clearly, which will cause visual fatigue, and will lead to myopia over time. If the light bulb is too high, too strong light will be reflected into our eyes through the white paper surface, causing glare, making the pupils continue to shrink, causing eye pain and headaches. Generally speaking, the brightness of 25-45 watt incandescent lamps is the most suitable.

Second, the height of the lamp is also important. Usually, when the eyes are 30 cm away from the book, the handwriting can be clearly seen without being overly tired. Based on this calculation, the height of the table lamp is 40-50 cm away from the writing. This will not only ensure sufficient reading lighting, but also the surrounding environment. brightness.

Third, the size of the bulb should match the lampshade, and it should be ensured that the bulb is just covered in the lampshade to avoid direct light from our eyes.

Fourth, use white light bulbs. Scientific research has confirmed that our eyesight is best in white light, so choose incandescent or frosted lamps that emit a soft, uniform white light instead of colored bulbs.
