I mainly use them while working in the workshop and I am positively surprised by their comfort. I often wear the safety glasses for several hours and here, nothing pinches or becomes uncomfortable. A big plus is that you don't have to constantly adjust them. For this price, it's really a great purchase.

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 the Cobalt Flash shade with a 2.2 mm thickness are crafted from polycarbonate, offering a combination of light weight and exceptional resistance to mechanical impacts. An Anti-Scratch coating is applied to the surface, providing superior protection against scratches. Due to this coating, the lenses maintain their performance and appearance even with frequent, demanding use.
Equipped with polarization, the lenses effectively minimize glare, greatly enhancing visual clarity. They also boost contrast and color saturation, reducing eye fatigue during extended exposure to bright light.
contoured frames, side shields
A full frame structure, crafted from recycled polycarbonate, forms the foundation of this model. Utilizing advanced manufacturing methods, the design achieves an optimal balance between light weight, rigidity, and resistance to mechanical impacts.
Side shields offer additional eye protection against dust, fine particles, and other airborne hazards, raising the safety standard in challenging conditions. Ergonomically profiled temple tips guarantee a secure and comfortable fit, minimizing movement on the face and boosting wearability during active use.
standards and certifications
- EN 166 - a European standard specifying the optical and mechanical protection requirements for eyewear such as glasses and goggles. Optical criteria cover aspects like light transmittance and diffusion, refractive accuracy, resistance to heat and UV radiation, corrosion, as well as ignition resistance. Mechanical protection refers to impact resistance against objects, categorized into four levels marked by the letters S, F, B, and A, with S representing the basic level of protection and A indicating the maximum.
- EN172 - a standard specifying the labeling, light transmission coefficients, and testing procedures for sun filters designed to reduce solar glare.
- CE - a designation showing that the product adheres to EU safety, health, and environmental protection requirements. The CE mark verifies that the manufacturer declares conformity with relevant EU standards and directives.

Anti-Scratch coating
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
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
EN172 European standard specifying markings and transmittance and corresponding test methods for sunscreens that protect against solar glare.
Filtr CAT.3
CAT.3 filter provides light transmittance of 8% to 18%, effectively protecting eyesight in intense sunlight conditions, ideal for summer and in the mountains.

Simply comfortable glasses. They stay well on the head, don't slip during movement, and you barely feel them even after a long time. The shading is just right, and they look normal, without a typical 'work' appearance. I am very satisfied with them.

Light, comfortable, and they fit well on the head. They don't press even during prolonged wear, and on top of that, they look pretty cool for safety glasses. The lenses are clear, don't distort anything, and overall, they are very comfortable to use. For this price, a really good purchase.

I chose this model for everyday use because I was looking for simple but durable glasses. The transparent frame looks aesthetically pleasing and is universal – it matches almost everything. The lenses provide great protection from the sun, and even after wearing them for a long time, they don't tire my eyes, whether I'm driving or spending time outdoors. The material is solid, the glasses are well made, nothing creaks or loosens. They fit well, don't slip even when I bend down. Sturdy, practical glasses at an attractive price.
