Abstract
An electronic contact lens includes multiple femtoprojectors within the contact lens. Different femtoprojectors project images onto different portions of the retina. The images can be aligned by an alignment circuit within the contact lens. The alignment circuit can adjust the physical position or orientation of one or more femtoprojectors. Additionally, the alignment circuit can configure a location within a femtoprojector array from which an image is projected. A user can provide an input to align the femtoprojectors. For instance, a user can provide an input to adjust a location from which a first femtoprojector projects a test image until the test image is aligned with a test image projected by a second femtoprojector. The alignment circuit can, based on the user's input, determine alignment information for the femtoprojectors, and the contact lens can project subsequent images based on the alignment information.
