Variability of Eye Positions with EPS-21 Sun, Wind, and Dust Goggle
Abstract
Methods for providing advanced spectacle and goggle laser protection for visible lasers include reflective dielectric coatings and holograms, tuned for specific wavelengths. The primary advantage of these methods compared to the current fielded broad band absorptive dyes is the potential for increased visual transmission for a given amount of protection. However, dielectric coatings and holograms are angle and position sensitive such that the locations of the eye positions are critical for the desired protective effects. This study measured the right and left eye positions (lateral (x), vertical (y), and fore-aft (z)) of 20 military subjects fixating straight ahead while wearing an EPS-2l Sun, Wind, and Dust goggle using mechanical methods. The lateral and vertical eye positions were also determined using a reflective method for rapid data acquisition. The reflections from the goggle lens and eyes were captured with a digital camera and analyzed with a computer program. The results showed that the eye positions measured mechanically for this sample varied similarly about the x, y, and z axes.
