Dear classmates,
I'm sorry to learn that your eyesight is getting weaker these days. I'm Li Hua. I'd like to share with you some ways of protecting eyesight in my daily life.
At school, I often go out of the classroom to play with my classmates or do physical exercise during the breaks. In my free time, I also try hard to avoid using electronic products. You know, the light they give off is harmful to our eyes. Besides, doing eye exercises plays an important role in relaxing my tired eyes. Lastly, I usually have my eyes examined every term to make sure my eyes stay healthy.
I hope you will find my ways helpful.
