Looking to renew my safety glasses and bemused by complexity of classification and price ranges.
But to pick on one quality, the F (low energy impact rating - small object impacts at up to 45m/sec) or B (medium energy impact rating - small object impacts at up to 120m/sec), which should one choose?
Thanks.
