Glass Welding Lenses Vs Polycarbonate Welding Lenses

By phillips-safety

In recent years, welding lenses have started to be made with polycarbonate in addition to the traditional glass lenses. What are their differences?

Welding Lenses: Glass vs. Polycarbonate Materials

Welding Lens Material

There are advantages to glass and polycarbonate welding lenses that make them different. Your personal preference will be what ultimately decides which material is best for you. One is not considered new and the other old. Glass, and polycarbonate both are excellent at providing protection.

If you’ve never compared glass and polycarbonate welding lenses, then you are about to find out some of the significant differences. Polycarbonate is generally not available in flat welding lens plates, so it’s not usually used in welding helmets, masks, or goggles, whereas glass is available in flat and curved lenses.

Polycarbonate is also cheaper and less likely to break if dropped, but glass is more scratch-resistant and offers higher optical quality.

If you’re deciding between glass and polycarbonate welding lenses, here’s what you need to know:

  • Glass welding lenses come as flat welding plates, flat lenses, and curved lenses, making them available in more frame styles and helmets.
  • Polycarbonate welding lenses are not produced in as many shades as glass, so your shade selection is better if you go with glass.
  • Glass welding lenses are, obviously, made of glass. Glass breaks. If you drop polycarbonate welding lenses, they will not break. Ever. Polycarbonate is amazingly impact-resistant and shatterproof.
  • Polycarbonate welding lenses scratch much easier than glass welding lenses do, meaning that the glass lenses will last much longer, provided you don’t drop them.
  • Glass welding lenses have extremely good optical quality; polycarbonate’s optical quality is significantly lower.
  • Welding glasses that cover your face perfectly will reduce injury.

Polycarbonate welding lenses are very inexpensive, making them more affordable than glass lenses.

There are positives and negatives to both welding lens materials, so your personal preference for lens traits should be the determining factor for your choice of material in welding safety eyewear.

Most people who have been using a certain welding lens material tend to stay with that material, except when it comes to clip-on flip-ups; those are usually purchased in polycarbonate. Clip-on welding lenses are usually used to augment current welding eyewear (make them darker) or to give light protection during light procedures.

      How many are you looking for we can make it but we would need a large commitment. They are not commonly made.
