The Dräger X-pect 8330 goggles is made of plastic, or polycarbonate, anti-scratch and anti-fog and provides UV protection. Who is wearing glasses, the glasses is not really suitable, unless you climb onto contact lenses to. For eyeglass wearers, there are also other variants, which are much larger and completely closed. I ordered my glasses because I have to cut hedges and shrubs. For this purpose, it is well suited. Even if you stand on the circular saw in the shop, nothing without safety goggles. The product is high tiptop sitting properly. I already had glasses for 3-5 Euro. These scratch quickly and can be discarded after one pass most. Therefore, one should grab befitting a high end product of a brand manufacturer, such as Dräger or UVEX. 3M I leave now rather fingers because 3M has hardly anything produced in America and extremely diminished quality.
