Nanovided spacer materials and corresponding systems and methods

A head-mounted display, including:

• a display;
• a first optical component comprising a non-patterned surface and a patterned surface having a periodicity of about one nanostructure every 10 nm to 500 nm;
• a second optical component spaced from the first optical component, the second optical component comprising a non-patterned surface and a patterned surface having a periodicity of about one nanostructure every 10 nm to 500 nm;
• and
• a polymer material that defines a plurality of nanovoids, each having a diameter of approximately 1000 nm or less, and serves as a buffer between the first optical component and the second optical component, wherein:
• a first surface of the polymer material is proximate to and coupled to the patterned surface of the first optical component;
• and
• a second surface of the polymer material is proximate to and coupled to the patterned surface of the second optical component.

A method, including:

• positioning a first optical component comprising a non-patterned surface and a patterned surface having a periodicity of about one nanostructure every 10 nm to 500 nm;
