Latest Patents
Kevin Michael Niemi holds a patent for "Optical articles comprising photochromic poly(urea-urethane)." This patent describes a process for producing a photochromic eyewear lens. In one embodiment, a layer of modified photochromic poly(urea-urethane) is formed by combining photochromic material with the reaction product of a polyurethane pre-polymer and a mixture of diethyltoluene diamine and one or more polyols, along with a catalyst. The mixture contains both NH and OH reactive groups, ensuring that at least 0.04 equivalent weights of OH reactive species are available for reaction with each 1.0 equivalent weight of excess NCO reactive species in the pre-polymer. The resulting lens exhibits faster fade-back rates and improved photochromic performance compared to lenses made with non-modified poly(urea-urethane).
