Abstract
A pair of electronic eyeglasses includes an eyeglasses frame and an eyeglasses lens mounted within the eyeglasses frame. At least one femtoprojector is embedded within the eyeglasses lens. The femtoprojector includes an image source and an optical system that projects an image from the image source onto the retina of the wearer. The femtoprojector is small enough that is does not significantly interfere with the wearer's view through the eyeglasses lens.
