Abstract: A polymerizable liquid composition including semi-conductive nanoparticles for the manufacture of ophthalmic lenses. Specifically, polymerizable composition has at least one monomer or oligomer; at least one catalyst for initiating the polymerization of the monomer or oligomer; and semi-conductive nanoparticles, which are dispersed in the monomer or oligomer. The absorbance through a 2-millimeter-thick layer of the polymerizable composition is higher than 0.5 for each light wavelength ranging from 350 to ?cut, ?cut being in the visible range, preferably in the range from 400 nm to 480 nm.

Abstract: A light filtering glass container including a glass container coated with a light filtering coating obtained by curing a polymerizable composition including semi-conductive nanoparticles. The absorbance through a 5-micrometer thick light filtering coating is greater than 0.5 for each light wavelength ranging from 350 nm to ?cut, ?cut being in the range from 420 nm to 480 nm, and the difference of lightness between the uncoated glass container and the glass container with the light filtering coating is lower than 5.

Abstract: A display that includes an image producing system and a light filtering layer in the blue range, the light filtering layer having a limited impact on the gamut of the display. The image producing system has a gamut G0 defined in a color space The light filtering layer includes semi-conductive nanoparticles, and the absorbance through the light filtering layer is greater than 0.25 for each light wavelength ranging from 350 nm to ?cut, ?cut being in the range from 420 nm to 450 nm. The gamut G1 of the image producing system with the filtering layer has an area greater than 90% of the area of gamut G0 in the color space.
