Method and apparatus for making and coating a plastic lens. Oxygen barrier containing photoinitiator is used to cure incompletely cured lens portions. Radiation pulses are used to control lens curing rate. Lens is posted while in a mold cavity using a conductive heat source. Air may be directed toward the mold cavity to help remove heat form the lens. An in-mold scratch resistant coating may be formed from two separate material which both contain a photoinitiator.
