- add a note asking them to consider using a higher index lens material.
eg polycarbonate=impact/stress resistance and is available in Transitions.
If they have used such, they should not have "shattered", unless of course, you've had a pretty severe accident. Worth asking the question though.
The most common lens material is a hard resin and should never be used in 3 piece rimless frames.
