What is BS EN 16642:2020?

BS EN 16642:2020 is a technical standard that provides guidelines for the design and performance requirements of safety eyewear. It specifically focuses on eye and face protection against various hazards in different work environments. This standard covers both prescription and non-prescription safety eyewear and aims to ensure the highest level of protection for workers.

Importance of Safety Eyewear

Safety eyewear plays a crucial role in preventing eye injuries in various industries, including construction, manufacturing, and healthcare. The eyes are incredibly vulnerable to debris, chemicals, radiation, and other potential hazards. Without proper protection, workers are at risk of sustaining serious and potentially irreversible eye damage.

BS EN 16642:2020 addresses this issue by establishing clear and comprehensive requirements for safety eyewear. These include impact resistance, optical clarity, protection against harmful radiation (such as UV or laser), and compatibility with other personal protective equipment (PPE). By adhering to these standards, employers can provide their workers with effective eye protection, minimizing the risk of accidents and preserving their long-term eye health.

Key Provisions of BS EN 16642:2020

BS EN 16642:2020 outlines several key provisions that manufacturers must meet when producing safety eyewear. These provisions cover various aspects of design, materials, and testing methods to ensure the highest level of protection and quality. Some of the important provisions include:

Minimum thickness requirements for lenses and frames to withstand impacts

Optical quality specifications, including visual distortion and chromatic aberration limits

Scratch resistance properties to maintain visual clarity

Requirements for proper fit, comfort, and adjustability of eyewear

Protective coatings for enhanced durability and performance

Guidelines on the use of prescription lenses in safety eyewear

Testing methods to evaluate optical, mechanical, and thermal properties


BS EN 16642:2020 serves as a vital tool in ensuring the safety and well-being of workers. By adhering to this technical standard, manufacturers can produce safety eyewear that meets rigorous performance requirements. Employers, in turn, can provide their employees with reliable eye protection, reducing the risk of work-related eye injuries. It is crucial for both employers and employees to understand and implement the guidelines outlined in BS EN 16642:2020 to create a safe working environment.
