The Top 3 Brands of CSA-Approved Safety Glasses

Choosing CSA safety glasses is mostly about two things: verified certification and day-to-day comfort. The three brands we've selected to cover are models that meet CSA Z94.3 approved specifications.

We advise that you always confirm the mark on the specific frame or lens because not every model in a particular line carries the same approvals.

Milwaukee

Who is Milwaukee?

Milwaukee is best known for power tools, but their PPE line has grown steadily since 2019. They've added lens colours, anti-fog options, and tougher coatings.

The standout tech of their safety glasses

• Fog-resistant lenses designed for humid, high-sweat work.
• Hard-coat lenses to better resist scratches.
• "Performance" models rated above ANSI Z87.1+ with high-velocity impact claims (tested around 725 fps).
• Select styles have arc-flash testing (ASTM F2621) with no ignition/melting at stated cal/cm² exposures (model-dependent).

Why people pick them

Solid impact protection, lots of lens tints for indoor/outdoor work, and comfortable touch points (flexible nose bridge and temples) that make all-day wear easier.

Keep in mind that higher-spec models cost more and that even good anti-fog can struggle in extreme conditions, and hard coats improve but don't eliminate scratching, especially with dust or grit.

Uvex

Who is Uvex?

A German brand with roots in optical protection since 1926; "uvex" comes from "ultraviolet excluded." They're widely respected for lens materials and coatings.

Standout tech of Uvex safety glasses

• Well-engineered anti-fog and scratch-resistant finishes.
• Broad specialty range, including prescription and laser-rated eyewear.
• Strong focus on precise fit and long-wear comfort.

Why people pick them

History, consistent optical quality, and a deep catalogue for specific environments (lighting, dust, laser work, and more).

Remember, premium engineering often means a higher price and advanced coatings still wear over time.

Availability for certain models can vary by region. Just double-check CSA Z94.3 on the exact model if you're buying for Canadian workplaces.

3M

Who is 3M?

3M is a long-standing PPE player with one of the widest eyewear ranges - from basic shop glasses to feature-rich industrial models.

Standout tech of 3M safety glasses

• ANSI Z87.1 impact protection across most lines, with many high-impact variants.
• Polycarbonate lenses that block 99.9% UVA/UVB on many models.
• Multiple coatings, including Scotchgard™ anti-fog that's engineered to resist fogging longer while keeping abrasion resistance.
• SecureFit temples that diffuse pressure for a more even, comfortable hold, optional foam gaskets on select models for dust.

Why people pick them

Huge selection, predictable quality, and easy to find and often with CSA-marked options for Canada.

Also note that coatings wear with heavy use or chemical exposure and the right fit can be model-specific. What works for one head shape may not for another. Added features raise the price and may add upkeep.

Quick Checklist for Choosing the Right Pair

Listen to a brief discussion on the Top Features of Milwaukee, 3M and Uvex CSA Safety Glasses:

Look for the mark

Ensure CSA Z94.3 is stamped/printed on the eyewear you're actually buying.

Match the environment

Humidity/temperature swings: anti-fog coatings or vented designs.

Dusty work

Models with foam gaskets (and a cleaning routine).

Glare/lighting

Choose tints (grey/outdoor, amber/contrast) to suit the task.

Prioritize fit and comfort

Try them on. Check nose bridge comfort, temple pressure, and whether the frame stays put without pinching.

Plan for wear

Coatings extend life but don't last forever. Budget for replacement or rotate two pairs if abrasion is common.

Care and storage

Rinse grit off before wiping, use a microfiber cloth, and store in a case to protect coatings.

In Summary

• Milwaukee: Robust, job-site-ready options with higher-spec choices for impact and arc environments.
• Uvex: Precision optics and coatings with strong comfort and specialty lines. Great if you need a tailored solution.
• 3M: Broad availability and feature sets at many price points including advanced anti-fog and comfort-focused designs.

Pick a pair that shows CSA Z94.3, fits your face, and matches the conditions you work in. That's what keeps eyes safe and glasses on.
