Abstract: Overmolding or overcasting one portion of a reflective waveguide to another portion achieves bonding of components of the reflective waveguide without the need for an index-matched adhesive or an alignment platform for bonding. In embodiments in which one portion is overmolded to the other, the materials used to form the portions are selected such that the material used to form a first portion has a glass transition temperature (Tg) that is higher than the Tg of the material used to form a second portion. In embodiments in which one portion is overcasted to the other, the materials used to form the first portion and the second portion are thermosetting resins and are selected such that both materials have solubility parameters that approximately match each other.

Abstract: A spectacle lens is disclosed that includes compound microlenses arranged in a pattern. A compound microlens includes an on-axis microlenslet and an off-axis sub-lenslet located on the on-axis microlenslet.
