Abstract
The invention relates to a fabrication process for molding a contact lens evincing the required optical properties. This method consists in designing a mold (1,2) with a high thermal inertia, transparent to, or little absorbing electromagnetic waves with wavelengths between 1 micron and 10.sup.-6 microns, in developing a base composition from polymerizing double-bond monomers which are absorbing with respect to these waves and in securing the polymerization of the composition inside the closed mold by irradiating with the above-cited electromagnetic waves at a power density such as to keep the temperature approximately less than 40.degree. C. at the mold level.
