The Oleophobic and Hydrophobic treatments are essential to guarantee the durability of the lens.
Oleophobic treatment involves applying multiple layers of coating to the surface of the lens that repel dust and grime from the lens, making it easier to clean your lenses and to avoid the risk of ruining them.
Hydrophobic treatment involves applying one or more coatings that repel water and other liquids from the surface of the lens.
These coatings make it easier to clean your lenses because of the smoother, anti-static surface they create.
Oleophobic and hydrophobic coatings also keep lenses visibly cleaner to improve vision.
