The special NK coating on the Air Flow Safety Spectacle enhances the lens to have anti-scratch and anti-fogging capabilities. This product, which is able to pass many international safety standards, has a ventilation system that allows warm and cool air to pass through smoothly, which also prevents fogging from happening. The light-weight, flexible frame, as well as the adjustable temple angles, also means that users with various facial structures are all able to fit the product to their liking. The versatility of the Air Flow also allows users to alternate between three different eyewear products: the half-frame spectacle, full-frame spectacle and goggle. These features, as well as the personalisable colour pairings, allow wearers to showcase their individual characteristics.
