Abstract

"PROCESSO DE FABRICAR UMA LENTE DE FOCO VARIáVEL, RESPECTIVA LENTE DE FOCO VARIáVEL E PAR DE óCULOS TENDO UM PAR DE ABERTURAS PARA LENTE". Uma lente de foco variável compreende primeira e segunda membranas flexíveis (2) que são tensionadas e que definem uma cavidade (30) na qual é selado um óleo de silicone transparente (4). O ajuste da pressão ou volume do óleo na cavidade varia a distância focal da lente. Para fabricar a lente, a periferia de cada membrana (2) é engatada entre dois anéis (8, 10; 10, 12) de um conjunto de três anéis mutuamente engatados (8, 10, 12). Os anéis mutuamente engatados são conjuntamente crispados para tensionar as membranas (2) e selar a cavidade (30).
