Contrast is only listed at 750:1 compared to my beloved bulky 2x 3DTV Corps from Amazon which are 1200:1 contrast. But these cheap ones will be for an occasional guest (unless they completely suck). Some have said that certain glasses block red flash better than others - while I've also heard that they either block red flash or they don't and that there's no middle ground. Could be that these will not appear to do such a great job at it anyway since there are no sides to block the red light in your peripheral vision
I'll report back and let you guys know if they are halfway decent or not. From the design it looks like they just bought a bunch of discontinued Samsung glasses and repurposed them
Ok so as promised here's my review of these super cheap 144hz glasses. As stated above they cost me $11.85 shipped (now listed at $12.96 at link above. Note:low stock) I'm going to make this a comparison as I compared all three types of 144hz 3D glasses I have on hand.144Hz 3D DLP-Link Active Glasses for BenQ/Optoma/Acer/Viewsonic/ LG/ Projector $12.98 (pictured above, use 2025 battery)
So for the price and quality, these get a big thumbs up! The lenses are smaller than I like, but these are cheap and the performance is excellent so they are perfect for guests (and larger gatherings). Give these to your kids/nieces/nephews and save the more premium/comfortable glasses for the more discerning guests. Not that you will notice much of a difference between these and higher priced glasses as performance with the other two glasses listed below was pretty much equal across the mapBlock Red Flash: Good/Acceptable.
There's nothing to block the light out of your peripheral so that may factor in. But there was no difference in the amount of red on screen compared to the other two glassesComfort: Okay.
Super Lightweight. But not the most comfortable. *WOULD NOT recommend to prescription glass wearers as they slide around a LOT compared to similar lightweight glasses. No rubber nose piece. The arms don't fold so they are a bit stiff (detachable), but once they are on your face they are plenty comfortable as long as you don't wear prescription glassesPerformance: Crystal Clear 3D NO PROBLEMS
*Except perhaps field of vision as the lenses are SMALL. Uses the smaller 2025 replaceable batteriesSainsonic Rainbow (Rechargeable) $22.99
For around $20 these are decent. I believe when I bought these they were listed as 3Dtv Corps glasses as well. A lot of these 3D glasses are made in China at the same factory and rebranded for various companies. The fact that they are rechargeable is nice IF you prefer that, but when they are dead and the movie is about to begin you might wish they had a replaceable battery and you didn't ever have to worry about babysitting/charging your glasses beforehandBlock Red Flash: Good
Again these won't block light from your peripheral either, but the frame is bigger and the curve of the glasses helps compared to those listed above so they are a notch betterComfort: Good
Lightweight. Rubber nose piece. They don't slide around if you wear prescription glasses. I WOULD recommend these to those who want a cheap AND comfortable rechargeable pair of 3D glassesPerformance: These glasses had some issues with ghosting
UNTIL I pressed the button and it switched the left/right eye back to the proper alignment. They give you the option to switch views/eyes which is nice I guess, but I don't like the fact that if one of your guests switches eyes and then later turns these glasses off....the next time you turn them on you will need to press the button and switch back or you WILL notice ghosting. The other two pairs of glasses did not ghost as badly when left/right eye views were switched, so THAT function of these glasses maybe not work properly. But used properly there is no ghosting and these are decent for the price and comforable3DTV Corp (Bulky 2032 Battery Powered) $58 for 2 pair - basically $29 each
They cost a bit more, but they are worth it in my opinion. They're a bit bulky and an older model of 144hz 3D glasses. But one super nice extra about that is that if you wear glasses like me and have an old pair of prescription glasses - those lenses will likely fit and can be nicely taped inside if you want to use a small bit of scotch tape at top/bottom so that you don't have to wear two pairs of glasses. It looks nice how I did it, and noone else can tell. I've noticed both pairs of these I have, have a tendency to occasionally kill even a brand new battery from time to time for some odd reasonBlock Red Flash: Good/Great
These bulkier frames don't let in hardly any light from the sides, so that's a bigger plus, and there is no noticeable extra redness on screen when compared to the other glasses.Comfort: Good
Not as light, and definitely bulkier, these may take some getting used to. My wife didn't like them at all at first, but now prefers them so give it timePerformance: So-So/Good when viewed straight on
But at ANY ANGLE you will have issues. If you turn your head to the left the colors get noticeably warmer/redder and if you turn your head to the right the colors wash out and get cooler/bluer. But when viewed straight on everything is as it should be as. Watching Cars 1 in 3D, I will mention that colors may have been a tad bit duller with these compared to the other two glasses, but the difference was almost negligible. The other glasses perform slightly better IMO AND perform well even when you turn your head from side to side or sit at a more extreme viewing angle to the screen - so though I loved these glasses before, I believe I will look into 3DTV Corps 4th and 5th generation glasses (and other brands) as this may not be an issue with the newer glasses
One quick note on blocking red flash: It is an artifact of the DLP 3D technology, but IMO not an issue to do with the glasses so much. I believe that ambient light and especially any red reflections coming off the screen and reflecting off your walls/ceiling play a bigger role in a dark room as some of that enters your peripheral vision especially with glasses with no sides on the frames. It is not an issue at all in my setup, and others have said the same. But some people may be more sensitive, or have excessive reflections from the screen in their setup. And another thought on that - I believe the contrast of the glasses directly relates. You definitely want a higher native contrast to whichever glasses you pick out, which will make blacks blacker. Poor contrast in *some* of the cheaper glasses result in blacks not looking as black, and therefore looking lighter - or redder in the case of this technology
The only expert opinions I've read on the measurable difference in contrast with these type of 3D glasses is that it does matter to an extent. BUT as those with projectors know the lighting conditions/reflections in your room matter much more when it comes to contrast. You can have the highest contrast with your 3D glasses, but if you're watching with a lot of light in the room contrast will be poor and blacks will look much lighter/redder. Even with the cheap $12 ones I reviewed above, whose contrast IS LESS than the bulky 3DTV ones, blacks were JUST AS GOOD and appeared just as dark on screen in my completely dark roomEdited by gamermwm - 2/6/14 at 3:07am
