Laser Glare Protection eyewear for pilots

One technology that is often suggested to help reduce laser/aircraft illumination hazards is Laser Glare Protection (LGP) eyewear, or “anti-laser glasses.” These have been developed specifically to protect pilots against too-bright laser pointer illuminations.

Below is general information about selecting and using LGPs, as well as a list of LGP eyewear manufacturers we’re aware of.

General information about Laser Glare Protection

List of Laser Glare Protection eyewear

LaserPointerSafety.com is aware of the following LGP eyewear which is specifically intended for pilots.

GlareShields from NoIR

NoIR developed GlareShields with input from Los Angeles Police Department helicopter pilots. LAPD used these both to provide protection, and to help track down ongoing laser misusers. (See the story here; the link to KABC’s report also mentions use of the laser glasses.)

As of July 2011, there are three models. PBG reduces green by 99.5%, blue by 97%, has 49% transmittance for low-light conditions, and has “good” instrument panel visibility. AG2 reduces green by 99%, has 53% transmittance for low-light conditions, and has “excellent” instrument panel visibility. BGR is for full sun conditions; it reduces green, blue and red by 90-97%, with 29% transmittance for full sun conditions.

Laser Armor Aviator Glasses from Night Flight

According to Night Flight, Laser Armor Aviator Glasses “were designed to support the specific operational requirements of pilots and crewmembers in civil aviation (fixed and rotary-wing), including airborne law enforcement, Search&Rescue (SAR), Emergency Medical Services (EMS), commercial airline and cargo transport.” They absorb green and blue beams without degradation of visual acuity or cockpit display panel color recognition. A brochure with more information is available.

metaAIR eyewear from Metamaterial Technologies Inc.

MTI uses a unique holographic-based technology to form layers that reflect 532 nm green laser light, and enhance color balance and discrimination. According to the company, the result is metaAIR eyewear, with "the world's best transparency, laser protection and color balance."

The eyewear is said to have an Optical Density between 2 and 5, meaning that it will attenuate the amount of 532nm light reaching eyes by 100 to 100,000 times. The frame is wider at top, sides and bottom, to block light coming from directions other than the front.

MTI originally developed the holographic laser-reflecting technology for use in windscreens. The goal was to protect pilots without the need for eyewear. However, windscreen modifications require a slow, multi-year process of obtaining governmental and airline approval. In addition, the cost to modify windscreens is much higher than the cost of one or two pairs of eyewear. So eyewear was a natural choice for the first commercially available laser protection product from MTI. According to its metaAIR website, the company may also produce glare shields using the same technology.

As of late February 2019, MTI is taking pre-orders for its eyewear, distributed by Satair, which will be available "spring 2019."

LaseReflect Aviator from Iridian Spectral Technologies

LaseReflect Aviator glasses normally reflect 532 nm green and 1064 nm infrared, but also can be special-ordered to reflect violet, blue and red light. Between these laser wavelengths, visible light transmission is over 80%, as shown by the transmittance diagram below. A press release announcing the glasses is here.

Flash Fighters from Kentek

These are dye-based Laser Glare Protection eyewear in metal aviator frames. They have “near perfect” color recognition for day or night use, with no back reflection. Visible light transmission is 57%. The chart shows the protection against blue (440 nm), green (532 nm) and red (640 nm). A product data sheet is here.

Laser-Gard from Sperian

The Sperian Laser-Gard model we examined is for nighttime protection against the most common green laser pointers. It has a very narrow-band filter (25 nanometers) that is claimed to eliminate 99% of 532 nanometer laser light. Because of the narrow bandpass, they do not adversely degrade color recognition.

These glasses have been tested by pilots for a major U.S. airline, who confirm that they can still safely distinguish colors in the cockpit (including green on indicators and LCD displays), and on airport lighting. Informal testing by LaserPointerSafety.com shows that Laser-Gard turns green laser pointer “hits” from being uncomfortably bright, to being minor and manageable. Because 1% of laser light is transmitted, it is still possible to tell where the laser is coming from. This aids in identifying perpetrators.

Sperian has four models of Laser-Gard; two for daylight use (bronze-colored sunglasses that also have laser protection), and two for nighttime use (salmon-colored glasses with maximum light transmission except for the laser wavelength). Within each group, there is green-only protection, and green-and-red protection. The cost for the nighttime, green-only Laser-Gard glasses we examined is $99. One U.S. source is Rockwell Laser Industries.

Laser Defense Eyewear from PerriQuest

There are two models of PerriQuest Laser Defense Eyewear: PerriQuest Night “is designed to combine three-wavelength laser blocking coverage [red, green and blue] with high ambient light and more red spectrum to preserve maximum visual acuity and night vision.” Green-tinted PerriQuest Day also has three-wavelength laser blocking and adds “sun protection and UV-blocking for daytime use.”

The lenses are glass and have been processed by Carl Zeiss Vision Laboratory. As of July 2015, the glasses are available for pre-order; a shipping date is not indicated. According to a media story, a pair of glasses cost $400.

According to the manufacturer, the glasses maintain color discrimination so cockpit and airport lights are still visible and remain color-distinguishable. Graphics on their website show how colors (mostly reds) may shift slightly in hue but are still distinguishable.

This chart from PerriQuest shows how colors shift when seen through the lens. For example, the bright green at a*=-70, b*=+80 shifts to a more yellow green; reds shift to orange. But because the shifted colors remain visible and stay within the same general hue, the manufacturer says this “eliminates the possibility of color confusion.”

LazrBloc from Revision Military

Revision Military’s LazrBloc Laser Eye Protection (LEP) combines leading-edge laser dye technologies with Revision’s robust protective eyewear products. Formulated using computer modeling and proprietary laser absorbers, LazrBloc lenses maximize laser attenuation—optical density—and minimize effect on the field of vision—maintaining the highest possible visible light transmission (VLT). Revision’s LazrBloc laser lenses deliver ballistic protection in accordance with American and international industrial standards, as well as U.S. military standards.

Laser Dazzle Visor from Folium Optics (liquid crystal shutter under development)

U.K firm Folium Optics as of summer 2017 is developing an anti-laser shield consisting of two thin layers of plastic containing liquid crystals. When laser light is detected, the shield acts as a shutter to block the detected wavelength, while still giving good visibility to other colors.

It can be integrated into visors, goggles or other eyewear. Below is an “early prototype” showing detectors above the nose bridge and batteries on one earpiece:
