Polycarbonate
lenses are up to 10 times more impact-resistant than plastic or glass lenses
and they provide 100% protection from the sun's harmful UV rays. They are also
lightweight, adding to the comfort of your eyeglasses, sunglasses, and sports
eyewear.
Polycarbonate
was introduced to consumers in the 1980s as a safe, affordable alternative to
standard plastic and glass eyeglasses. Today, polycarbonate lenses set the
standard in eyewear safety. These lenses are a smart choice for athletes, those
who work in hazardous job environments, and especially for children. Kids have
a greater tendency to drop their glasses and play a bit rough, so ideally all
children’s frames should have polycarbonate lenses. Polycarbonate lenses are
also ideal for people who wear rimless eyeglass frames, because they are less
likely to fracture than plastic or glass lenses.
Make
the Most of Your Polycarbonate Lenses
To
optimize the benefit of polycarbonate lenses, consider these complimentary
products:
Scratch
Resistant Coating: Polycarbonate is an impressive impact resistant lens.
However, part of the reason it’s so strong is because it’s, ironically, a
relatively ‘soft’ material. Being flexible is what enables it to absorb energy
without fracturing. But being a soft material requires a scratch-resistant
coating to prevent surface scratches. Once a scratch-resistant coating is
applied, your polycarbonate lenses will be nearly as hard as glass–yet remain
highly impact-resistant.
Proper
Frames: To ensure the safest eyewear at work and during sporting activities,
frames specifically designed for safety are strongly recommended; putting
polycarbonate lenses into frames not rated for use as safety glasses can
actually be dangerous. Your eye care professional can advise you which frames are
safety-rated and best suited for your lifestyle — at work and at home.
