## Summary description

3M SF420AF safety glasses with a plastic frame and transparent polycarbonate lenses. Designed for assembly, construction/renovation and grinding work, these protective goggles offer impact-resistant eye protection for any gender. The black frame provides a neutral appearance while polycarbonate lenses deliver clarity and durability for industrial and DIY tasks.

## Long description

3M SF420AF safety glasses feature a lightweight plastic frame and clear polycarbonate lenses with an anti-fog coating and a built-in +2.0 reading diopter. The lenses absorb 99.9% of UVA and UVB radiation up to 380 nm and are impact resistant, meeting CSA Z94.3-2007 and ANSI Z87.1-2010 requirements. The SecureFit design uses Pressure Diffusion Temple Technology to let the temples naturally adapt to individual head shapes for a secure, comfortable fit suitable for industrial and DIY tasks such as assembly, construction/renovation, and grinding.
Advantages
The SF420AF combines lightweight construction (less than 1 ounce) with flexible temples that self-adjust without manual settings, reducing the need to stock multiple frame sizes. Anti-fog coating maintains visibility in hot or humid conditions, while polycarbonate lenses offer impact resistance and block nearly all UV radiation. A +2.0 reading diopter helps with close-up detail work and reading small print without adding separate reading lenses.
Suitable for
Assembly and manufacturing tasks
Construction, renovation and on-site maintenance
Grinding, sanding and similar detail work
DIY projects and general workshop use
Situations requiring lightweight, impact-resistant eye protection with reading aid
When it may not be suitable
These glasses are not prescription eyewear; users who require specific corrective prescriptions should use prescription safety glasses or insert prescription lenses. They may not provide optimal protection for chemical splashes or environments requiring sealed goggles or full-face protection.

How to use
Place the glasses on so the temples rest comfortably over the ears; the Pressure Diffusion Temple Technology will allow the temples to conform to the wearer’s head for a secure fit. Clean lenses with a soft, lint-free cloth and manufacturer-recommended cleaner; avoid abrasive materials that can damage coatings. Use the anti-fog properties by keeping lenses free of heavy dirt or oils that reduce coating effectiveness. Inspect the glasses before use and replace them if lenses are scratched or the frame is damaged.
What to consider before purchase
Whether you need prescription correction in addition to the built-in +2.0 diopter
Whether your work requires sealed eye protection against liquids or chemicals
Compatibility with other personal protective equipment, such as helmets or hearing protection
Preferred lens treatments (anti-scratch, anti-fog, Scotchgard Protector)
Usage recommendations
For reliable performance, choose the SF420AF when you need lightweight impact protection with a reading aid. Store the glasses in a protective case when not in use, clean lenses regularly with non-abrasive cleaner, and replace the eyewear if impact damage or deep scratches occur.
