Homework is an essential part of a child's academic life. And if your child's eyes are uncomfortable while doing their homework, then be careful! It is likely that there is a problem with the child's desk lamp, or it is not used properly, and if the matter is not addressed in time, it is likely to cause the child's vision to deteriorate.
So, how should a table lamp be used correctly? And how to choose the right one?
First, the use of table lamps
1. Don't turn off the indoor headlights
If only the lamp is left on in the whole room, then there will be a particularly noticeable chiaroscuro.
The human pupil is very sensitive to light, constricting when the light is too bright and dilating when it is too dark. When children do their homework in an environment with obvious contrast between light and dark, their pupils dilate frequently, which can lead to problems such as eye strain.
2. Rationality
First of all, the height of the table lamp must be appropriate, generally about 40-50cm. If the lamp is too high, then its shading design will lose its effect, causing the light to enter the child's eyes directly, causing glare problems; If the lamp is too low, it will cause the lighting area to be too small, forming a strong contrast between the light in the middle and the darkness around the periphery, which will bring a heavy burden to the child's pupils.
Secondly, the position of the table lamp is also particular. Since most of us write with our right hand, placing the lamp in front of the left can effectively prevent shadows from blocking the view, and if we are left-handed, put it in front of the right.
3. Pay attention to reflective problems
Do not put reflective objects on your child's desk, especially metalwork and small mirrors, as this can cause reflected glare.
In addition, the lamp should not be turned too bright, otherwise it will reflect the light on the book. When a whitening area can be seen in a child's book, it means that the reflection is already very serious.
4. Pay attention to usage habits
Don't let your child study under the lamp for a long time, the young should get up and walk every 20 minutes, and after school, you can get up and walk every 45 minutes according to the class habits, which can effectively reduce eye strain.
5. Choose a suitable table lamp
If the lamp itself is problematic with the child using, then no matter how much attention is paid to how to use it, it will be useless.
For example, uneven light distribution, obvious strobe, excessive blue light and other problems will directly harm children's eyes; Then there are the design problems of the lamp, such as the direct exposure of the light source and the reflection of the base of the table lamp, which are also very hurtful to the eyes.
Therefore, the table lamp for children must be well chosen.
Second, the purchase of table lamps
1. Photometric grade
The illumination and uniformity of the product should meet the requirements of the national standard AA luminosity level, so that it is bright enough and there will be no uneven brightness and darkness.
2. Color rendering
Using a table lamp with a high enough color rendering can ensure that the items on the table will not have color deviations.
For products for children, try to achieve a color rendering of Ra and R9 greater than 90.
3. Color temperature
The color temperature of the table lamp used by children at night should not exceed 4000K.
4. Shading
In order to prevent the light source from directly irritating the child's eyes, the table lamp must have a proper shading design.
5. Strobe
Products need to be certified as non-stroboscopic hazards.
6. Blue light
The blue light level of the table lamp must be RG0, and RG0 is the safest level.
3. A few good product recommendations
