Abstract:
The present invention relates to processes for transferring a coating borne by a carrier onto at least one surface of the substrate of an optical article. Specifically, the invention relates to processes for transferring any kind of patterned layer having a refractive index profile from a carrier to the surface of an optical article. The invention allows for manufacture of optical articles presenting high transmittance, low haze, and excellent adhesion performances, and in particular vision corrective optical articles that are customized and optimized to the patient's individual requirements. The invention also contemplates optical articles made by such methods.
