Product Information

Full details

The Bolle Safety STKS 420 Safety Glasses are designed for professionals and active individuals who require reliable eye protection without sacrificing comfort or style. Featuring a modern, athletic aesthetic and an eco-friendly build, these glasses provide exceptional glare reduction and optical clarity for outdoor work environments; however, the fixed smoke tint makes them unsuitable for use in low-light or indoor settings.

Extended Product Information

FAQs

Are these glasses suitable for indoor work?

No. The smoke lens has a 13% light transmission, which is too dark for indoor use and may compromise your visibility.

Can I replace the lenses?

No, the STKS 420 features a fixed lens design and the lenses are not intended to be removed or replaced.

What does the Platinum coating do?

The Platinum coating is a specialized treatment that provides high-level resistance against both fogging and scratching.

Do these glasses provide UV protection?

Yes, like all high-quality Bolle safety eyewear, these are designed to provide protection against harmful UV radiation.

Are these glasses ANSI rated?

These glasses are certified to the EN ISO 16321-1 standard, which is the international equivalent for high-quality industrial safety eyewear.

Troubleshooting

Lens appears smudged or blurry

Clean the lenses using only a clean, dry microfiber cloth or authorized lens cleaning solution; avoid paper towels which can cause micro-scratches.

Fogging occurs during extreme use

Ensure the Platinum coating is clean. If fogging persists, wipe with a clean cloth to activate the anti-fog properties and ensure proper airflow around the eyes.

Setup, Compatibility & Care

To ensure the longevity of your Bolle STKS 420 safety glasses, follow these maintenance guidelines:

  1. Cleaning: Use a microfiber cloth and, if necessary, mild soapy water. Avoid using harsh chemical solvents, as these can degrade the protective coatings.
  2. Storage: Always store the glasses in a protective case when not in use to prevent deep scratches on the lens surface.
  3. Inspection: Before each use, inspect the frame and lenses for structural damage. If the lens is deeply scratched or the frame is cracked, the glasses should be replaced to ensure continued safety compliance.
  4. Compatibility: These glasses are designed for a standard fit. They are compatible with most standard hard hats, though user fit may vary depending on the helmet suspension system.
