Polycarbonate, also known as poly,
was invented by the aerospace industry for gear used on
the Apollo space shuttle (helmet visors etc.). It is an
impact resistant material that is highly recommended for
rimless, safety glasses and sports eyewear. Poly is
known for its resistance to chipping or shattering and is 40 times more resistant than
FDA requirements. However, once polycarbonate is
severely scratched it may loose its impact resistance qualities.

Poly is a flexible material that
needs a hard coat to protect it from easily scratching,
but also has a natural UV protective nature. However,
some patients may be hyper sensitive to the “chromatic
aberration” poly has when using the peripheral viewing
area leading to afish bowl effect. |
