ABSTRACT:
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 lens10for vitreous surgery used to observe the ocular fundus3during vitreous surgery, an antireflection film14produced by ion beam sputtering is coated onto the upper surface13of a lens main body11, and the antireflection film is a multilayered film in which a high refractive index layer18that contains tantalum pentoxide (Ta2O5) and a low refractive index layer19that contains silicon dioxide (SiO2) are alternatingly layered.
