Abstract
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.
