Myopia (nearsightedness) is becoming a major problem in today's world. Many "professionals" will say its all genetic and there is nothing you can do. This is a blatant lie, the eyesight problems of humans in modern civilization is entirely from misuse of our eyes. Our ancestors didn't spend hours upon hours looking at screens close to their face. There have been studies done about eskimos regarding eyesight. The parents that lived a natural life, virtually none of them had eyesight problems. But whne schools were introduced for the kids myopia rates started to skyrocket...
I can definitely see how the progression from using computers, from desktop, to laptop, to tablet and now our phones (most of which are powerful computers as well) has created a shift with an increasing number of people requiring corrective lenses due to 'acquired', rather than 'inherited' myopia. Likely, if practiced regularly it can only be good to take more breaks and intentionally focus away, so on longer distances and if not just across the room -- take a walk and enjoy the landscape and surroundings outside for a bit and focus on something across the street.
Myopa is often called nearsightedness, people can not see clearly writing, car plates, television, movies, long-distance traffic signs. For myopa patients will look blurry, for students who suffer from nearsightedness should use sunglasses according to size as a tool of vision and sitting in front of the class.
Well the exception is the mention of
writing in your first sentence. With nearsightedness, or myopia, one can see good up close as in for reading and writing, including doing work on the computer and your cell phone; all of which are the opposite for the farsighted person who will need corrective lenses for doing these tasks.
