Every material object exposed to the environment, including bino and scope lenses, are coated with a microscopic oil residue, the unfortunate by-product of environmental pollution. This lens clean-er is the first one designed to remove this oil residue. In a National Bureau of Standards test, ROR increased optical resolution 40% over cleaning with standard lens cleaners. Used by NASA as an integral part of space flights, and by such optics manufacturers as Leica, Hasselblad, and Bausch & Lomb. Two-ounce spray bottle.
