ELECTRO-ACTIVE OPHTHALMIC LENSES COMPRISING LOW VISCOSITY LIQUID CRYSTALLINE MIXTURES |
摘要 |
An electro-active ophthalmic lens is presented in which the lens includes a progressive addition region having an add power and an electro-active element. The electro-active element is in optical communication with the progressive addition region and has an activated state and a deactivated state. The electro-active element also includes a liquid crystalline material disposed in a cavity having a diffractive surface relief structure. The liquid crystalline material has a low rotational viscosity. |
