Yes health is the most important thing in life. Mostly in this technological generation. There was a time I was also thinking of it the way you said. But mine was not eye. Health is the first priority in all human on Earth. Eye problem is one of the worst sickness in the world though no sickness is good. So please you have to take care of the high very well, there are sometimes when I look or operate laptop or mobile phone for a long period of time, my eyes would be paining me very seriously and at that time I could not operate it again, so what I normally do is that I used eye drop and yeast tablets for morning, afternoon and evening. And it works for me very well. So if I will suggest for you take yeast and eye drop then stay on screen for not more than 2 or 3 hours. It is better you stay alive to enjoy your labor.
