PRODUCTION OF AN OPHTHALMIC LENS SUITABLE FOR STEREOSCOPIC VISION

摘要

A process for producing an ophthalmic lens which is suitable for stereoscopic vision based on selection of circular light-polarization includes laminating a quarter-wave retarding layer (3) onto an ophthalmic base lens (1). Such process leads to low unit cost for the lenses produced, and a high optical quality. The ophthalmic base lens may be adapted for correcting an ametropia of a wearer of the ophthalmic lens, thereby combining ametropia correction with stereoscopic vision.

1. Process for producing an ophthalmic lens suitable for stereoscopic vision based on selection of circular light-polarization, said process comprising the following steps:
/1/ providing an ophthalmic base lens (1) having an optical surface (S1) of pseudo-spherical shape; /2/ providing a film structure (10), which film structure includes a layer (3) of at least one doubly light-refracting material suitable for said layer to produce a quarter-wave retarding function for at least one wavelength of visible light; and /3/laminating the film structure (10) onto the optical surface (S1) of the base lens (1), so that the film structure conforms to the pseudo-spherical shape.
