Abstract
Patente de Invenção:<B>"MéTODO E COMPOSIçãO PARA A FABRICAçãO DE LENTES OFTáLMICAS".<D> Método de cura para lentes oftálmicas ou peças brutas de lente semi - acabadas, em que uma resina curável é, primeiramente, exposta à radiação na faixa de comprimento de onda de 400 - 800 NM e, subsequêntemente, submetida ao calor ou à radiação de comprimento de onda ou intensidade diferente usado na primeira etapa. A resina polimerizável compreende, preferivelmente: (1) um primeiro fotoindicador que é ativado por radiação na faixa de comprimento de onda 400 - 800 NM e (2) um indicador térmico que é ativado por calor, ou um segundo fotoindicador que é ativado por radiação de comprimento de onda ou intensidade diferente daquele usado para ativar o primeiro fotoindicador.Invention Patent: <B> "METHOD AND COMPOSITION FOR THE MANUFACTURE OF OPHTHALMIC LENSES". <D> Curing method for ophthalmic lenses or semi-finished lens blanks, in which a curable resin is first exposed to radiation in the wavelength range of 400 - 800 NM and subsequently subjected to heat or radiation of different wavelength or intensity used in the first stage. The polymerizable resin preferably comprises: (1) a first photoindicator that is activated by radiation in the wavelength range 400 - 800 NM and (2) a thermal indicator that is activated by heat, or a second photoindicator that is activated by radiation wavelength or intensity different from that used to activate the first photoindicator.
