WARNING
(FOR LASER-PROTECTIVE VISORS)
Due to serious limitations imposed by the laser-protective visors on visual acuity outside the
aircraft as well as on flight displays within the cockpit, the laser-protective visors will only be
used when actual laser hazards exist. For day or night VFR flights at altitudes below low-level
flight, the pilot will analyze the current situation and decide whether flight should continue with
laser-protective devices in use. Considerations include local laser hazards, ambient light levels,
and terrain. Approval for use must be annotated on the flight crew’s mission brief.
The dark (bronze) laser-protective visors are not compatible with aircraft or ground support night
lighting and are not safe for twilight or night flights. DO NOT USE THE BRONZE LASER-
PROTECTIVE VISORS DURING TWILIGHT OR AT NIGHT.
The bronze laser-protective visors will change the appearance of and possibly eliminate some
red and/or green light sources. Testing indicates that some red lights take on an orange hue,
some cockpit warning lights are difficult to read though still visible, and some cockpit gages are
illegible. DO NOT USE THE BRONZE LASER-PROTECTIVE VISORS FOR IFR FLIGHT.
The light (green) laser-protective visors will change the appearance of and possibly eliminate
some red light sources. Testing indicates that some red lights take on an orange hue, some
cockpit warning lights are difficult to read though still visible, the distance some exterior red
lights are visible is reduces, and red cockpit map light are virtually unusable. USE EXTRA
CAUTION AT NIGHT.
Do not attempt to use more than one laser visor at a time. Use of multiple laser filtering visors
will not permit adequate vision to perform the required tasks.
If laser hazard occurs do not stare at the laser source. Some lasers have secondary
wavelengths that may cause eye damage; the laser-protective visors may not filter these
wavelengths.
The laser-protective visors are not intended to protect against broad-spectrum bright light. Do
not use the laser-protective visors to view solar eclipses, electric welding equipment, or other
potentially eye-damaging light sources.
Do not use the laser-protective visors as a substitute for other types of laser eye protection.
During maintenance or servicing of specific types of laser systems, wear correct eye protection
as specified in the appropriate technical manual.
The laser-protective visors reduce ambient light levels available to the eye. Allow eyes to
accommodate to reduced light before operations at dusk or dawn.
CAUTIONS
(FOR LASER-PROTECTIVE VISORS)
Scratching of laser lenses may degrade laser protection. Clean lenses according to
instructions. Replace scratched lenses with new ones.
Exposure of laser lenses to direct sunlight may degrade laser protection. Avoid unnecessary
exposure of lenses to sunlight.
