1. Ideal lighting children reading in too strong or too dim light are not good for their eyes. The ideal lighting should be as follows: (1) table lamp position: when children read and write, the table lamp should be in front of the left desk to avoid blocking the light with their right hand. (2) Table lamp style: it is best to choose a table lamp style that does not directly irradiate children's eyes and is fixed. (3) Lamp brightness: the lamp can use 40 watt bulb or 20 Watt fluorescent lamp to achieve 400-7

1. Ideal lighting

children reading in too strong or too dark light are bad for their eyes. The ideal lighting should be like this:

(1) lamp position: when children read and write, the lamp should be in front of the left desk to avoid blocking the light with their right hand

(2) table lamp style: it is best to choose a table lamp style that does not directly irradiate children's eyes and is fixed

(3) lamp brightness: the lamp can use a 40 watt bulb or a 20 Watt fluorescent lamp to achieve an illumination of 400-700 lux

(4) reduce the light and shade difference: when children study, they should not only turn on the table lamp, but also turn on the lamp in the room, so as to reduce the adverse effect of the light and shade difference on the eyes

(5) orientation and brightness of chandeliers: most of the lamps in our general living rooms are suspended from the ceiling. The lighting required for daily life can be 40 Watt fluorescent lamps or 60 watt bulbs. If there is enough light in the left front of the desk, it is OK not to use a desk lamp

(6) the bulb should be updated in time: the table lamp and the lamp in the room should be kept clean frequently. When the bulb is used for too long, or when it flashes or the lighting decreases, it must be replaced in time to ensure sufficient illumination

2. Children should not use fluorescent lamps when reading.

the latest research data shows that fluorescent lamps are easy to cause myopia in children, while incandescent lamps can avoid this problem. A scientific research institution in Guangdong Province found that 15.12% of the students whose eyesight decreased after half a year in classes illuminated by fluorescent lamps; In the classes with incandescent lighting, the vision loss was only 4.6%. Then, after three months of switching between the two groups of lighting fixtures, the results showed that the elderly accounted for 1.07% of the total in the classes that switched to incandescent lighting

why does fluorescent lighting have adverse effects on students' vision? This is because the cold fluorescent light produced by the fluorescent lamp has a gray blue tone. Under this light, the text patterns on the books lack a clear outline, which is easy to cause the reader's eye fatigue, and over time, induce myopia or deepen the degree of myopia. Therefore, experts suggest that incandescent lamps are better for school lighting

3. Teach children not to read in strong light

when children read and write, if the light is dim, they can often be persuaded by their parents, while reading and writing in strong light is often ignored by their parents. In fact, strong light is also harmful to eyes. Because sunlight contains ultraviolet and infrared rays, if you often read in strong light, your eyes will be stimulated too much by ultraviolet rays, and the conjunctiva (white eyes) and cornea (black eyes) in front of your eyeball will be damaged, causing problems such as eye tingling, tears, fear of light, difficulty opening your eyes, etc. The penetrating power of infrared ray is stronger than ultraviolet ray. If the eyes are stimulated by infrared ray too much, the retina inside the eyeball will be injured

therefore, parents should pay attention to the harm of strong light to children's eyesight, and should timely advise children not to read and write in too strong light, so as to avoid ultraviolet and infrared rays in the sunlight reflecting from books to their eyes and damaging their children's eyes
