摘要

PROBLEM TO BE SOLVED: To provide a degassing technique which improves effectiveness in both operation and maintenance, can be applied in in-line, and alleviates the problem of clearout. SOLUTION: This invention relates to a supplementary element which can be piled, is used in degassing a liquid ophthalmic lens monomer and relates to the lens obtained as a result. A module type degassing apparatus can be formed using an element which can be piled in at least one, and the in-line type degassing method using this can be implemented.
