Abstract
The method provided consists in subjecting at least one lens to selective heating acting largely on particles of liquid held on the lens, the heating action being such as to cause the particles of liquid to evaporate off. Also provided is a drying unit comprising a drying chamber in which at least one optical lens can be positioned and means for producing microwaves and directing them at at least one lens placed in the drying chamber. <IMAGE>
