All of our lenses (
especially the high index packages) are of
high
quality,
But misusing them or dropping them too many times may still result in breakage.
Please note - some frames are more durable then others and protect the lenses more - Plastic are
more durable then Rimless for example
We also have our safety category -
Safety
Category
That are designed to uphold high standards of durability (ANSI Z87)
However , these safety frames and lenses , as durable as they may be,
Are not completely break proof, if exposed to extreme conditions.
