Abstract:
1. A manufacturing method of a contact lens package in which a soft contact lens and a storage solution are hermetically sealed in a housing area, comprising: preparing a silicone hydrogel contact lens as the soft contact lens, wherein a diameter of the prepared silicone hydrogel contact lens is smaller, by a predetermined amount, than an intended diameter of the silicone hydrogel contact lens after a high pressure steam sterilization processing in a presence of a phosphoric acid; preparing the storage solution so as to contain the phosphoric acid; sealing the silicone hydrogel contact lens together with the storage solution containing the phosphoric acid in the housing area; and then performing the high pressure steam sterilization processing, thereby increasing the diameter of the silicone hydrogel contact lens to the intended diameter.
