Your're probably still rejecting the fact that 3D's back on Netflix.
Seriously, the resolution is different from the PS3 and it is 720 x 1280 as opposed to the Blu Ray 3D which is 1080 x 1920 so the image should be less fuzzy on the Blu Ray. However, the motion on the PS3 is higher frame rate being 60p vs. the Blu Ray which is 24p. Now here's the rub- The 24p from Blu Ray is not an interpolated 24 frames per second but actually the same as the source was shot ( except in a few productions). On the PS3 the 60 P frames per second is upconverted from the original 24 frames which is extrapolated, i.e. not real. Ordinarily I would think a slower frame rate would be more bothersome but in this case the extrapolated converted frame rate may be
what's bothering you.
But, if I had to place a bet on it, I would bet it's the lower resolution conversion making the image softer which in turn has your brain trying to focus the image , working your eyes harder. When you are trying to focus on soft images constantly that is indeed what can cause eye strain. I have often felt that when people get headaches watching good quality 3D, they really should get an eye exam and maybe need corrective lenses. I also notice that people wearing progressive glasses will suffer more with 3D eye strain too. My wife needs corrective glasses but can't wear her Progressives for 3D. Instead we worked with the optician and made a set of custom 3D active shutter glasses with her Rx for the seating to screen distance. Her 3D stereo vision is perfect now and never gets eye fatigue.
