Uvex XC Safety Glasses with Black Frame and Reflect 50 Lensstar rating 5paul williamsDecember 10, 2010I started using these with my perscrition as an issued item in Iraq. Since my return, I had broken my old pair and needed a new set. I came back to these because of the unique option of putting a pair of perscrition inserts in. I hate wearing side shields because of the limited perifrial vision, but these glasses with the inserts opens up the side vision and protects my eyes. I love them!!
