A camera module, a molded circuit board assembly, a molded photosensitive assembly and manufacturing method thereof are disclosed. The camera module includes a molded base which is integrally formed with a circuit board through a molding process, wherein a photosensitive element may be electrically connected on the circuit board and at least a portion of a non-photosensitive area portion of the photosensitive element is also connected by the molded base through the molding process. A light window is formed in a central portion of the molded base to provide a light path for the photosensitive element, wherein a cross section of the light window is configured to have a trapezoidal or multi-step trapezoidal shape which has a size increasing from bottom to top to facilitate demoulding and avoiding stray lights.

The present disclosure provides a smart contact lens and a light-transmitting body thereof. The smart contact lens includes a light-transmitting body, an image-sensing module and an image display module. The light-transmitting body has a first view window and a second view window. The image-sensing module diverges from the second view window by a predetermined horizontal distance. The image display module diverges from the first view window by a predetermined horizontal distance. The light-transmitting body has a first transmission path formed between the second view window and the image-sensing module, and a second transmission path formed between the first view window and the image display module. An external image source received by the second view window is transmitted to the image-sensing module through the first transmission path, and an internal image source generated by the image display module is transmitted to an eyeball through the second transmission path.

Methods of forming a lens include forming components on a lower substrate. The components are sealed on the lower substrate with a sealing layer. An upper substrate is formed over the sealing layer. The lower substrate is polished to a lower lens curvature.

Techniques and mechanisms for fabrication of an eye mountable device. In an embodiment, an apparatus includes two curved lens portions and a flexible arm structure that extends between, and is anchored to, each of the two curved lens portions. The eye mountable device is formed at least in part by manipulation of the curved lens portions using the arm structure. Flexibility of the arm structure accommodates positioning of one curved lens portion to overlap the other curved lens portion. A lens of the eye mountable device is formed by the curved lens portions. In another embodiment, an enclosure formed by the lens has disposed therein an accommodation actuator.

An electronic device can comprise a first electronic module; a second electronic module; and a hermetic electric interconnect to hermetically couple them. The hermetic electric interconnect can comprise a bottom metal layer; a bottom insulating layer, deposited on the bottom metal layer to insulate the bottom metal layer; an interconnect metal layer, deposited on the bottom insulating layer, and deposited to form a bottom sealing ring; and patterned to form electrical connections between contact pads, and to form a middle sealing ring; a patterned top insulating layer, deposited on the interconnect metal layer to insulate the interconnect metal layer; and patterned to form feedthrough holes; and a top metal layer, deposited on the top insulating layer to start forming contacts by filling the feedthrough holes; and patterned to complete forming contacts through the feedthrough holes, to form a separate barrier layer, and to complete forming the top sealing ring.

A method for superposing a first ophthalmic lens having a first face and a second ophthalmic lens having a second face in order to build an optical assembly delimited by the first and second faces. The method includes detecting respective positions in space and shapes of the first and second ophthalmic lenses, by using at least one sensor, detecting a first reference point on the first ophthalmic lens and a second reference point on the second ophthalmic lens, based on these respective positions in space and shapes, and modifying the respective positions so as to superpose the first and second reference points.

An apparatus to treat refractive error of an eye comprises an electroactive component configured to switch between a light scattering or optical power providing configuration to treat refractive error of the eye and a substantially transparent configuration to allow normal viewing. The electroactive component can be located on the lens away from a central axis of the lens to provide light to a peripheral region of the retina to decrease the progression of myopia. The electroactive component can be located on the lens away from the central axis of the lens in order for the wearer to view objects through an optical zone while the electroactive component scatters light. The electroactive component can be configured to switch to the substantially transparent configuration to allow light to pass through the electroactive component and to allow the lens to refract light to correct vision and allow normal viewing through the lens.

An eyewear lens according to the present invention is configured so as to be provided with: a transparent first substrate having a principal surface; a second substrate disposed facing the principal surface, the transmittance thereof with respect to light in a predetermined wavelength region being different from that of the first substrate; an electric element in which optical characteristics thereof is changed by electrical control, the electric element being provided between the first substrate and the second substrate; and an adhesive layer provided between the first substrate and the second substrate.

A method of forming packaged lens modules is disclosed which includes: securing first ends of a plurality of lens modules equidistantly on a first mold plate; providing a second mold plate matching with second ends of the lens modules and securing the second mold plate on the second ends of the lens modules; filling a black material in gaps between the lens modules; and removing the first and second mold plates after the black material is cured and performing a dicing process. The method can effectively block lens openings to protect lenses from being contaminated and can eliminate the need for adhesive application and removal generally performed on second ends of the lens modules, thereby resulting in time savings and an efficiency improvement. Additionally, a height of the resulting packaged lens modules can be modified for back focal length compensation thereof by changing the size of the second mold plate.
