Systems and methods for forming a mold-bonded lens

A method of forming a shaped multi-element lens, the method comprising:

• forming a first optical element of the lens from a first material using a compression mold, the first material having a first transition temperature Tg1, and the first optical element having a first optical prescription surface and a second surface;
• providing a second material adjacent to the first optical prescription surface, the second material having a second transition temperature Tg2 that is a lower temperature than the first transition temperature Tg1;
• and
• forming a second optical element using the compression mold, the second optical element having a third optical prescription surface bonded to the first optical prescription surface of the first optical element, wherein said forming the second optical element comprises heating the second material to a temperature less than the first transition temperature Tg1 and greater than the second transition temperature Tg2.

A method of forming a shaped multi-element lens, the method comprising:

• providing a first material in a compression mold, the first material having a first transition temperature Tg1;
• applying pressure and a first heat to the first material to form a first optical element of the lens, the first optical element having a prescription surface;
• placing a second material in the compression mold adjacent to the prescription surface of the first optical element, the second material having a second transition temperature Tg2 that is a lower temperature than the first transition temperature Tg1;
• applying pressure and a second heat to the second material to form a second optical element bonded to the prescription surface of the first optical element, the second heat being greater than the second transition temperature Tg2 and less than the first transition temperature Tg1.
