  • Patent number: 9772500
    Abstract: A double-layered liquid crystal lens in which two liquid crystal layers are disposed, and a 3D display apparatus. In a 3D display mode, under control of an electric field, liquid crystal molecules of a first liquid crystal layer are deflected to form a plurality of first lenticular lens structures. In case of switching from the 3D display mode into a 2D display mode, under the control of an electric field, liquid crystal molecules in a second liquid crystal layer are deflected to form a plurality of second lenticular lens structures; the second lenticular lens structures are mirror symmetric to the corresponding first lenticular lens structures, so as to compensate a phase delay of a light modulated by the first lenticular lens structures, such that the light passes through the double-layered liquid crystal lens without deflection, and thus a normal 2D display state is realized.

  • Patent number: 8641191
    Abstract: An ophthalmic lens is presented in which the lens includes a progressive addition region 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 near 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 are reduced significantly.
