Which of the following is NOT a special feature of approved safety glasses?

Approved safety glasses are designed with specific features to protect the wearer from potential hazards in various environments. The features that are typically associated with safety glasses include front and side protection, which helps shield the eyes from debris and impacts coming from different angles. They are also lightweight and durable to ensure comfort during long periods of use while maintaining resilience against breakage.

Anti-fog and anti-scratch coatings are also common features of safety glasses, enhancing visibility and prolonging the life of the lenses by reducing scratches and preventing fogging from temperature changes or humidity.

While adjustable nose pads can be beneficial for comfort and fit in many types of eyewear, they are not an inherent feature of all approved safety glasses. The priority for safety glasses is ensuring robust front and side protection as well as durability and visibility enhancements, rather than customizability in fitting. Therefore, adjustable nose pads do not classify as a standard or essential feature of approved safety glasses.
