Abstract

La présente invention concerne une lentille multifonction qui présente des fonctions de circulation de larmes et de circulation d'oxygène. Selon la lentille de la présente invention, un trou de circulation de larmes est percé dans un corps en une position correspondant à une partie dans laquelle la sclérotique et la rétine d'un globe oculaire sont reliées l'une à l'autre lorsque la lentille est utilisée. Par conséquent, des larmes et des nutriments sont facilement fournis à l'intérieur et à l'extérieur de la lentille. Une lentille auxiliaire pour la correction d'une cornée est également disposée de façon fixe sur une partie centrale de la lentille afin d'empêcher des effets secondaires de se produire du fait du mouvement et du décentrage de la lentille auxiliaire.
