...Probably a habit from an old science instructor who used to yell at us and call us idiots for closing one eye to look through a microscope.
As a former amateur astronomer I developed a habit to keep both eyes open because having one eye shut you seriously loose in visual acuity of the open eye. The expuanation, if I get it right, is that our brain, being accustomed to recognise things in stereo vision, looses some vital information about the relative position and dimensions of objects in case if it's received in mono. For this reason the stereo vision seriously strengthens visual brightness of objects and eye's resolving power (the things seen in stereo look brighter and sharper) what is crucial in observation astronomy. I read somewhere that stereo vision boosts visual brightness up 20 percent. I don't think it's that important in photography. It also can add to the explanation of why viewfinders are now nearly eliminated from consumer-market products.
