  • Methods of forming contact lenses to reduce the transmittance of light
    Patent number: 11072137
    Abstract: A method of preparing and using a contact lens is disclosed. In one step, a light-absorbing dye solution, comprising a light-absorbing dye disposed in a solution, is dispensed onto a contact lens. In another step, the light-absorbing dye is reacted with the contact lens so that the contact lens permanently contains the light-absorbing dye. The transmission of light of a certain wavelength through the contact lens is reduced due to the reacted light-absorbing dye permanently contained within the contact lens.
