Abstract
A method for producing an ophthalmic lens comprised of a base lens and a film structure bound to said base lens includes a pressure-free heating. Said heating is performed after assembling the film structure with a semi-finished lens (), and before said semi-finished lens is machined for obtaining the base lens. Although a maximum heating temperature is higher than a glass-transition temperature of the semi-finished lens, no image distortion and optical aberration is produced for the final ophthalmic lens. The maximum heating temperature is also lower than a glass-transition temperature of the film structure.
