Abstract
A method of forming an ophthalmic laminate lens, includes: forming a planar laminate () by adhering a first stretched polymer layer () to a first side of a thermoplastic elastomer layer (), and adhering a second polymer layer () to a second side of the thermoplastic elastomer layer (), the first stretched polymer layer () having a thickness greater than 250 pm, the second polymer layer () having a thickness greater than 250 pm, and the thermoplastic elastomer layer () having a thickness in a range of 15 μm to 150 μm; thermoforming the planar laminate () into a curved laminate (), the curve laminate () having a pre-molding curvature; arranging the curved laminate () in a mold (); and molding, via the mold set () at a predetermined temperature and a predetermined pressure, the curved laminate () with a polymer melt () into a curved lens, wherein a temperature of the polymer melt () is above a stretch temperature of the first stretched polymer layer ().
