Abstract
친수성 콘택트 렌즈를 성형하는 방법은 용매와 혼합된 친수성 단량체를 포함하는 렌즈 형성액을 제공하는 단계 및 2개의 금형 부분들 사이의 액체를 중합하는 단계를 포함한다. 본 발명의 개선은 약 100통이하의 온도에서 증발시켜 용매를 충분히 제거하는 것이다.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 짜 맞추기 전, 본 발명을 수행하는데 적합한 2개의 금형 부분을 나타낸 것이고,
제2도는 콘택트-렌즈-조형강을 형성시키기 위해 짜 맞춘 제1도의 금형 부분들을 나타낸 것이고,
제3도는 열려져 있는 제2도의 금형 부분들과 본 방법으로 형성시킨 콘택트 렌즈를 나타낸 것이고,
제4도는 본 발명에 따라 형성시킨 콘택트 렌즈에 착색제를 도포하는 것을 나타낸 것이다.
