The markings on spectacles, goggles, and visors are required by EN 166, the European standard for personal eye protection, as well as other relevant standards. These markings provide important information about the properties and fields of use for each eye protection product.
The markings must be presented in a specific order and position on the product. Key elements of these markings include:
Frame/Body Marking: Indicates the type of eye protection (e.g. spectacles, goggles).
Impact Resistance: A letter such as F, B, or A shows the level of impact resistance. F is for low-energy impact (up to 45 m/s), B for medium-energy (up to 120 m/s), and A for high-energy impact (up to 190 m/s).
Optical Class: Numbered 1, 2, or 3, this denotes the lens quality and whether it is suitable for continuous use (1) or short-term use (2 or 3).
UV Protection: A marking such as ‘2C-’ or ‘5-’ indicates the UV filter level, ensuring protection against harmful ultraviolet radiation.
Scratch Resistance: Lenses marked with ‘K’ indicate they are resistant to surface damage from fine particles.
Anti-Fog: Marked with ‘N’, indicating resistance to fogging.
Additional Information: Any other relevant information about coatings or specific protective features.
These markings allow you to easily determine the suitability of a product for your specific needs, ensuring compliance with safety standards and maximum protection.
Summary of key points:
- Markings on eyewear products follow EN 166 and other relevant standards.
- Impact resistance, optical class, and UV protection are key properties.
- ‘K’ indicates scratch resistance and ‘N’ indicates anti-fog protection.
