A 3-D stereoscopic viewing lens which the retarder "film is made of a PVA film. A 3-D stereoscopic viewing lens having a linear polarized film, one or more lens substrate layers, and an epoxy layer. A process of making retarder film including mounting a PVA film to an assembly line; wetting, cleaning, and washing die PVA film through said assembly line; softening, expanding and stretching the PVA film's x-axis through said assembly line; adding gap filling agent t? the PVA film; stretching the PVA film's y-axis through a width frame holder and as a result transforming the PVA film into a retarder film. |
