ABSTRACT:
An ophthalmic lens contains inserts (26, 28) for projecting an image towards the user's eye. The lens is treated by coating the surface order to attenuate light reflected on the treated surface from the inside of the lens. Coating the surface of the lens attenuates the parasitic images formed by rays reflected on the coated surface and projected by the insert.
