1. A method of producing a silicone hydrogel contact lens, comprising:

  • exposing a contact lens mold assembly, comprising a silicone hydrogel lens precursor composition, to ultraviolet light at an ultraviolet light intensity effective in forming a polymerized silicone hydrogel contact lens, characterized in thatthe ultraviolet light intensity measured at a surface of the contact lens mold assembly is greater than 20 μ

    W/cm2 and less than 4000 μ

    W/cm2.
