Abstract

Se utiliza una computadora para calcular la localización de un objetivo, hacer a la medida el objeto para conformarse a las características del lente, el armazón, y el paciente de cada trabajo individual, y para compensar de una manera automática el paralaje en el aparato. Se proporciona una superficie de trabajo abierta conveniente para que el operador posicione el material del lente sobre una superficie no derrapante. El bloque se aplica a una fuerza limitada constante en un modo manual o automático de operación sobre el armazón o el centro óptico. Los desfasamientos para posicionar el material del lente se calculan dentro del bloqueador basándose en los datos del armazón y del paciente. Estos datos se pueden meter directamente, o se puede descargar desde una base de datos. Estos desfasamientos determinan la localización del objetivo en relación con las marcas ópticas sobre el material del lente. La cantidad que se desfasa al objetivo, se escala automáticamente para compensar el hecho de que el material del lente esté sobre una superficie de trabajo arriba del despliegue visual electrónico. Se exhibe un objetivo a la medida. El objetivo se escala para acoplarse con los anchos de segmentos para lentes multifocales, y proporciona una localización objetiva centrada con múltiples líneas horizontales para lentes de una sola visión, incluyendo a lentes progresivos. La escala del ancho elimina el juicio del operador para poner el 'globo del ojo' en el centro. Las múltiples líneas horizontales proporcionan una ayuda adicional para alinear lentes progresivos, en donde la distancia desde la 'cruz de montaje' hasta la línea horizontal del material del lente varía desde el fabricante. También se puede exhibir la forma del armazón para proporcionar una percepción del ajuste.
