Abstract

METODO DE FABRICACION DE LENTILLAS DE CONTACTO. CONSISTENTE EN POLIMERIZAR UNA COMPOSICION DE BASE EN UN MOLDE ESTANCO CERRADO QUE REPRODUCE EN HUECO LA FORMA DE LA LENTILLA. EL MOLDE SE REALIZA DE MATERIAL TRANSPARENTE O POCO ABSORBENTE CON RESPECTO A LAS ONDAS ELECTROMAGNETICAS, DE LONGITUD DE ONDA APROXIMADAMENTE COMPRENDIDA ENTRE 1 Y 10-6 MICROMETROS, Y CON INERCIA TERMICA MUY SUPERIOR A LA DE LA CANTIDAD DE COMPOSICION DE BASE NECESARIA PARA UNA LENTILLA. LA COMPOSICION DE BASE SE ELABORA A PARTIR DE UNO O DOS MONOMEROS CON DOBLES ENLACES POLIMERIZABLES, QUE TIENEN CARACTER ABSORBENTE CON RESPECTO A LAS ONDAS ELECTROMAGNETICAS CITADAS.
