Eye protection is critical in metal fabrication environments. Welding, UV radiation, dust, flying metal fragments and splashing chemicals are all hazards that can affect the eyes. Any one of these hazards can permanently damage the eyes, leading to reduced vision or blindness.
Of course, not all eye protection is created equal. We’ve come a long way from the days when workers sported glass eyewear styles and simple looking goggles. For those workers who need PPE to survive real-world conditions, MCR Safety has you covered on multiple levels.
Scratch Resistant Technology
While garments, gloves and boots can remain functional, even with some scuffs or scratches, a small scratch on a safety glass can lead to visual distraction and drastically reduce visibility. Since the intent of protective eyewear is keeping your eyes safe, it is imperative the glasses do not scratch.
In a 2013 eyewear survey conducted, 59% of all surveyed listed scratch resistance as the #2 most important buying decision when selecting safety glasses. A little over a year later, Max 3 technology was introduced, offering wearers 3X greater scratch resistance. Now, over 15 styles incorporate this technology.
MAX3 scratch-resistant glasses can stand up in the harshest working environments you are likely to meet on the job - MAX3 in action. We do not recommend rubbing your face with steel wool, but if you did, your glasses with MAX3 scratch-resistant technology would come out looking brand-new.
In the same survey mentioned above, 60% of all surveyed listed fogging as the #1 most important buying decision when selecting safety glasses. Fog is not going to hurt your eyes, but it will hurt your visibility, which can cause serious accidents and injuries. In an industry where machine shop and metalworkers are going in and out all day to retrieve materials, fogged glasses are a real concern.
There are a couple reasons why glasses fog:
- Quick-rising temperatures (as when walking into a heated building on a snowy day)
- Humid air being aimed directly at glasses, as when wearing a mask or respirator, are two common examples.
The solution many people use is anti-fog wipes, like our LFT Fog Buster. The only downside to these is that your glasses need reapplied every time your glasses fog up. This is a perfectly respectable solution … once or twice. But if you’re regularly encountering major differences in temperature or wearing a respirator on a daily basis, it’s not a long-term fix. Moreover, if you are responsible for a number of people, multiply the several minutes it takes to de-fog glasses by the number of times it occurs by the number of employees, and you are losing a significant amount of productivity, even if nobody gets hurt when they are unable to see. And that’s a big if.
Enter anti-fog technology. Originally developed by NASA during Project Gemini to keep space suit visors fog-free (and it’s hard to imagine any climate more demanding than the vacuum of space), anti-fog agents prevent condensation from forming.
Anti-fog coatings work to various degrees, and our MAX6 technology is some of the best, offering six times the anti-fog performance of standard fog-resistant styles. Where standard glasses can take minutes to clear and anti-fog glasses can take 60 seconds or more, glasses with MAX6 technology clear in 10 seconds or less, when they fog up at all. Max 6 technology is incorporated into the lens during manufacturing, so no need in worrying if the coating needs reapplied!
Who would every think up a technology with both Max 3 and Max 6? You guessed it; we take innovation rather seriously, definitely when it involves the safety and wellbeing of today’s modern worker.
MAX36™ lenses are flow coated, also known as "dual coated" lenses in which we apply our MAX3™ to the outside lens and then MAX6™ to the inside lens. Imagine having the toughest, durable safety glasses yet not having to worry about them fogging up while on the job site. MAX36™ does just that! MAX3™ protects the outside of the lens from flying metal, debris impact and scratches while MAX6™ ensures fog free visibility. If your job does not require you to move from one extreme temperature to another then MAX36™ is just the coating you need.

When you combine MAX3 anti-scratch technology and MAX6 anti-fog technology in MAX36 glasses, you have a pair of glasses designed for the most challenging and rugged working environment.
Most people associate polarized lenses with sunglasses, which are primarily designed to protect your eyes from UV radiation. Since most sunglasses are polarized, it makes sense that people associate polarization with UV protection. But as it turns out, the UV protection from polarized glasses is about the same as standard sunglasses. So why bother with polarization?
In the end, this comes down to visibility. Standard sunglasses filter out UV rays by allowing less light to come through in general. Polarized glasses take a different route, one that takes advantage of our modern understanding of the physics of light.
Rays of light are three-dimensional, vibrating in all directions. When light is aligned in one particular direction, it’s said to be polarized. Aside from light coming directly from the sun, most of the light we see is polarized when it bounces off horizontal surfaces. The light reflecting off the surface of a lake, a highway, or a field of snow is all horizontally polarized. Polarized glasses take advantage of this, and only allow light that is vertically oriented. Like trying to force a button through a butttonhole the wrong way, horizontal light is reflected back into the world instead of your eyes. This means less UV light damaging your vision, but also less glare from all those horizontal surfaces.
If you want to test this for yourself, you can. Hold a pair of polarized glasses in front of you and view a road or parking lot through them. Slowly rotate the glasses so that you’re holding them vertically, with one lens on top of the other instead of side by side. You’ll see a significant increase in glare when you do. If you don’t see a change, you may have purchased knockoff “polarized” glasses from a less reputable source. Only trust the best with your eyesight!
MAX3 + MAX6 + Polarized
Would the MCR Safety R&D team even entertain a wild idea of merging all three technologies into one style? The answer is absolutely yes, see for yourself! Four styles incorporate all three technologies, creating the ultimate safety glass.
Metal Fabrication Industry Safety Hazards
Gloves and garments are great, but they’re the second line of defense at best when it comes to workplace hazards. The first is your sight. Being able to see trouble before it hits is the biggest factor in onsite safety, so don’t settle for less than the best.
Over the next six months, MCR Safety will be highlighting all the safety hazards facing metalworkers and the Metal Fabrication. Click on the below image and see the metalworking PPE solutions offered.
