Abstract
A liquid lens fluid composition includes a polyphenyl ether molecule having from 2 to 7 aromatic rings, where the rings include ortho substitutions, meta substitutions, or a combination of ortho, meta, and para substitutions. Inter-ring linkages may include sulfur or oxygen. The liquid lens fluid composition may be characterized by a refractive index over the visible spectrum of at least 1.4, a viscosity at room temperature of less than approximately 1000 cP, and a freezing point of less than approximately −10° C.

A liquid lens fluid composition comprising:
- a polyphenyl ether molecule having from 2 to 7 aromatic rings, wherein the aromatic rings comprise ortho substitutions, meta substitutions, a combination of ortho and meta substitutions, or a combination of ortho, meta, and para substitutions, and one or more inter-ring linkages comprise sulfur.
A liquid lens fluid composition comprising:
- a polyphenyl thioether molecule having from 2 to 7 aromatic rings, wherein all the rings comprise ortho substitutions or meta substitutions.
A variable focus lens comprising:
- a transparent wall member;
- a transparent distensible membrane located over at least a portion of the transparent wall member;
- and
- a layer of a liquid lens fluid composition located between the wall member and the distensible membrane, wherein the liquid lens fluid composition comprises a polyphenyl ether molecule having from 2 to 7 aromatic rings, the rings having ortho substitutions, meta substitutions, a combination of ortho and meta substitutions, or a combination of ortho, meta, and para substitutions.
