Abstract:
A contact lens (4) comprises a solid component capable of imparting shape and structure to said lens, and a liquid component, at least partially contained in the solid component, capable of favouring the compatibility between said lens and the eye of a user of said lens, wherein the liquid component comprises a solution capable of being used as a lachrymal substitute.
Abstract:
An aspherical contact lens (1), comprising an optical zone (4) and an inner region (5) of the optical zone including the optical axis (X) of the lens. The inner region (5) is shaped in such a way that the dioptric power of every point thereon varies substantially linearly in relation to the distance of that point from the optical axis.
Abstract:
A contact lens (1) is described which comprises an optical body (3) in which a plurality of reflective particles (2) are dispersed; at least 75% of the particles have dimensions distributed variously between 10 and 60 microns.
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:
An iris region (4), which is to be superpose, in use, on the iris (4a) of the user, and also a peripheral ring (5), which is arranged annularly around the iris region (4) and which is to be superposed, in use, on a sclera portion (5a) of the user, are defined on a cosmetic contact lens (1). The lens comprises means that are opaque to light and that are capable of conferring an aesthetic effect on the eye of a user of the lens, which opaque means are concentrated at the location of the peripheral ring (5).
Abstract:
A cosmetic contact lens comprising an optical body (3) and a plurality of glitter particles (2) distributed in the optical body is described. The glitter particles are preferably prismatic.
Abstract:
A contact lens for correcting sight defects, in particular myopia defects, is described and comprises an optical body (2) of predetermined outside diameter (D o ) and optical axis (Z), in which a preselected nominal dioptric correction factor is provided. The lens comprises a central optical zone (7) with a diameter (D 3 ) smaller than the outside diameter (D o ) and having a negative dioptric hypercorrection relative to the nominal factor, a first annular optical zone (8) adjacent the central optical zone (7), and a second annular optical zone (9) adjacent the first annular zone (8), the nominal dioptric correction factor being provided in the first zone (8) and a dioptric hypercorrection relative to the nominal factor being provided in the second annular zone (9).
