Outstanding product. These glasses feel like high quality.I have the normal Dewalt safety glasses and was swapping my readers in and out. Having these with bifocal lenses has made life a lot easier. I spend a lot of time in various factories and often struggle to see up close. These made my work a lot easier. The glasses are comfortable too. Purchased them because they are the same style of a pair of okleys I already own. Love how easy is to replace the lenses, the lenses quality and the light weight and fit of the frame. But with the light weight I must also talk about the quality of the material. Nothing like the okleys that I’ve already have had for over 5 yrs. maybe me comparing apples to orange but because it seem flimpsy I gave them to my BF.
