System and method for selective light inhibition
First Claim
1. An ophthalmic system comprising a film containing a dye that selectively inhibits light having a wavelength of 400 nm-460 nm;
- the film is interspaced between two ophthalmic lens layers; and
wherein the system has a photopic luminous transmission of at least 85% across the visible spectrum and a phototoxicity ratio less than about 80%.

Abstract
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.
