Abstract

"LENTE COMPOSTA MONOFOCAL E MOLDE". A invenção descreve uma lente composta monofocal e o molde para sua fabricação, sendo que tal lente composta monofocal possuí um ponto de dioptria para leitura distante e um ponto de dioptria para leitura próxima com dioptrias diferentes, que são moldados integralmente para possuírem o mesmo ponto ótico central e o molde possui duas áreas divididas pelo ponto ótico central, cada uma formando uma superfície periférica interna com uma diferença de curvatura e espessura que corresponde à diferença de dioptria, de tal maneira que trabalhos próximos como a leitura e trabalho no computador podem ser realizados sem qualquer problema e a fadiga dos olhos causada pela falta de correspondência de focos pode ser prevenida.
