Abstract
Methods for producing contact lenses from a polymerizable composition are provided. The methods generally include providing a carrier carrying a plurality of molds each of which contains a polymerizable composition. A chamber is provided which contains a light source providing light to the chamber effective to facilitate polymerization of the polymerizable composition. The molds in the carrier are exposed to the light in the chamber. During this exposing, the light source is monitored, for example, using digital addressable lighting interface (DALI) technology.
