Ess crossbow 2x - ESS Crossbow 2X Eyeshields - Two Pairs Crossbow Frames Clear/Smoke Lenses

I use these every day for safety glasses as a pressure welder in the oil and gas industry in Alberta, Canada
The versatility of the interchangeable lenses is fantastic for different lighting applications and quick change options.
Althoughthe greatest feature I find, is the optically correct view one gets looking through these lenses, it is always clean and crisp. This is essential for accuracy in my line of work.
