Ophthalmic devices having a highly selective violet light transmissive filter and related methods

Ophthalmic devices are provided having a violet-light vertical cut-off filter abruptly absorbs light between the wave lengths of between approximately and 400 nm and 450 nm such that a curve when plotted as percent transmission versus wavelength has the shape as depicted in FIG. 2. In one embodiment...

More Information
Summary:Ophthalmic devices are provided having a violet-light vertical cut-off filter abruptly absorbs light between the wave lengths of between approximately and 400 nm and 450 nm such that a curve when plotted as percent transmission versus wavelength has the shape as depicted in FIG. 2. In one embodiment the ophthalmic devices are made from acrylates and the light absorbing compound is an Eastman Yellow 035 MA dye.
