Bolle STKS 420 Glasses - Crystal/Cobalt Flash Polarized
Engineered for individuals working in harsh field environments, these glasses offer both reliable eye protection and exceptional user comfort. Featuring a robust build and top-grade polarized lenses equipped with a CAT.3 filter, they safeguard eyes from intense sunlight by minimizing glare and enhancing contrast.
Protection is ensured against debris, ricochets, and other projectiles in accordance with Class F standards (objects weighing 0.86 g at velocities of 45 m/s).
polarized visors with anti-scratch coating
Lenses in Cobalt Flash color and 2.2 mm thickness are made from polycarbonate, which combines low weight with high resistance to mechanical damage. An Anti-Scratch coating is applied to their surface, enhancing scratch resistance. Thanks to this coating, the glasses will retain their properties for longer, even with intensive use.
Thanks to the use of polarization, the lenses reduce glare, significantly improving image clarity. Additionally, they enhance contrast and color saturation, reducing eye strain during prolonged use in intense light.
contoured frames, side shields
The model is equipped with a full frame type full frame, made from recycled polycarbonate. The application of modern production processes allowed for a design that combines light weight with appropriate rigidity and resistance to mechanical damage.
Side shields protect the eyes from small particles, dust, and other contaminants, increasing the level of protection in demanding environments. Ergonomically contoured temple tips ensure a stable and comfortable fit to the face, reducing the risk of shifting during movement and enhancing wearing comfort.
standards and certifications
- EN 166 - a European standard regarding optical and mechanical protection requirements for glasses and goggles. Optical requirements include light transmission and diffusion, refractive properties, resistance to heat and UV radiation, corrosion, and ignition. Mechanical protection involves impact resistance of objects, with four levels denoted by letters: S, F, B, and A, where S is the lowest level of protection and A is the highest.
- EN172 - a standard defining markings and transmission coefficients as well as appropriate test methods for sun filters protecting against solar glare.
- CE - a marking that indicates the product meets the requirements of EU standards and regulations concerning safety, health, and environmental protection. The CE marking confirms that the manufacturer certifies the conformity of their product with relevant EU standards and directives.

Anti-Scratch coating increases the scratch resistance of the lenses and protects them from mechanical damage. Thanks to the coating, the glasses will retain their properties for longer, even with intensive use.
EN166 is a European standard for optical requirements and mechanical protection for glasses and goggles. Optical requirements include light transmission and diffusion, refractive properties, heat and UV resistance, corrosion and ignition. Mechanical protection is the resistance to object impact, within which there are 4 levels designated by the letters S, F, B and A, where S is the least protection and A is the highest.
EN172 European standard specifying markings and transmittance and corresponding test methods for sunscreens that protect against solar glare.
