Techniques and assemblies for steering light rays are described. An electro-optic prism is operable to provide controllable steering of solar rays. The electro-optic prism includes a first electrode, a reference electrode and an electro-optic material positioned between the first and reference electrodes. In one implementation, the first electrode includes multiple substantially parallel linear electrodes positioned on a first substrate and the reference electrode is positioned on a second substrate. Such implementation can include that when separately controllable voltages are provided to at least some of the linear electrodes, a gradient electric field is provided within the electro-optic material to cause the electro-optic material to have a refractive index gradient. The refractive index gradient can be controlled by varying the magnitude of the separately controllable voltages provided to at least some of the linear electrodes.

Eyewear including an optical functional member, control electronics, and a sealed electrical connective element connecting the electronics to the optical functional member. The connective element can directly connect the electronics to the optical functional member, or can connect through an intermediate contact, e.g., a plug-and-receptacle. The connective element can be routed from the electronics, around a rimlock of the eyewear to the optical functional member. The connective element can be a conductive compressible member, such as conductive rubber. In some embodiments, the connective element can be a multiconductor cable.

A film suitable for use in an ophthalmic system is provided. The film may selectively inhibit blue light within the wavelength range of 400 nm to 460 nm to reduce phototoxic light to the eye while maintaining photopic vision, and may be color balanced to allow for the system into which the film is incorporated to be perceived as colorless to a viewer observing and/or using the system. The system may have a photopic and scotopic luminous transmission of 85% or more and a phototoxicity ratio of less than 80%. When used in an ophthalmic system or other system disposed between an observer's eye and a light source, the film may reduce the flux of blue light to the internal structures of the eye while reducing or minimizing dilation of the pupil.

An ophthalmic lens is presented in which the lens includes a progressive addition legion and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which is less than a user's neat viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise ale reduced significantly.

An improved device and method for manufacturing electro-active spectacle lenses comprising electronic, electro-active optical, and bulk refractive optical elements is presented. In this method, electronic and electro-active optical elements are mounted to an optically transparent and mechanically flexible integration insert which is separate from any bulk refractive optical element(s). This method is advantageous for the manufacture of such spectacle lenses in that it allows for the mass production of many of the individual elements and enables the integration of the insert with the bulk refractive optical element(s) by multiple means. One such approach involves attaching the insert with a transparent adhesive to a rigid optical substrate and then encapsulating it by means of surface casting. Alternatively, the insert may be placed between the surfaces of a mold filled with an optical resin and encapsulated within the bulk refractive element as the resin is cured.
摘要:
Techniques and assemblies for light ray steering are described. A method for directing light rays includes steering the light rays using a static prism and controllably steering the light rays using an electro-optic prism, such that the combination of the light ray steerings from the static prism and the electro-optic prism substantially steer the light rays to impinge on a light focusing element at a predetermined angle. The electro-optic prism includes a first electrode positioned on a first substrate, a second electrode positioned on a second substrate, and an electro-optic material positioned between the first and second electrodes. The first electrode includes multiple substantially parallel linear electrodes. Applying multiple voltages to some or all of the multiple substantially parallel linear electrodes generates a refractive index gradient across the electro-optic prism. The direction of solar rays exiting the electro-optic prism is controllable by controlling the refractive index gradient. The method further includes receiving the light rays at the light focusing element and focusing the light rays, after the light rays have passed through the static prism and the electro-optic prism.
