Question

I'm trying to figure out how to modify my working conditions so that I can program longer without harming my eyes. Because doing so experimentally hasn't given conclusive results so far, I decided to ask for studies in this area.

Does looking at a bright screen in a well lit room strain eyes more than looking at dark screen in a dark room for prolonged periods of time? Or is there a middle ground somewhere in-between that is most harmless? Or is it a combination of contrasting screen/background?

I'm not asking for medical advice here. I already went to several doctors and they gave me different, sometimes contradicting answers, so I'm just looking for research.

Explanation / Answer

I think the principle is "everything in moderation". Environment should be not very bright and not very dimmed. Also, the contrast should be moderate too, i.e. having bright screen in dark room is not good. Also, he type of work should not be very constant, i.e. you should sometimes change looking at the screen to looking in the window and similar.

Remember, that the light is required for stimulating the brain activity.
