Abstract

본 발명은, 렌즈의 앞면 및 뒷면중의 하나가 기본적인 처방의 Rx구형 원거리 광학배율에 상응하는 구형표면을 가진 환상디스크를 포함하는 중심영역을 한정하는 다촛점 동심원성 환상링렌즈에 관한 것이다. 다수의 환상링들은 중심영역을 둘러싸며, 교호적인 구형 근거리 및 원거리광학배율, 및 하나이상의 중간광학배율을 가진 환상링을 갖는다. 중간광학배율을 가진 환상링은 벤즈의 광학영역의 중심 또는 외부영역에 위치하고, 이의 광학배율은 중간거리에서 시각적인 예리함을 제공하기 위해 중간내지 원거리 및 근거리 광학배율이다. 중간광학배율을 가진 환상링은 렌즈의 광학영역의 중심 또는 외부어디에나 위치할 수 있고, 렌즈의 광학영역의 외부 가장자리로부터 제2의 환상링일 수 있거나 또는 렌즈의 광학영역의 바깥원주를 한정하는 최외곽 환상링일 수 있다. 상기 렌즈는 연질하이드로겔 콘택트렌즈와 같은 눈의 각막에 착용되는 콘택트렌즈 또는 안내렌즈일 수 있다.
