Method for producing an ophthalmic lens comprising a base lens and a film structure

A method for producing an ophthalmic lens including a base lens and a film structure bound to a first optical surface of said base lens, the method comprising:

• /1/ obtaining a semi-finished lens, having the first optical surface and a temporary surface opposite to said first optical surface;
• /2/ obtaining the film structure;
• /3/ applying the film structure onto the first optical surface of the semi-finished lens, with layered connecting means arranged between said film structure and said first optical surface of the semi-finished lens;
• step /3/ being performed using a pressing device for producing pressure so as to push the film structure and the first optical surface of the semi-finished lens against each other;
• /4/ after step /3/ and after pressure has been removed:
• heating the semi-finished lens with the film structure connected to said semi-finished lens, up to a maximum heating temperature which is higher than a glass-transition temperature of a constituting material of the semi-finished lens and less than another glass-transition temperature of a material of the film structure;
• and
• /5/ after step /4/:
• machining the temporary surface of the semi-finished lens so as to obtain a second optical surface opposite to the first optical surface, thereby producing the base lens comprised in the ophthalmic lens, the machining causing said base lens to be thinner than the semi-finished lens.
