Abstract

See full text

A method using additive manufacturing technologies and processes to manufacture a three-dimensional ophthalmic lens with a high management level of the homogeneity during the construction of the ophthalmic lens, through a control of two technical characteristics of voxel: the ability to modify their viscosity, and the ability to inter-diffuse together to provide a final homogeneous element. These two technical characteristics are managed by the choice of component(s) used to manufacture each voxel and by the kind of physical and/or chemical treatment apply to each of them.
