Prevention of juvenile myopia starts with reading habits

Abstract: students reading and writing for a long time are easy to cause visual fatigue and myopia. Improving reading environment, light brightness and other factors can reduce eye fatigue. We know that correct reading habits can prevent juvenile myopia. So, how to read is the correct reading habit, so as not to be tired? Let’s take a look at…

to prevent juvenile myopia, we need to pay attention to every detail of life. Especially in adolescence, we spend a lot of time reading and studying every day, which is easy to make our eyes tired. How can we read without fatigue? Now I’ll teach you a few moves:

1. Appropriate brightness

light is the most basic condition to cause vision and the factor to be considered in the prevention of myopia. This light is not the glare reflected by the smooth mirror, but the diffuse, uniform reflection emitted by the object, that is, the brightness of the object surface. In order to see clearly, comfortably and persistently, prevent eyesight fatigue and obtain the best visual effect, it is very important to increase the brightness of the object to an appropriate level.


the requirements for the near ambient lighting of teenagers’ learning are:


1. The ratio of the light transmission area of the window to the area of the room shall not be less than 1:6 in the school classroom and homework room under natural light The direction of light input should be from the left, not from the front or right. Prevent reading and writing in direct sunlight. When lighting with artificial light source, the greater the brightness contrast between indoor environment and book pages, the more likely it is to cause visual fatigue. If you only turn on a desk lamp to read in a dark room, your eyes will soon be tired.

therefore, in addition to desk lamp lighting, a small lamp should be turned on indoors to reduce the indoor light and shade difference. The illuminance of the desktop and books is directly proportional to the visual effect. With strong lighting, the vision is improved accordingly, but too strong light is also easy to fatigue.

incandescent lamp compared with fluorescent lamp, incandescent lamp is a warm light source, with soft and stable light and color temperature close to natural light. Learning in this light source environment, eyes are not easy to fatigue.

2. Avoid reading and writing in glare environment. Looking directly at any light source will cause glare damage, so when working in close range, the light source can not directly shine into the eye, let alone read and write in the sun. Reflective blackboard, desktop and white paper can increase reflective glare.

II. Appropriate contrast

brightness, high contrast, clear vision and not easy to fatigue. The books we use and the blackboard in class, if the degree of black-and-white distinction is very low, the brightness and contrast will be reduced. It is difficult to read such words. In order to see clearly, we should move the books closer. The eyes will also use more adjustment, and eye fatigue and myopia will be aggravated. When choosing teaching materials, books and reading materials for students, we should choose varieties with good printing paper quality and printing quality, especially those with color printing and large font, which is conducive to protecting students’ eyes. The blackboard used in school should be kept dark black or dark green without reflection, and avoid direct sunlight on the blackboard, so as to prevent juvenile myopia.
