Drawn from the one of the world's finest collections of cycling artifacts, Goggles & Dust collects over 100 stunning photographs from competitive cycling's heyday. Spanning the 1920s and '30s, Goggles & Dust: Images from Cycling's Glory Days celebrates the grit and determination of the bicycle racing pioneers who established the records, traditions, and distinct flavors of Europe's most hallowed races. The spirit of these hardy competitors was perhaps matched only by the resolve of the remarkable photographers who prevailed in all imaginable conditions, situations, altitudes and latitudes to capture unforgettable prints of the racers at work and play. From Alpine panoramas to hair-raising crashes and idyllic roadside celebrations, the gorgeous restored photographs in Goggles & Dust--most unseen since their original publication in the newspapers and magazines of the day--provide an indelible and delightful record of a more carefree and adventurous time.

In order to provide eye protection for military personnel, two types of laser-protective filter elements were developed for use as inserts in the Goggles, Sun, Wind, and Dust. The elements were designed to be snapped into the goggle frame in back of the standard ballistic lens. A total of 600 Type A filter elements with optical density greater than 4.0 at 400-532 nm and photopic transmission of 44% were delivered to the U.S. Army Natick RD & E Center. These elements met contract requirements with the exception of photopic transmission and resistance to sodium hypochlorite solution. A total of 275 Type B filter elements with optical densities exceeding 4.0 from 694-1064 nm were delivered to Marine Corps Systems Command. These elements measured substantially below the desired 25% minimum photopic transmission, exhibited excessive optical distortion and dye nonuniformity, lost abrasion protection after contact with sodium hypochlorite solution, and lost hardest adhesion after simulated exposure to sunlight.

Optical evaluations of lenses considered as candidates to replace the visor in the combat vehicle crewman's protective goggles are described. The four areas of optical evaluation were: spectral transmission, haze, optical distortion, and abrasion resistance. All of the lenses were found to have adequate properties of transmissivity and freedom from haze. However, none of the lenses submitted for evaluation were medically acceptable because of excessive optical distortion. The optical coatings under consideration to increase scratch resistance of the polycarbonate lenses provided only negligible improvement. If polycarbonate is determined to be the material of choice, a higher optical quality should be used and a better method of providing abrasion resistance should be sought.
