Abstract: UV absorbing appliances, such as contact lenses, are prepared by including at least one UV absorbing compound in the appliances. UV absorbing compounds can be water insoluble and/or reside in UV absorbing nanoparticles having a mean diameter less than 10 nm. The UV absorbing nanoparticles incorporate into an appliance by polymerizing a monomer mixture containing the UV absorbing nanoparticles to form an appliance comprising the UV absorbing nanoparticles. The UV absorbing compounds or the UV absorbing nanoparticles incorporate into an appliance by placing the appliance in a solution of the UV absorbing compound or a dispersion of the UV absorbing nanoparticles in a non-aqueous solvent that swells the appliance. The UV absorbing compound or the UV absorbing nanoparticles infuse into the swollen appliance and are retained within the appliance upon removal of the non-aqueous solvent.
Abstract translation: 通过在器具中包含至少一种UV吸收化合物来制备紫外线吸收器具，例如隐形眼镜。 UV吸收化合物可以是水不溶性的和/或驻留在平均直径小于10nm的UV吸收纳米颗粒中。 UV吸收纳米颗粒通过聚合含有UV吸收纳米颗粒的单体混合物结合到器具中以形成包含UV吸收纳米颗粒的器具。 UV吸收化合物或UV吸收纳米颗粒通过将该器具放置在UV吸收化合物或UV吸收纳米颗粒的分散体的溶液中而溶解在器具中，使其溶解在使水分膨胀的非水溶剂中。 UV吸收化合物或UV吸收纳米粒子注入溶胀的器具中，并且在除去非水溶剂后保留在器具内。
