What are the requirements for lighting when reading and writing?

In daily life, when we read and write, our eyesight will be unconsciously affected by the lighting of the environment. As learning tasks increase, the age of myopia in children continues to advance, and it is particularly important to maintain a good lighting environment. So, what kind of lighting environment can protect children's eyes to the greatest extent while concentrating on learning? Today, the CDC will conduct a specific analysis for you in terms of different learning environments:

. When studying in the classroom

When students are studying during the day or in good weather, it is most comfortable for students to read and write in natural lighting, but remember to avoid direct sunlight.

You can turn on the eye protection light in the evening or when the lighting is poor. The more common eye protection lamps usually adopt the principle of high flickering. When the flashing frequency of the light exceeds the speed of the human eye's nerve reaction, students will not feel the strong flicker of the light and become tired of the visual object. At the same time, turning on the eye protection lamp can help us learn in an overly dark environment, avoiding the eyes from using more adjustment abilities due to inability to see clearly, which leads to the eyes being in a state of constant tension and causing visual fatigue.

. When studying at home

When students go home, they usually read books and do homework at night. At this time, everyone was accustomed to turning on the small desk lamp on their desks. It is not advisable that the desk lamp is too dark or too bright. Select LED desk lamp with a bulb of 40 to 60 watts (center illuminance is 500 to 750 lux, brightness is 120 to 150 candela/square meter).

You can turn on the ceiling light before turning on the desk lamp to reduce eye fatigue and discomfort caused by excessive brightness between the desk and the environment. The desk lamp should be placed about 30 cm opposite the hand of the writing, at about 45° angle to the tabletop, and keep the distance from the book between 60 and 70 cm.

Screen brightness needs to be adjusted?

When taking online classes in different time periods, the brightness of the environment will change significantly. So is it necessary to adjust the brightness of the screen at the same time to make the hard-working eyes more comfortable?

. Day

When the daylight is good, the brightness of the screen can be adjusted to 40%~60%, and the contrast can be adjusted to 60%~80%. This can not only ensure that students can see the screen clearly, but also avoid discomfort caused by excessive brightness.

. nightnight

At night, since the screen itself already has background light, it will form a strong contrast with the dim environment. At this time, it is recommended that students turn on the room light and adjust the brightness of the electronic screen to a level that makes them more comfortable (not so dazzling or glaring) according to the brightness of the room light.
