myopia is a serious problem in today's society, and it has even been regarded as a trend.

With the increase of grade, the number of nearsighted students in our class has gradually increased, which has far exceeded half.

after investigation, I found that most students in my class have the most eyesight of 4.8 and 4.9, and only a few students have kept their eyesight above 5.. There are 11 students with glasses, but 2 are nearsighted, and there are only 31 students in our class! There are only 11 people without myopia!

through Baidu. com, I found that myopia can be divided into three types. The first type is axial myopia, which is caused by the excessive development of the anterior and posterior axes of the eyeball. The second is caused by excessive bending. The third kind is refractive myopia, which is caused by high refractive index interstitial rate.

In view of these survey data, I would like to give you a suggestion:

Do a good job in writing and reading, and don't lie prone on the desk or twist your body. Books keep a proper distance from our eyes. Reading and writing time should not be too long, keep proper rest and play less computer. The light should be appropriate when reading and writing. Vitamin B is good for the eyes. Myopic students should eat more foods containing more zinc. Do eye exercises seriously.

Let's promote eye protection and make the world brighter in everyone's eyes!
