"Bogus" probably came across as more dismissive than I meant - apologies if that caused offence - what I was referring to is the argument some people make that eye strain is caused by light being shone into your eyes by the backlight, and that in some way light reaching your eyes via reflection is different and more benign. Direct light bad, reflected light good.
Reflection can indeed change the nature of the light (e.g. it can be polarized to a greater or lesser extent depending on how near the angle of incidence is to the Brewster angle), but the eye can't detect polarization so it seems unlikely this could cause a problem.
I do believe that at least the vast majority of eye strain issues with backlit LCDs is down to inappropriate brightness.
