Embodiment Construction

[0026] FIG. 2 shows lens 300 including optical imager insert 400 . As an example, the optical imager may be of the same type as in the aforementioned US Patent 5,886,822.

[0027] The ophthalmic display according to the invention comprises an ophthalmic lens 300 comprising an optical imager insert 400 having a polarization direction P for shaping and directing the light beam to the user's eye 1 so that the information content is observed. The display also comprises a polarizing element 2 on one of the faces of the lens 300, preferably on the front face.

[0028] This polarization splitter cube 400 has a high transmittance to P polarized light, which is basically above 90%, has a low transmittance to S polarized light, and has a high reflectivity to S polarized light, which is basically more than 90%. Polarized light has low reflectivity.

[0029] The imager insert 400 is then said to have a P polarization direction, and in this embodiment the polarization direction of the p...

Abstract

The invention relates to an ophthalmic display provided with an ophthalmic lens which comprises an optical image insert (400) provided with a polarisation direction and used for forming optical beams and for guiding said beams towards a user's eye, thereby enabling to visualise an informational content (I). The display also comprises at least one polarisation element placeable on the lens face, wherein said polarisation element is constituted by an adjustable polarisation element (2A, 2B).

Description

technical field [0001] The invention relates to an ophthalmic display consisting of an ophthalmic lens and an optical imager capable of projecting images or information of multimedia type. Background technique [0002] The term "lens" specifically relates to a selection-correction lens adapted to fit in a pair of spectacle frames. Such ophthalmic lenses may exhibit functions such as conventional vision correction, anti-reflection, anti-smudge, anti-scratch. [0003] US Patent No. 5,886,822 discloses an ophthalmic lens with a projection insert. Such projection inserts consist of optical imagers used to shape the beam from an electronic or optical system that generates the beam from an electrical signal from a microscreen, laser diode, or light emitting diode (LED). An optical imager directs a beam of light toward the wearer's eye, allowing the information content therein to be viewed. [0004] Figure 1 is a plan view of such a known ophthalmic display. [0005] An imager ...
