An electronic contact lens contains electrical components connected by an electrical interconnect. The electrical interconnect has a flat body, with electrical conductors running length-wise along the body. The flat body is oriented perpendicular rather than parallel to the inner and outer surfaces of the contact lens to reduce a visible profile of the interconnect, reducing the amount of light blocked from entering the eye. The body has a curvature shaped to conform to the curvature of the contact lens. As examples, the interconnect may be connected with an electrical component using a tab perpendicular to the flat body of the interconnect, or by forming an edge connection with electrical contacts of the component located along an edge of the component, or through one or more exposed vias formed on the component.

Electrical interconnects within electronic contact lenses

A variety of femtoprojector optical systems are described. The optical bodies for the systems may be made in batches by wafer-level optics. Each individual system may be made small enough to fit in a contact lens. In some designs, the optical systems include a solid transparent body with a curved primary mirror, a secondary mirror, an entrance window, an exit window, and at least one groove. The grooves function as a light trap that reduces the amount of stray light exiting the body of the optical system. The grooves may also create a snap point which allows removal of individual bodies from the wafer through controlled breakage. The designs may also include various light blocking, light-redirecting, absorbing coatings, or other types structures to reduce stray light.
