Safety glasses 3M SecureFit 400 — blue mirrored lenses, wraparound protective eyewear

3M SecureFit 400 safety glasses feature a wraparound design with blue mirrored lenses that reduce glare while providing impact-resistant eye protection. The lightweight frame and integrated SecureFit technology distribute pressure across the temples, delivering a comfortable fit without the need for manual adjustment. These protective glasses are intended for industrial and workshop environments as well as outdoor tasks where eye protection and reduced glare are required.

Advantages

The wraparound lens offers extended coverage for peripheral vision and splash protection, while the mirrored coating reduces reflected light and improves visual comfort in bright conditions. Impact-resistant polycarbonate lenses provide reliable mechanical protection against flying debris. The SecureFit technology adapts to the wearer’s head shape to lower pressure points and improve stability during movement. The design is lightweight for all-day wear and compatible with many types of hearing protection and hard hats.

Suitable for

• Workshop and machine shop work where flying particles are present
• Outdoor tasks and construction work with bright sunlight or glare
• General industrial maintenance and assembly operations
• Laboratory and material handling tasks requiring eye splash or dust protection

Key specifications

• Lens type: blue mirrored, polycarbonate
• Frame style: wraparound, lightweight
• Protection: impact-resistant lenses providing mechanical hazard protection
• Fit system: integrated pressure-diffusing SecureFit technology (no manual adjustment required)
• Coverage: extended peripheral protection

How to use

Place the glasses over the ears and position the nose bridge so the lenses sit comfortably against the face and provide full coverage of the eye area. Ensure the temples rest securely without creating excessive pressure; SecureFit technology will adapt to the wearer’s head shape. Inspect lenses before each use for scratches, cracks or contamination and replace the glasses if the optical clarity or mechanical integrity is compromised. Clean lenses with a soft cloth and manufacturer-recommended cleaning solution to avoid damaging the mirrored coating.

Usage recommendations

Use these safety glasses in environments where impact protection and glare reduction are required. Do not use for protection against chemical splash without verifying chemical compatibility. Replace eyewear that shows visible damage or when coatings are worn. Store in a protective case when not in use to maintain lens condition and performance.
