title: The importance of the diffusive transfer of tints in the technology of tinting of soft contact lenses.
abstract: This paper deals with the kinetics of tint transfer in soft contact lenses. A mathematical model taking into account both diffusion and chemical reactions is proposed and physicochemical parameters are determined. It is shown that bulk tinting is more effective in practice than surface tinting.
