Abstract : With the advent of lasers, the possibility of eye damage by electromagnetic radiation has become a problem wherever lasers are used because of the high brightness of lasers compared to ordinary extended sources. The eye is particularly vulnerable to radiation in the visible (400-700 nm) and near infrared (700-1200 nm) regions of the electromagnetic spectrum since radiation at these wavelengths can penetrate the outer portions of the eye to produce temporary or permanent damage to the retina as illustrated. Consequently, a requirement exists to provide ocular protection to troops at risk not only from ballistic fragments, but from laser energy exposure as well. In particular, devices are needed which are adaptable to spectacle, goggle and visor configurations. Past work has not resulted in the solution desired, but advances in materials over the past few years offer the possibility that devices having the desired characteristics may now be likely in the near future.
