摘要 |
A method of forming a contact lens within a mold is provided. A coating of a polyionic material(s) is applied to the mold before forming a lens therein. The coating can be applied by spraying or dipping the mold within a solution(s) of polyionic materials. Various other additives can also be applied to the mold. The coating can then be transferred to a contact lens formed within the mold such that the resulting lens has altered surface properties.
