Yeah, of course, the cell phone is harmful for our eyes, especially when you are making your eyes staring at your cell phone too much. As we all know that when the cell phone is working, it will release some radiation. When the radiation comes into your eyes, your vision will get weaker and weaker until someday you have to wear the glasses with prescription. Besides, when you focus on the cell phone, you cannot help stopping blink, which result in the lack of water of your eyes, and then you will feel you get dry eyes. Consequently, your eyes are easily ill, such as infection and your eyes maybe get irradiated. Anyway, you had better not make your eyes focus and stare at your cell phone for long time. As a friend, sincerely hope you can keep in mind that too much cell phone do harm for your eyes, otherwise, your eyes will get hurt someday. Good luck.
