Double - windproof spectacles protect eyes from gale winds, from sudden changes in weather, and from dust or pollutants floating in the air, to prolong leisure such as mountain climbing, fishing or skiing. The spectacles have two tapered inclines from outside of each clear flat to bind to bows, and the length of the tapered inclines decreases toward other clear flat. And an elastic member beside the tapered inclines is fitted with the bows and a union link is located between two clear flats to bind them. |
