METHOD FOR ENGRAVING A LENS

摘要

The invention relates to a method for engraving a polymer lens that comprises displacing under a load an abrasive tool on a surface of the lens where said abrasive tool follows a continuous trajectory (1) comprising loops (2). The invention also relates to a method for making a polymer lens comprising the above-mentioned lens engraving step and at least one subsequent step that involves heating up to a temperature higher than the glass transition temperature (Tg) of the polymer of the lens.
