Oil stain resisting film for lens

Abstract

The invention discloses an oil stain resisting film for a lens. The oil stain resisting film is arranged on each of two surfaces of the lens. The oil stain resisting film comprises the following components in percent by weight: 60-80 percent of magnesium fluoride and 20-40 percent of zirconium oxide. By using the magnesium fluoride in the oil stain resisting film disclosed by the invention, oil stain and water can not be difficultly adhered onto the lens and can be easily wiped even if being adhered onto the lens, so that the light transmittance of the lens is increased, and the use effect is added. In addition, due to the addition of the zirconium oxide, the wear resistance of the oil stain resisting film can be improved, the lens can be prevented from being scraped due to excessive wiping, and the service life of the lens is prolonged.
