Abstract: The present invention relates to a thermosetting composition for the manufacture of an ophthalmic lens which efficiently absorbs light rays without degradation of the light-absorbing additive, said composition comprising an allyl monomer or oligomer, a catalyst, at least one light - absorbing additive contained in nanoparticles which are dispersed in said allyl monomer or allyl oligomer. The present invention also relates to the use of said composition and to the ophthalmic lens obtained from said composition.
