Eyes are damaged by persistent use of computer screens. On giving it some thought, it felt quite magical that your eyes are damaged simply by looking at something. I googled where there were articles about blue light and stuff and having felt dissatisfied come to the wiser community here for help.
The question is pretty plain, how does the simple action of looking at a computer screen cause damage to the eye? Is it due to focussing the eye continuously at something close-by?
Is the damage caused to the retina, or the cornea or some other part and in what form? Does the light reshape the lens or something?
Edit: I got glasses of power +1 for both eyes about 3 years ago and 4 years ago, my exposure to computer screens increased to about 6 hours a day. Before that, it was hardly an hour or two a week. The ophthalmologist I consulted also credited it to increased exposure to computer screen.
Hope the questions are clear.
