This is as effective as wetting lenses, but much faster: our ZEISS lens cleaning spray is perfect for thorough cleaning. Apply the spray to a microfiber cloth, not to the lenses themselves. Did you know... rimless frame lenses have drilled holes, while standard frame lenses have screw holes? If moisture gets into the screw holes, it can eventually damage your lenses. Therefore, you should apply the spray on a microfiber cloth and not on the lenses themselves. Then, wipe with enough moisture to effectively remove dirt, makeup and oil, without damaging the lenses.
