Abstract:

Prompted by a Product Improvement Program aimed at providing soldiers eye protection equal to that of the Ballistic Laser Protective Spectacles BLPS , Natick Research, Development and Engineering Center recently field tested four experimental laser ballistic lenses in the Sun, Wind, and Dust Goggle. All lenses used dye absorber technology. Field testing with Armor and Infantry military personnel resulted in data collected from more than 300 soldiers on over 80 variables. The tests included typical military operational tasks. The soldiers also wore the lenses during field training exercises and were surveyed about the lenses effects on mission performance. The Farnsworth-Munsell 100-Hue Test, a laboratory test which examines the effects of the lenses on color perception, was also conducted in both simulated daylight and reduced visibility conditions. Farnsworth-Munsell test results showed that performance was not seriously degraded by any lens in daylight illumination levels. In reduced visibility conditions there was impairment, and the degree of impairment was relatively consistent with what was expected from the respective lenses transmittance levels and specific lines of protection. There were also some negative mission performance issues raised that were more a function of goggle wear than lens performance.
