The primary reason Hasbro has introduced the new N1 dart for its Nerf N-Series lineup is to create a safer and softer dart that can be fired at higher speeds without increasing the dart's weight or impact on a child1. The new N1 dart is shorter, wider, and squishier, allowing it to be fired at 90 feet per second compared to the 70 feet per second of the Elite darts they're replacing16. This change in dart design is also aimed at maintaining the integrity of the Nerf brand by guaranteeing a certain level of safety.

The proprietary nub on the new N1 darts is a safety feature designed to ensure that only official Nerf N1 darts are used with Hasbro blasters. This feature maintains the integrity of the Nerf brand by guaranteeing a certain level of safety when the darts are fired at their intended speed of 90 feet per second. By having a wider and shorter design, the N1 darts can be softer and safer, reducing the risk of injuries during play. The use of the patented nub allows the blasters to recognize and only fire official Nerf darts, preventing the use of potentially harmful third-party darts. As a result, Hasbro does not ship safety glasses with these blasters, as the safety of the darts is built into their design.

Hasbro has decided not to include safety glasses with the new N-Series blasters because the new N1 darts are designed to be wider and shorter, making them softer and safer. The proprietary nub on the N1 darts is meant to maintain the integrity of the Nerf brand by guaranteeing a certain amount of safety at the higher speed. As a result, Hasbro believes that safety glasses are not necessary for these blasters.
