Revision Presents: Invisible Danger – Laser Devices, Effects and Laser Eye Pro

Wednesday, September 16th, 2020

Since July, reported incidents of laser attacks on law enforcement have skyrocketed around the nation leading to a variety of eye effects and injuries, including reports of partial blindness. While handheld lasers aren’t new, their widespread use with intent to harm is increasing, just as the demand for laser protective eyewear to prevent effects and injuries. We’ve learned there are a lot of questions from end-users about lasers, and Revision has offered the following article with some education about the laser threat and how to combat it. Revision has been at the forefront of laser and ballistic protective eyewear solutions for the past decade.

INVISIBLE DANGER – LASER DEVICES, EFFECTS AND LASER EYE PRO

One of the latest tools of mayhem employed by street protestors is the handheld laser. Easily concealed, simple to use, and cheap to the point of disposability, they pose a serious threat to tactical law enforcement officers working a crowd control detail.

LASER SPECS

There are three important laser device specs to note when looking for laser eye protection. The power level of the device (measured in milliwatts), the color of the laser it emits (expressed as its wavelength in nanometers), and beam divergence (measured in minute of angle or milliradians.) We’ll cover power and color in more detail, but beam divergence is a complex sounding term that indicates how tightly focused the laser beam is. Wider beams are less of a threat.

MORE POWER

Handheld lasers used in street protests range from mostly harmless low-power keychain laser pointers to high intensity handheld lasers that rival the power of lasers used by the military to mark targets miles away.

How do you know the level of danger you’re facing when the crowd is shining lasers at you? Bottom line, you won’t. Like you, the protesters slinging light beams at you probably don’t even know how powerful their handheld lasers are.

Sure, the U.S. FDA regulates all laser products for safety. But, handheld lasers are considered a novelty, often sold on the gray market, imported by the shipload, and are among millions of products the government is supposed to inspect. It’s not surprising that laser safety regulation is a massive game of whack-a-mole that’s got regulators on their heels.

And because it costs more to make a less powerful laser that complies with safety standards than a more powerful one that doesn’t, it’s common to order a 3 mW laser from the internet and get one that puts out 10 or more times the stated output. So, it’s safe to assume every laser you see on the street is powerful enough to be dangerous, regardless of what the label says.

POTENTIAL INJURY

Laser danger comes in a few forms, the most feared is irreversible injury caused by a highly focused light burning the retina. The more common, but just as serious threat posed by lasers is the loss of situational awareness.

A laser in the eye has the same effect as any bright light source, it’ll first elicit a startle response causing you to blink. If you continue looking into the laser, you’ll be dealing with glare that obscures your vision and if you look into it long enough you’ll get temporary bright spots, called afterimages. While these effects aren’t as severe as permanent blindness, situational awareness is the last thing you want to lose when flying bricks and homemade pyrotechnics are in play.

INVISIBLE DANGER

Good news: you’ve got an involuntary blink response. Bad news: The blink response only occurs if the offending light is in the visible spectrum, and cheap lasers are often contaminated with invisible, IR and near-IR light.

This means a dim, 5mW visible laser could be pumping out hundreds of mW of light in the near-IR spectrum, and you won’t know it until you feel your eyes itching and burning for no apparent reason. By that point, that light is cooking your retina.

HOW DO YOU STOP A LASER

At the simplest level, a laser’s color is its Achilles heel. Want to stop a red laser? Put a red-absorbing filter in its path. Generally laser protective lenses will look the opposite of the color they absorb.  Of course there’s more to blocking a laser than that, but a key consideration when looking for laser eye pro is knowing the color of the light you want to block. Eye pro manufacturers list this spec as a specific wavelength or a range of wavelengths in nanometers (nm).

LENS CONSTRUCTION MATTERS

To make a lens that stops a laser means choosing a dye that absorbs light at the same wavelength as the laser and incorporating it into the lens. This can be in the form of a coating applied after a glass or polymer lens is made, or by mixing the dye into the base material of a polymer lens before it’s molded into shape. The later method of construction results in a much more durable form of laser protection, since the dye is impregnated into the lens and can’t be scratched off.

Most laser protective lenses are made for use in a laboratory or on a manufacturing line where getting punched in the face or fragged by a BB-covered M-80 isn’t a concern. Keep that in mind when looking for laser eye pro that’ll be used on the street. There are only a few companies making laser eye pro that also provides mil-spec ballistic protection.

CHOOSING THE RIGHT LENS

It’d be great if there was one lens that could block all laser wavelengths, but there isn’t. Knowing that blocking a laser is accomplished by filtering its particular wavelength of light, the practical cost of protection for a given color of laser is limiting the ability to see that color. So, a lens that would block all laser colors would need to filter out all colors of light, and that lens would essentially be impossible to see through.

