It will affect non-magical compound weapons only if they are thrown. It may not be used in conjunction with magical ammo, even if fired from a non-magical weapon. Thrown alchemical weapons are considered non-magical and are compatible with this item.

A rogue wearing these lenses may sneak attack while wielding a bow or crossbow, but not any other Ranged weapon. An assassin (rogue sub-class) wearing these lenses may perform an assassination while wielding a bow or crossbow, but not any other Ranged weapon.
