Combination Antifog/Antiscratch Coating Applied to Special Protective Eyewear, Cylindrical System (SPECS): Experimental Trials

摘要

Though the eye is extremely susceptible to damage, even by small, low-velocity projectiles, the eye can easily be protected with proper eyewear. Current military protective eyewear systems, however, are prone to fogging. Antifog coatings exist, though have traditionally been incompatible with antiscratch coatings required to protect the polycarbonate base from which most military eyewear is made. The report documents one effort in which an antifog/antiscratch coating is applied to a military item. The experimental antifog/antiscratch samples evaluated in this particular study do not demonstrate durable antifog capabilities. Scratch resistance and resistance to insect repellent (DEET) were inferior as compared to standard samples. Since only one combination antifog/antiscratch coating was investigated for this particular study, additional combination antifog/antiscratch coatings warrant further investigation as they become available.
