摘要：A plastic trial lens having a grip portion gripped when the lens is set in trialframes for trial lenses, an injection molded product for making the trial lenses, and a
mold assembly for molding the injection molded product are provided. In the injectionmolded product molded by means of the mold assembly in an injection compressionmolding machine, a grip portion and a liquid guided and collected area are moldedsimultaneously with a lens portion on a periphery of the lens portion. When the injectionmolded product is dipped into hard coat liquid, the hard coat liquid is guided in the liquidguided and collected area to drip down and the remaining liquid without dripping down iscollected in the liquid guided and collected area, thereby forming a coating film ofuniform thickness on the lens portion. The plastic trial lens which is integrally providedwith the grip portion is finished after the liquid guided and collected area is removed.
