Zusammenfassung:	Methods and apparatus for additive manufacture of an optical element corresponding with an energy transmissibility image. The optical element may include a contact lens or intraocular lens. The optical element may be formed via intermittent pinning of deposited polymerizable mixture, partial cure, and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with each respective area.
