A film suitable for use in an ophthalmic system is provided. The film may
selectively inhibit blue light within the wavelength range of 400 nm to
460 nm to reduce phototoxic light to the eye while maintaining photopic
vision, and may be color balanced to allow for the system into which the
film is incorporated to be perceived as colorless to a viewer observing
and/or using the system. The system may have a photopic and scotopic
luminous transmission of 85% or more and a phototoxicity ratio of less
than 80%. When used in an ophthalmic system or other system disposed
between an observer's eye and a light source, the film may reduce the
flux of blue light to the internal structures of the eye while reducing
or minimizing dilation of the pupil.
