Sweetie, you just need to keep a healthy diet then you can supplement enough nutrients for your eyes. Fruits that are rich in vitamins are also good for our eyes. You can eat some fruits daily. With the development of our society and technology, there are many things that can impair our vision. So I think we should be careful in our daily lives. I used to read books or play games on my phone before going to sleep. After I turn off my phone, I can't see things clearly in the dark for a long time. Later I found that my eyesight decrease dramatically. I guess it must be caused by phone. So I stop reading books on phone or playing games before going to bed.
