These are the lens cleaning wipes that use nanotechnology to remove dirt, prevent fog, and restore a crystal-clear view to eyeglasses. The proprietary formula works at the molecular level by trapping dirt and oils and suspending them in solution above the surface, so gunk can easily be wiped away without scratching or damaging delicate coatings. The solution also leaves behind a temporary nano-coating that continues to protect against dust and fingerprints. Can also be used to clean goggles, camera lenses, and smartphone screens. Made in the U.S. 150 individually packed wipes.
