eDimensional 2D Glasses (CIRCULAR 3D VERSION) for use with Passive 3D TVs and in RealD 3D Theaters At least 10% of the population has a bad experience with 3D for one reason or another (such as headaches, nausea or epilepsy to name a few). Now you won't feel left out when everyone else is watching 3D you can enjoy the movie in 2D just as if it was any other normal movie. Works with all home Passive 3D televisions (and with any other application that uses Circular 3D technology) - Works in all RealD Theaters (and in any other 3D theater that uses Circular 3D technology). Prior to now 2D glasses were either to heavy, bulky, horribly overpriced, scratched too easily or just plain low quality throw away style 3D glasses. eDimensional went back to the drawing board to bring you the best value as virtually every manufacturer got it wrong. You may have been to a 3D theater and gotten glasses that were recycled and scratched on the lenses - we decided to double our cost of manufacturing the lenses to make our lenses 2-3 times as thick as theater glasses and we designed them with scratch resistant lenses not to mention we also include a glasses cleaning cloth so there is no guessing on what to use to keep your lenses clean for a longer life. You may have found that your 3D glasses plastic broke after a few uses. We also doubled the cost of our plastic only using virgin top quality plastic that is durable and will bend quite a bit prior to breaking. You may have had 3D glasses that were bulky and too heavy. Our 3D glasses are light as a feather and you will forget that you are wearing them. Don’t mistake the light weight for low quality as you would have to try very hard to break them and with proper use they will last virtually forever. NOT FOR USE IN IMAX 3D THEATERSPLEASE DO NOT BUY THIS ITEM IF YOU ARE PLANNING ON USING THEM IN IMAX 3D THEATERS AS THEY WILL NOT WORKThanks for looking!
