Environment was a well-lit Best Buy
- Immediately upon the active glasses activating (usually when they've been synced to the monitor for programming material), the back of my eyes itch slightly.
- Five minutes in, and my brain feels fuzzy, while my eyes physically hurt (level 1/10 - annoyance, yet noticeable)
- Ten minutes in, I have a headache that's a 3/10 on the pain scale (enough to pop pills, if only because I know it'll get worse if I don't do so soon.) My eyes also hurt physically (4/10), and I find myself rubbing them on a regular basis to try and alleviate symptoms.
- ~13 minutes in, and nausea has set in. Headache is now a 4.5/10, while my eyes literally refuse to focus on the display (pain is 5/10). I promptly removed the glasses and had to rest for a few moments until symptoms dissipated.
, the program material was bright and colorful in nature, and the display center was eye-level with the glasses. Viewing position was 0 degrees center. The longest test was done on a Samsung (1st gen), though symptoms present themselves in the same fashion and times with newer displays from Samsung, Panasonic, Sony, etc. It's a shame, because LG's passive lenses look great, but the loss of vertical resolution at large screen sizes is a deal-breaker for me (on the 3DS' smaller screens, it's a non-issue). If LG unveils a sub-$5k panel that does full resolution 1080p in 3D using passive glasses, I'll be a Day One adopter, credit card be damned. I know they claim I can see the entire detail based on how the eye works, but I still see scan lines on their 3D
"in a well lit Best Buy” so you were surrounded by many florescent light fixtures flashing a 60Hz and put glasses in front of you eyes that are flashing back and fourth at 120hz synced to a screen flashing at 120Hz (the lights are not synced to the TV) and you wonder why you get eye strain. That's why the passive looked so much better because polarized light from the TV is not bothered by the outside light source. Please try your experiment in an environment without outside light (especially florescent). Unfortunately they are hard to come by as places like BB don't have properly lite display rooms and definitely give a bad rep to active displays.
