What have I done to my eyes so far? ㅠ

Walking while looking at my phoneㅠ Turning off the lights and looking at my phone on the bedㅠ My eyes are dry, but I don't even know artificial tearsㅠ .. What have I done to my eyes so farㅠ

Instead of just complaining about my eyesight getting worse, I should take better care of my eyes. ㅠ
