  • Patent number: 5213760
    Abstract: A method for signaling a lens user when the user's lenses are overworn. The lenses have applied a handling tint, and the lenses are disinfected in an oxidant solution. The amount of tint added to the lens is such that after soaking the lens for a predetermined period of time in the disinfectant solution, over the expected lifetime of the lens, a noticeable change in the appearance of the handling tint is observed. If the lens is intended to have a fixed lifetime, and the lens is intended to be soaked in a disinfectant solution on a regular basis and for a fixed period of time for the lens lifetime, the amount of the handling tint in the lens can be adjusted such that the handling tint is bleached out or changes color after the lens undergoes regular disinfection within the predetermined lens lifetime.
