My co-workers told me that it is harmful for my eyes' health to work facing a wall (the distance between my eyes and the wall is the width of the desk). I was given a brief explanation but I'm not totally convinced. It involved the fact that my eyes can't look around at a distance since I'm limited to the width of the desk.
My work involves starring at computer screens (reading, coding, etc) almost constantly.
Question: I'm comfortable with working facing a wall. Anyway I do care about my health. So, are there any objective medical/health reasons why working facing a wall might damage my vision?
