The privacy filter can be installed in two different ways. Affix the privacy shield to bezel-less displays using the transparent and residue-free adhesive strips. Alternatively, use the slide mount tabs to install the privacy screen on displays with bezels. The latter is recommended when frequent reversal or removal is required.Blue Light ReductionReduce eye strain and improve visual comfort with this blue light-reducing privacy shield. It blocks 40% - 51% of the blue light emitted from the display in the 380nm - 480nm wavelength range.
