Ergodyne Skullerz Thor Anti-Fog Safety Glasses — Z87.1+

Reading the Z87 marking, and what it does not cover

Protective eyewear in the US is built to ANSI/ISEA Z87.1, and OSHA 1910.133 requires eye protection that meets it. The marking on the frame is the specification, and the important distinction is a single character: Z87 is basic impact, Z87+ is high impact — tested with a quarter-inch steel ball at 150 ft/s for spectacles. If the work throws anything, Z87+ is the line.

The suffixes narrow it further: D3 is splash and droplet, D4 dust, D5 fine dust. These matter because a spectacle cannot earn D3 — droplet protection needs a sealed goggle. Safety glasses are impact protection, not chemical splash protection, however wraparound the lens looks, and substituting one for the other is a common and consequential error.

A face shield is also secondary protection under 1910.133: it is worn over primary eye protection, never instead of it. And tint is not shade — a dark lens without a stated IR/UV shade number offers no rated protection against radiant energy.

Frequently asked questions

What is the Ergodyne Skullerz Thor?

An ANSI Z87.1+ safety glass with a permanent anti-fog lens coating, engineered for work where temperature transitions, humidity, and exertion fog conventional glasses. It is offered in clear, indoor/outdoor, and smoke tints.

What does Z87.1+ mean?

Z87.1+ is the high-impact rating under ANSI/ISEA Z87.1, meaning the lens passes the high-mass and high-velocity impact tests required for regulated industrial and construction eye protection, as the listing states.

How is the anti-fog different from a spray?

The Thor uses a permanent bonded anti-fog lens coating rather than a temporary spray, so it maintains clarity through temperature differentials and sweat without wiping off during the shift.

Are these chemical splash goggles?

No - the Thor is an open safety glass, not a sealed goggle. For a chemical splash hazard, use D3-rated splash goggles or a face shield over your primary eyewear.

Where does anti-fog matter most?

The listing points to food-processing cold rooms, welding and hot-work areas, humid outdoor construction, and any environment where fogged lenses cause workers to remove their eye protection and break compliance.

What lens tints are available?

The listing lists clear (51003), indoor/outdoor (51083), and smoke (51033), all on a black frame - confirm the variant you need.

Which tint should I choose?

Clear for indoor and low-light, indoor/outdoor for transitional work, and smoke for bright sun. The lens comparison guides cover the trade-offs.

Why do workers remove fogged glasses?

Fogged lenses impair the ability to see the task, so workers lift or remove them - a documented compliance and productivity failure that a durable anti-fog coating is designed to prevent.

Does it fit a range of faces?

The Skullerz styling is designed to be accepted by workers who resist standard safety glasses; confirm the fit and any size options on the product listing.

What sizes are available?

Confirm the fit options on the product listing; a properly fitted frame keeps the lens positioned for its rated coverage.

How do I care for them?

Clean with lens-safe wipes to preserve the anti-fog coating, avoid abrasive cloths, and retire the glasses when the lens is scratched enough to impair vision, since damaged eyewear no longer protects as rated.

How do I order for a crew?
