Vintage black metal aviator shooting glasses feature impact resistant UV MAX clear glass lens, cable hook temples and beige plastic sweat bar. Solid frame is lightweight but has that "beefier" feel to it. Lens width is 58 mm and vertical 49 mm both measured to the best of my ability. Front to back measures 130 mm and accommodates up to a 140 mm fit.   In storage for years, these are probably all the pairs that were picked out and sorted for minor defects by original manufacturer. I have cleaned them up and sorted any that may have excessive frame or lens defects. I recommend having an optical professional adjust any minor frame, temple, bridge and/or sweat/brow bar imperfections for added longevity.  
Using protective eye wear is a high priority safety precaution when operating firearms. Whether hunting or on the shooting range accidents happen. Hunters can get hit with errant birdshot, a ricochet or simply have excessive powder blow-back and wearing safety glasses will highly reduce the chances of eye damage. Shooting Glasses will also help protect eyes when spent cartridges are ejected and excessive muzzle flash occurs at the range.
Please read entire condition description before purchase. Please also be advised that 1980s decade is a best guess.
