CR39 lenses are chemically treated with a hard scratch-resistant coating which provides extra protection during the lifetime of the lens. Please note that no chemical coating on a lens can be 100% scratchproof so be aware of any products that advertise the same.
This feature will be shown at London Eyewear with the following icon:
