    摘要： An object of the present invention is to provide a contact lens for vitreous surgery that is highly durable to washing, disinfectants, sterilizing high-pressure steam, and the like, and that has good antireflection effect in the visible light range. In the contact lens 10 for vitreous surgery used to observe the ocular fundus 3 during vitreous surgery, an antireflection film 14 produced by ion beam sputtering is coated onto the upper surface 13 of a lens main body 11, and the antireflection film is a multilayered film in which a high refractive index layer 18 that contains tantalum pentoxide (Ta 2 O 5 ) and a low refractive index layer 19 that contains silicon dioxide (SiO 2 ) are alternatingly layered.
