The Spearfish has a flexible frame with vented temples, a TPR nose piece, and TPR temple ends. Designed to contour with the natural curvature of the head, the Spearfish maximizes all-day wearability and comfort. Reader style lenses feature a magnification diopter positioned at the bottom inside of the lens. This improves workplace safety by eliminating the need to switch between safety and reading glasses. The BH225115PFT also features a PFT lens. Thanks to its chemical and physical properties, Performance Fog Technology is a permanent coating that prevents the formation of condensation on the lenses by absorbing the humidity drops.\nEach dozen is packaged in a retail-ready box.
