Abstract: A method for preventing or limiting the progression the myopia includes: providing a soft contact lens. The contact lens includes: a solid polymeric component, which is provided for conferring shape and structure on the contact lens and a liquid component which is distributed in the solid component, and which comprises tyrosine, at a concentration between 1 and 200 mg/l. The method further includes putting the soft contact lens on an eye of a patient so as to apply the compound on the eye.

Abstract: A soft contact lens (4) comprises a solid component, which is based on a polymer, and a liquid component which is distributed in the solid component and which comprises at least one compound which is selected from vitamin E, vitamin B2 and the respective derivatives thereof. The contact lens has a degree of transmission of type A ultraviolet radiation greater than 50% and a degree of transmission of type B ultraviolet radiation greater than 20%.

Abstract: A soft contact lens comprises a solid component, based on a polymer and a liquid component which is distributed in a substantially uniform manner in the solid component. The liquid component comprises an effective quantity of a compound selected from the group formed by tyrosine, derivatives of tyrosine, precursors of tyrosine and dopamine which is capable of preventing or at least limiting the progression of myopia of the eye.

Abstract: A method for introducing an active compound into a soft hydrated contact lens comprising the steps of: providing a hypotonic aqueous solution having an osmolarity value less than 150 mOsm and an effective quantity of that active compound, immersing the soft contact lens in the aqueous hypotonic solution, subjecting the contact lens immersed in the aqueous hypotonic solution to mechanical vibrations having a power greater than 100 mW for a predetermined time.

Abstract: A contact lens (1) comprises an optical zone (5) extending with a first diameter (A) about an optical axis (X) of the lens, and is provided with a first dioptric power and a central region (6), extending about the optical axis (X) with a second diameter (B), smaller than the first diameter, inside which is provided an optically inactive zone (7) with a diameter smaller than 0.5 mm.
