Title:
コンタクトレンズ成形用モールド型
Document Type and Number:
Japanese Patent JP4783505
Kind Code:
B2
Abstract:
An ophthalmic lens mold includes a first mold (32) half having a front side and a back side. The front side (40) defines an optical surface. A second mold half (34) has a front side (42) defining an optical surface. Upon alignment of the first mold half with respect to the second mold half so that the front sides oppose each other, a mold cavity (96) is formed between the front sides to form an ophthalmic lens therein from a moldable material. The first mold half includes a first section (40) that transmits curing light (104) and that extends from the back side to the front side. The first section includes at least an area of the first mold half optical surface enclosed by an outermost circumference (72) of the ophthalmic lens. A second section (46) is comolded with the first section and blocks the light. The second section is disposed with respect to the first section so that the second section prevents the curing light incident to the back side from passing through the first mold half into an area of the mold cavity (96) extending from the first mold half front side (40) to the second mold half front side (42) surrounding and extending radially outward of a boundary that includes the ophthalmic lens circumference (72) and so that the first section passes the incident light to an area of the mold cavity bounded by and within the boundary.
