Most modern lenses are made from plastics, especially acrylic, polystyrene and polycarbonate. Plastics are lighter and tend to transmit more light than glass. Furthermore, optical corrections are more easily accomplished using various plastic elements. Handled with care, these devices have an indefinity life; minor scratches can be removed by polishing the lens with Kimwipes and a tiny amount of fine grade diamond compound (which is not as expensive as it sounds!).

Linear polarised 3D glasses aviation-style

LINEAR POLARISED 3D GLASSES

aviation style

These linear polarised lenses are of superior quality, mounted in aviation-style, black plastic frames, with hinged arms. Lenses are 0.254mm of polariser film. Polarised glasses contain light Gray filters for viewing slide shows, multi-media displays, concerts, movies, and ride simulators. Linear polarised filters are cut at opposing 45-degree angles, which unless otherwise requested are at 45 + 135°; e.g. if the right image is blackened by double polarisation, then after turning the glasses anticlockwise by 90°, the left image is blackened. Polarising sunglasses have both lenses mounted identically and they have a weaker polarising effect. Special orientations can be obtained but an order for several hundred is required.

How to determine if a polarising filter is circular or linear

Hold a polarising filter in front of your eyes, facing the light. Now hold another polariser in front of it and rotate it slowly.
If it is a circular polariser, the rotation will cause the filter to black out on one side only, and not at all if the polariser is turned over.
If it is a linear polariser, it will black out when rotated to 90 degrees whether front on or back to front.
