PLASTIC TRIAL LENS, ITS INJECTION MOLDED ARTICLE AND ITS MOLDING APPARATUS

摘要

A plastic trial lens includes a pinching portion for pinching when a lens is loaded to a trial frame. An injection molded article for the trial lens and a molding apparatus for molding the injection molded article are described, too. The injection molded article molded by the molding apparatus of an injection compression molding machine has a pinching portion and a liquid guide/reservoir portion around an outer peripheral portion of a lens portion that are molded simultaneously with molding of the lens portion. When the injection molded article is dipped into a hard-coat solution for dipping treatment, the hard-coat solution is guided into the liquid guide/reservoir portion and drops. The solution that does not drop stays in the liquid guide/reservoir portion, so that a coating film having a uniform thickness can be formed on the lens portion. When the liquid guide/reservoir portion is removed, a plastic trial lens equipped integrally with the pinching portion can be finished.
