摘要: An improved method for imparting a tint or color to soft, hydrogel contact lens by uniformly dispersing dye throughout the lens. The is water-soluble halotriazine dye. reacted with hydrophilic monomer prepare reactive containing predominantly monofunctionality. then subjected polymerization in presence of homogeneous solution under conditions yield polymer from which formed. becomes bonded during polymerization. finished does not require soaking an aqueous impart desired Additionally, dispersed according leach out migrate within Furthermore, need be washed base bond
