Ballistic-Laser Protective Spectacles (B-LPS)

Laser eye protectors are designed for protection against a specific wavelength and have a certain amount of attenuation known as optical density (OD). Therefore, the laser's wavelength and the required OD must be known before selecting the proper eye protection. Because the U.S. Army frequently uses the ND:YAG laser at 1,064 NM and the ruby laser at 694.3 NM, eye protection with an OD of 6 or greater at these wavelengths will provide adequate protection from most lasers fielded by the Army. As laser technology advances, requirements for protective lenses will have to advance to match.

Early Laser Protective Spectacles were worn as a shield, over sunglasses or ballistic protection
Early Laser Protective Spectacles were worn as a shield, over sunglasses or ballistic protection.

The first Laser Protective Spectacles were slipped on over sunglasses or Combat Eye Protection for specific protection against laser hazards. The Ballistic-Laser Protective Spectacles (B-LPS) were designed to protect not only for laser hazards, but also ballistic and other hazards as well, so only a single system was needed.

B-LPS are designed for soldiers who wear prescription eyeglasses, the only laser eye protector with a prescription lens insert. The Prescription Lens Carrier (PLC) is available to hold the prescription lenses, fitting behind the BLPS’ protective lenses. The PLC and the prescription lenses are obtained through the soldier's post optometry clinic.

The same PLC can be used with the M40A1 gas mask by using an adapter, also available through the optometry clinic. For operational readiness, two separate PLCs were suggested, one for the B-LPS and one for the M40A1 mask.

Ballistic-Laser Protective Spectacles are available with four kinds of lenses: clear, grey (sunglass), and 2WL and 3WL laser protection. Each comes in its own frame, with a retaining strap and a hard plastic carrying case. The clear and grey lenses provide ballistic protection but not laser protection. If both ballistic and laser protection are needed, the 2WL or 3WL lenses must be used. One size fits all, from the 5th percentile female to the 95th percentile male.

MIL-PRF-44366B defines the requirements for Ballistic-Laser Protective Spectacles. B-LPS meets the American National Standards Institute requirements for occupational eye and face protection.
