PHOTOCHROMIC FLUID FILLED LENSES AND METHODS OF MANUFACTURE THEREOF

摘要

A method of manufacturing a fluid lens assembly includes dissolving a photochromic additive in a solvent to form a solution, adding the solution to a fluid to form a photochromic fluid, stirring the photochromic fluid, degassing the photochromic fluid, introducing the degassed photochromic fluid into the fluid lens assembly, and sealing the fluid lens assembly. Another method includes encapsulating a photochromic additive in a vesicle that is soluble in a fluid for use in the fluid lens assembly, stirring the photochromic fluid, introducing the photochromic fluid into the fluid lens assembly, and sealing the fluid lens assembly. A fluid lens assembly includes a rigid lens, a membrane fluidly attached to the rigid lens to create a cavity therebetween, and a photochromic fluid disposed within the cavity.
