The invention generally concerns a method involving emitting polarization
light waves through an aperture with a dimension of maximum size lower
than or equal to 100 nm, wherein the aperture is circumferentially bound
by an opaque area that prevents the light waves from being propagated
outside the aperture during use, and wherein the emitted polarization
light waves (1) contact a material layer comprising a photosensitive
compound whose surface is located at a distance lower than 100 nm from
said aperture, and (2) induce a topographic modification of the material
layer. In this manner, a stable structure is printed in relief in the
material layer without requiring any additional development step. The
invention is applicable, in certain embodiments, to ophthalmic optics.
