Molds for making ophthalmic devices |
摘要 |
Ophthalmic lens are made by reacting a lens forming mixture in a mold to form a polymer. The polymer is then demolded from the mold and processed into a completed lens. The molds are made of at least two parts, a first part having a surface for forming the polymer into a portion of the lens and a second part having a surface for forming the polymer into a portion of the lens. The first and second parts of the mold each have different surface energies.
