Unique lightweight design
The BKM-31G clip-on 3D glasses are extremely lightweight – approx. 16g (0.56oz) – and easy to use, clipping to the lenses of your eyeglasses from the top. In addition, the lenses of these 3D glasses can be flipped up when a 3D effect is not required. The polycarbonate lenses have much less lens distortion than solo-filter 3D glasses and theywithstand temperature changes and shock.
