Polycarbonate Lenses
High-Tech Lenses for the Digital Age
Polycarbonate lenses are the most-used alternative material for modern
ophthalmic lenses.
Consumer interest in thinner, more attractive spectacle lenses led to the
development of special lens materials that would bend light differently than
conventional plastic lenses. These materials are called
"hi-index".
Among the high index materials developed for eyeglasses is one material that
has a number of very unique properties and that also provides special benefits
to eyeglass wearers. It carries the generic name "polycarbonate" but is sometimes
called something different by other manufacturer trade names.
- Great for sports protective eyewear
- A "must" for kids
- Comes with FREE Scratch and UV Protection
Impact Resistant - Polycarbonate Surpass AR lenses are 10 times more impact
resistant than plastic lenses.
Lighter - Polycarbonate Surpass AR lenses are up to 35% lighter and thinner than
standard plastic lenses for greater comfort.
UV Protection - Polycarbonate Surpass AR lenses shield your eyes from virtually
100% of the sun's harmful UV rays.
Scratch Resistant - PolyCarbonate Surpass AR lenses are hardcoated
for excellent durability and scratch resistance.
Easy Care - PENTAX EasyClean™ treatment resists dust and smudges,
making your Polycarbonate Surpass AR lenses easy to clean.
Polycarbonate was the first plastic high index lens and still has one of the
highest index ratings (1.59). High index advantages are included with every
polycarbonate lens so there is never any extra charge for high index when
polycarbonate lenses are ordered. Originally used primarily for industrial
safety glasses, now used for children, sports wearers, or anyone requesting
greater impact resistance in their lenses.
