There is no type of 3D glasses that will dagame your eyes, no matter the circumstance you use them in. They may cause eye fatigue perhaps, but that is about it. They won’t dagame your eye sight in anyway.As already stated, the 3D glasses used by a theatre use a technology called “passive” 3D. Its called passive because its simply a filter you have to look through to achieve the 3D effect. The other version, called “active” 3D requires the glasses to separate the image out to establish the left and right eye. These glasses are far more expensive, heavier, and well battery powered. But again, wearing either of these for the “wrong TV” won’t dagame your eye sight in anyway.
