摘要:
An embryonic optical apparatus including a first lens component including a first surface and a second surface on an opposite side of the first lens component from the first surface, and a second lens component comprising a flexible element, wherein the flexible element of the second lens component comprises a first region that is variably movable towards and away from the first surface, thereby dynamically adjusting an optical power of the embryonic optical apparatus with respect to a light path through the first region and the first surface, and wherein the embryonic optical apparatus is configured such that at least a portion of the second surface is permanently alterable to permanently define an optical power of the first lens at least a second region of the second surface, the second region being optically aligned with the first region, thereby resulting in a prescription-quality ophthalmic optical apparatus.
摘要:
A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

This invention relates to temples or end-pieces of temples for eyeglass frames. The temples are disclosed as having a wide variety of electrical and/or electronic components housed therein. Temples and hinges are also disclosed which attach to either the eyeglass frame itself or to the surface of a lens and which break apart from its attachment upon an impact without damage to the temple, the hinge, the frame, or the surface of the lens. A hinge is also disclosed for connecting a temple having a power source to an eyeglass frame and for providing an electrical connection with the frame only when the temple is opened.
摘要:
An electro-active phoropter and a method of using the electro-active phoropter to measure a patient's vision prescription is disclosed. The electro-active phoropter includes a series of individually addressable electro-active lenses. The lenses have either a positive or negative optical power when an electrical potential is applied across the lens and a neutral optical power when no electrical potential is applied across the lens. Each lens provides an optical power that is part of a net optical power of the series of lenses when a patient views through the phoropter. The optical power of the phoropter can be incrementally adjusted by changing the distribution of the electrical potential across the different lenses of the series to provide increasing or decreasing optical power until a patient achieves a desired level of clarity and a vision prescription has been determined.
摘要:
A lens system for dynamically correcting refractive error is disclosed, the lens system comprising: a lens having at least one electro-active element having a refractive property that is alterable, the lens being capable of being shaped to fit a housing without hindering performance of the electro-active element, a controller in communication with each of the at least one electro-active element thereto, and an input generator adapted for generating an input signal and transmitting the input signal to the controller, the input signal being generated based at least in part on an input parameter.

摘要:
Electro-active multi-focal spectacles are disclosed. The spectacles have a stack of at least two electro-active regions. The electro-active regions produce a plurality of viewing correction zones. The spectacles also have a controller for independently activating the electro-active regions to produce viewing correction zones. An electro-active multi-focal spectacle having a blending zone is also disclosed. The blending zone provides a transition of optical power between viewing correction zones.
摘要:
A low power indicator for electro-active spectacle lenses is presented in which the low power indicator is a part of a controller for the electro-active spectacle lenses or is operably connected to the controller. The low power indicator may generate a signal when the power of the power source for the electro-active spectacle lenses is low. The signal may be used by the controller, or other circuitry to activate an indication to a user of the lenses that the power is low. Such an indication may be periodically activating and deactivating one of an optical power of the electro-active lenses, a vibration source, a visible light source, or an audible sound source.
