The disclosure is related to a new soft contact lens with edge to edge photochromic material where geometry of the optical region and the peripheral region of the lens are optimized to give the best cosmetic effect on eye. The vision correction component and the mechanical component of that soft contact lens are designed independently from each other. The design of each component, vision and mechanical, is achieved by the mean of using diffractive optics.

An apparatus includes a container, a plurality of lights and a circuit. The container may comprise an outer shell comprising a material configured to protect contents of the apparatus and an inner surface. The outer shell may be configured to open to enable the contents to be placed on the inner surface. A cavity may be formed within the container when the outer shell is closed. The plurality of lights implemented on the inner surface may each be configured to adjust a characteristic of light output in response to a signal. The circuit may be configured to generate the signal in response to an input. The circuit may be implemented between the outer shell and the inner surface. A reactive material of the contents of the container may be configured to change appearance in response to the characteristic of light.

A method of making an optical article having a gradient tint and a gradient polarization. The method includes providing an optical element including a coating having at least one alignment zone. A dye composition is contacted with the coating. The dye composition includes at least one of: a dichroic dye, a photochromic-dichroic dye, or a combination thereof to diffuse at least a portion of the dye composition into the coating at a predetermined concentration gradient along at least a portion of the coating to provide the gradient tint and the gradient polarization. A kit for making an optical article having a gradient tint and a gradient polarization. An optical article prepared from a method for making an optical article having a gradient tint and a gradient polarization.

An apparatus comprises a support structure. The apparatus also comprises a plurality of sensors positioned on the support structure. The apparatus also comprises a camera positioned on the support structure. The camera has a field of view that includes an eye of a user. The apparatus also includes one or more processors and memory. The memory stores instructions that, when executed by the one or more processors, cause the processors to detect ambient condition data using the plurality of sensors. The processors also capture imaging data that includes the eye using the camera. The processors determine a first predefined state of the eye based on the detected ambient condition data and the captured imaging data. The processors further dispense a fluid proximate to the eye in accordance with the first predefined state of the eye.

An optical element includes a first layer, a second layer, and a fluid. A first surface of the first layer is configured to change hydrophobicity in response to incoming activation light. Absorbing molecules in the fluid are repelled or attracted to the first surface in response to the hydrophobicity of the first surface.

The invention relates to filter dedicated to protect eye cone cells and method associated. The eye cone cells protecting filter is intended to be applied to a transparent surface and to filter incident light for preventing eye cone cells of a user, from damages due to illumination at physiological light levels on the eye of said user, and having spectral characteristics to i) filter light wavelengths between 405 and 465 nanometers, and ii) transmit a filtered light reaching the eye cone cells and having a harmfulness on said eye cone cells under a predefined maximum threshold.
