FIELD: medicine.
SUBSTANCE: disclosed is a contact lens system, which comprises a contact lens containing a photosensitive chromophore, and a package surrounding the contact lens. Photosensitive chromophore has at least one active wavelength in range of 250 to 400 nanometres and at least one active wavelength in range of 400 to 450 nanometres. At each active wavelength the package has a transmission coefficient of not more than 99%.
EFFECT: use of this invention enables to stabilize the photosensitive chromophore against photodecomposition.
