摘要 |
<p>The invention relates to a tinted polarizing optical element (1), including a polarizing assembly (5) consisting of at least a first layer (7) and a second layer (9) made of a thermoplastic or thermosetting material and sandwiching a polarizing film (11) therebetween, and to a method for manufacturing said optical element. The latter further comprises a third layer (13) made of a tinted thermoplastic material adhering, by means of injection, to the second layer (9), characterized in that the element includes a fourth layer (15) which is made of a crystal thermoplastic material adhering, by means of injection, to the third layer (13), and which is to be surfaced so as to achieve a corrective effect.</p> |
