Abstract
A method of deblocking a lens component () fixed on a thermoplastic block () of an ophthalmic lens block comprising the steps of: a) applying a pushing strain on the surface () of the lens component fixed on the thermoplastic block; b) providing a warm gas flow at the interface between the lens component () and the thermoplastic block; and maintaining the pushing strain during the step of providing the warm gas flow at the interface between the lens component and the thermoplastic block, wherein the stress applied to obtain the pushing strain of step a) is greater or equal to 0.1 MPa and/or less or equal to 1 Mpa, and wherein the temperature of the warm gas flow of step b) is greater or equal to 30° and/or less or equal to 70° C.
