The optical lens (10) has a lens element (12) on which several layers (16) with an anti-static coating (14) are formed for generating an anti-static effect. Two adjacent layers (18,20) are formed with respect to the lowermost layer (22) and an upper layer (30). The stoichiometrically formed layer (18) is made of titanium oxide with specific amount of oxygen, and an aluminum oxide layer (20) is formed over the titanium oxide layer (18). An independent claim is included for method for formation of several layers of lens element. |
