**DIAMOND HARD LENS SCRATCH-PROTECTION SYSTEM
This system uses an advanced ion-beam deposition technology-
which applies a surface of amorphous (uncrystallized) Diamonds,
making the glass lenses* ten times more resistant to scratches.
These lenses are also hydrophobic, shedding water more easily.
This property reduces water spots and makes cleaning easier,
so your glasses are perfect for the beach or rain.
This technology, originally developed by NASA,
is exclusive to Bausch & Lomb sunglasses.