Because each lens can only provide laser protection in a certain wavelength, or range of wavelengths, determining what color lasers you’re likely to face on the street is critical in choosing a protective lens.

LASER EYE PRO SPECS

Carefully consider the time of day you’ll use the laser eye pro. Nighttime is the right time for mayhem, so you’re going to want to get lenses that aren’t so dark that they can’t be used at night. The spec that tells you how much light a lens allows through is called its visible light transmission (VLT.) VLT tells you how much regular light a lens allows to pass though it as a percentage. Higher percentages allow more light to pass.

Another important spec you’ll see is a lens’s optical density (OD). OD tells you how much of a laser’s light is blocked by the lens. It’s given as a number from 0 generally up to around 7, with higher numbers offering the most protection. Each additional OD absorbs ten times as much laser light, so a lens with OD 3 absorbs 10 times as much light as a lens with OD 2.

Practically speaking, the higher the OD, the more laser energy a lens can absorb. The higher the VLT, the more natural light is passing through the lens. 

BEWARE OF IR ONLY LENSES

Before heading out to work a protest with the eye pro that came with your IR aiming lasers, confirm those lenses also provide protection in the visible light spectrum. IR rated lenses are generally only good for stopping lasers in the IR/Near-IR spectrum and won’t necessarily offer protection against visible lasers.

LOOKING FORWARD

The current limitations of protective laser lens technology means the need for situational awareness and broad spectrum protection are at odds with each other. Want to see everything? You have to give up protection. Want to be protected from the widest range of threats? You’re going to have to decide how much visual awareness to give up. 

The threat of lasers to guys on the ground is still emerging, as is the response from companies making eye protection. Cutting edge research and development in tactical laser eye protection is focused on finding a no-compromise solution that provides full spectrum laser protection, uninhibited vision, and mil-spec ballistic protection using high tech solutions that can survive the rigors of the street and the battlefield.

Bollé Launches First Ever Augmented Reality Sunglass Experience For Smartphones

Tuesday, June 23rd, 2020

New AR Technology Allows Users to Experience Bollé Phantom lenses on their Smartphone and Purchase From a Participating Retailer.

Lyon, France, (JUNE 23, 2020) – Bollé, maker of the most innovative lenses in the world is forever changing the way people try and buy sunglasses. With the introduction of an exclusive Augmented Reality Sunglass experience, shoppers can now try-out Bollé’s flagship Phantom lens technology without ever having to physically touch the glasses. 

Partnering with QReal and M7 Innovations, Bollé’s AR experience is a first for the sunglass industry. Within Instagram, the demonstration invites users to try out Bollé’s Phantom lens through one of the brand’s iconic models – the Chronoshield. After seeing the glasses on their face, users simply flip their camera from selfie-view to front-facing and Phantom lenses are superimposed on their actual view. Users then introduce sunglass effects like high contrast, anti-fog, and light-adaptive into their real surroundings to see Phantom lenses in action. Once users select a lens that suits their style and needs, they can search for a retailer that carries Bollé. 

“AR is routinely used for try-on and certainly enhances the buying experience. But AR for try-out, this is a first,” said Louis Cisti, Vice President of Global Marketing for Bollé Brands. “In the new normal of retail, Bollé recognizes that safety is now the most important thing. Consumers demand shopping encounters that minimize physical interaction. However, when it comes to buying premium sunglasses, they still have high expectations and expect to see tangible benefits. Bollé’s AR try-out does all that heavy lifting. Shoppers get to see perceivable performance benefits before making a purchase.” Cisti continued.

Using AR, users will experience several unique Bollé lens features that demonstrate Phantom’s superiority for spring skiing, cycling, running and more: 

• Light Adaptive Technology: the user is presented with a slider that allows them to change their exposure, making the scene brighter or darker. They watch Phantom’s molecular photochromic filter adapt to changes in ambient light. 

• Platinum Anti-Fog Treatment: The user’s view begins to fog up, simulating the fogging that occurs from sweat while riding, hiking, or spring skiing. Fog condenses outside the glasses, but the view through the sunglasses remains crystal clear, mimicking the real-world performance Phantom Lenses in a perspiring situation.

• High Contrast: The scene outside the glasses remains natural, but the user is able to experience improved color and depth perception as they look through the Phantom lenses. 

For the Try On part of the experience users will be able to see how they look in the Bollé Chronoshield, a new take on an original style from the 1980s. The Chronoshield offers an extra wide field of view, ideal for visual comfort and protection against wind or debris. Venting ensures the lenses never fog up and the adjustable Thermogrip nose-pads and temple tips gives a custom fit while making sure they stay in place.

To try-out Phantom Lenses using this augmented reality experience, users can either click on a QR code that will be included in Bollé marketing materials or may visit this link using their: Merged Single Lens Experience
