Introduction | An electronic vision-therapy apparatus includes a frame, a lens module and a control unit. The lens module includes first and second liquid crystal lenses. The control unit is for controlling the first and second liquid crystal lenses to cooperatively generate and display a light filtering pattern. The light filtering pattern has an opaque part and a plurality of transparent parts. The control unit configures a part of the first liquid crystal lens that corresponds to the opaque part to allow only light having a first polarization to pass therethrough, and configures a part of the second liquid crystal lens that corresponds to the opaque part to allow only light having a second polarization orthogonal to the first polarization to pass therethrough. |
