Nikon Fog Klear

The Fog Klear lens cleaning cloth from Nikon is a soft microfiber cloth impregnated with an anti-fog compound that inhibits fog from clouding your lens, binoculars or viewfinder. The cloth works by leaving a microscopic film of the compound on your optic, lens or other surface which prevents the build-up of condensation. This cloth also removes surface particles and fingerprints which can spoil your vision.
