  • PROCESS FOR MANUFACTURE OF A THERMOCHROMIC CONTACT LENS MATERIAL
    Publication number: 20150115484
    Abstract: Disclosed in this specification is a process for manufacturing a thermochromic contact lens. The process includes (1) selecting a photoinitiator that absorbs at a first wavelength and at least one thermochromic dye that displays substantial absorption at the first wavelength when the dye is at a first temperature and exhibits at least an 80% reduction in absorbance at the first wavelength at a second temperature, (2) maintaining the reaction mixture at the second temperature and (3) providing cure light that includes the first wavelength.
