Whether to wear glasses for reading, I believe you must have struggled with this problem if you are short-sighted. Glasses can help myopic people see things far away, reduce eye fatigue, and delay the growth of vision. But for reading and doing homework, do you still need glasses? Whether glasses need to be worn all the time, or only when needed, has been debated.
The myopic children were randomly divided into different groups, some did not wear glasses while reading, and some wore glasses all the time. It was found that the myopia of the children would increase, and the severity of myopia developed faster in children who did not wear glasses than in children who wore glasses.
Therefore, once myopia occurs, whether you wear glasses or not while reading, myopia will deepen. Because of looking at close-up things for a long time, the eye muscles are tense and cannot be relaxed in time, which will aggravate eye fatigue and easily lead to vision loss. Children’s eyesight is still in the development stage, and vision changes are more obvious. However, in adults, after the vision is stabilized, the changes will not be too obvious.
It seems that it would be better to wear glasses for reading, but it should be analyzed according to the specific situation. Whether you wear glasses or not, as long as your eyes feel comfortable. Because the main reason for myopia is that the eye fatigue cannot be relieved in time and the diopter deepens. Therefore, low myopia can be read without glasses; but for medium and high myopia, within a reasonable distance, the handwriting on the book feels blurred, so you have to wear glasses.
Remember that! There is only one standard, and that is to make the eyes feel comfortable. In fact, whether or not to wear glasses for reading is only a second priority. The most important thing is to pay attention to rest. Although reading can enrich the mind and enhance the temperament, you can pick it up and read it at any time. But you only have one pair of eyes to accompany you throughout your life. If you don’t learn how to protect them well, you will regret it in the end but you can’t find the medicine for regretting it.
How should we protect our eyes when we read books?
When studying, the light should be cast from the left side, not from the front or right side. When using artificial light sources for lighting, the greater the brightness contrast between the indoor environment and the book work surface, the more likely it will cause visual fatigue. Therefore, when studying at night, in addition to the desk lamp lighting, a small light should be turned on indoors to reduce the difference between light and shade.
Compared with fluorescent lamps, incandescent lamps are a warm light source with soft and stable light and a color temperature close to natural light. Learning under this light source environment will not easily fatigue the eyes. The best illumination when studying is 200 Lux. For this reason, the incandescent lamp should be at least 40W, and the left light source should be 30 cm away from the table. If 60W is used, it should not exceed 50 cm. Avoid reading and writing in glare environments. Looking directly at any light source will cause glare damage, so don’t read and write in direct sunlight, because the desktop and white paper can increase the reflected glare.
For books used by children, if the paper is not white enough and the ink is not black enough, the contrast will be reduced. It is very difficult to read such words. In order to read clearly, the book must be moved closer, and the eyes need to make more adjustments, which will increase eye fatigue. When choosing teaching materials, books, and children’s books for children, it is necessary to choose the quality of the printed paper and the varieties with good printing quality, especially the products printed in color and with large fonts are beneficial to protect children’s eyes. Do not read for too long, preferably 40 minutes at a time. It is advisable to rest for more than 10 minutes each time. You can look at distant objects and do eye exercises.
