The benefits
As uncoated plastic lenses are not as hard as glass lenses, they need a hard coating to give them added resistance to scratches. A hard coating will increase the lifetime of your plastic lenses.
Product info
Different technologies can be used to apply hard coatings. Two possibilities are ion-assisted vacuum deposition and the dip lacquer technique.
