Abstract

Предложены устройство и способ отливки линзы без использования уплотнительной прокладки, которые могут быть использованы для формирования линз всевозможных геометрических форм с любой оптической силой. В них используют ленту (20) из эластомера, которую обертывают вокруг ребер двух матриц (40, 50) для создания рукавообразной конструкции, которая, в свою очередь, взаимодействует с матрицами (40, 50) и образует формовочную полость (31). Кроме того, эта рукавообразная конструкция не сминается и не дает усадку в течение процесса полимеризации линзы. Вместо этого, она дает возможность матрицам (40, 50) скользить внутри нее вдоль оси, обеспечивая компенсацию какой бы то ни было усадки, которая возникает во время процесса полимеризации линзы.Международная заявка была опубликована вместе с отчетом о международном поиске.
