They certainly look a bit weird, but they work! No more fogged-up safety glasses. The SN-1000 Bugz-Eye Sight Shields protect against debris, foreign particles, wood chips, and other similar materials. Arborists, stump grinders, loggers, and other chainsaw operators highly prefer these goggles. Bugz-Eye features an anti-fog steel 20-mesh that provides clear visibility. An anatomically designed polycarbonate frame perfectly fits the facial bone structure, and open-cell foam enhances comfort and seal. However, it is essential to note that these goggles, like all mesh eye-protective products, do not provide complete eye protection and are unsuitable for stopping large or heavy flying objects.
