ADDITIVE MANUFACTURING FOR TRANSPARENT OPHTHALMIC LENS |
摘要 |
The present invention describes 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, - 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. |
