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.
