Time-intensity modulated UV cure for optical lens forming material

摘要

The present invention relates to a process for effectively curing a lens forming material to form a lens, preferably a contact lens. In particular the present invention relates to a modulated UV/VIS irradiation curing process, preferably using UV light, wherein the lens forming material is first cured with a very high intensity for a first short time period and then with a significantly lower intensity for a significantly longer time period.
