FIELD: physics.
SUBSTANCE: free form ophthalmic lens comprises a first optical zone portion comprising multiple voxels of polymerised crosslinkable material containing a photoabsorptive component. The optical zone portion comprises a first area having a first refraction index and a second area having a second refraction index; and a second portion comprising a layered volume of crosslinkable material polymerised beyond the gel point of the crosslinkable material.
EFFECT: obtaining ophthalmic lenses with a free form surface and areas with different refraction indices, which enable to correct vision by changing the focal distance.
