Dimming the problem: Gentex targets headlight glare with new smart sun visors. For many drivers, nighttime driving has become increasingly uncomfortable. The complaint is heard everywhere - from customer surveys to service departments and even federal regulators. Headlights on modern vehicles are brighter, whiter, and more intense than ever before. While those lights are designed to improve visibility for the driver using them, they are creating a growing problem for everyone else on the road: glare. Now one supplier believes it has a practical solution. Gentex Corporation, the Michigan-based technology supplier best known for pioneering auto-dimming rearview mirrors, plans to introduce a new type of transparent, dimmable sun visor starting in 2027. The company says the technology is designed specifically to reduce the blinding glare drivers experience from oncoming headlights. For dealers and the automotive industry, the innovation highlights both a growing customer complaint and a potential new feature that could improve safety and driver comfort. A global problem drivers can't ignore. Headlight glare is no longer just a minor annoyance. It has become a widespread issue as vehicles adopt increasingly powerful LED and laser lighting systems. A 2024 European survey on road glare conducted by the Fédération Internationale de l'Automobile revealed just how widespread the problem has become. According to the study, 71 percent of drivers say headlight glare is intolerable or extremely annoying. Nearly one-third of drivers report they almost always feel dazzled by oncoming headlights. Even more concerning, 51 percent say they sometimes squint or briefly close their eyes to cope with glare, while 58 percent report difficulty seeing objects on the road during these moments. About 30 percent of drivers say the glare leaves a lingering image in their vision or even causes physical discomfort. Those findings are prompting regulatory attention as well. The United Nations Economic Commission for Europe recently launched a dedicated task force focused on glare prevention and evaluating whether vehicle lighting regulations need updating. In the United States, driver complaints have also reached regulators. The National Highway Traffic Safety Administration reports that headlight glare is now the number one lighting-related complaint submitted by drivers. Technology designed to adapt in real time. Gentex believes its new dimmable visor technology can reduce that glare without blocking a driver's view of the road. Unlike traditional opaque sun visors that simply flip down to block sunlight, the new design incorporates a transparent panel that can darken electronically. Drivers can still see through the visor, but the panel automatically dims to reduce incoming light. The technology relies on the same electrochromic science that powers Gentex's widely used auto-dimming mirrors. Light sensors detect the intensity of incoming glare, while proprietary electrochromic gels and specialized glass coatings adjust the tint level. A microprocessor running advanced algorithms controls the process, changing the tint in real time to maintain optimal visibility. The goal is to reduce harsh light from oncoming vehicles while allowing the driver to maintain a clear view of the road. Building on a proven safety feature. Gentex already has decades of experience in glare mitigation through its auto-dimming mirror technology. These mirrors automatically darken when bright headlights shine from vehicles behind, reducing glare in the rearview mirror. In 2025 alone, the company shipped roughly 45 million auto-dimming mirrors globally. Yet despite their benefits, the technology is still installed on only about 40 percent of vehicles worldwide. Auto-dimming mirrors work using electro-optical components that darken the mirror surface to exactly the level required. The system relies on light sensors to detect glare, electrochromic materials to adjust tint, and microprocessor-based controls that fine-tune the response. The benefits are well established. Eliminating rearview glare improves reaction time, reduces driver fatigue, and helps maintain driver focus during nighttime driving. The new visor technology essentially brings that same concept to the front of the vehicle, where glare from oncoming traffic is often the most disruptive. Expanding electrochromic technology throughout the cabin. Gentex is also expanding the use of electrochromic glass across other parts of the vehicle. Sunroofs and sidelites - side windows located near the roofline - are already incorporating similar dimmable technologies. These systems can switch between manual and automatic modes and offer a wide range of light control. Some electrochromic glass solutions can adjust visible light transmission from more than 55 percent down to less than 1 percent. Drivers can even experience gradual "grayscale" transitions rather than a simple on-or-off tint. The glass also delivers additional benefits beyond glare reduction. When darkened, it can block up to 88 percent of total solar energy entering the cabin. That reduces heat buildup while maintaining a neutral gray color and extremely low haze, helping preserve clear outward visibility. For automakers, these technologies are becoming part of a broader strategy to improve comfort and safety without relying solely on mechanical solutions. A feature that could soon reach showrooms. Gentex expects the dimmable sun visors to debut first in luxury vehicles beginning in 2027, where advanced technology features often launch before expanding to mainstream models. For dealers, the introduction could eventually create a new feature category to explain to customers - one that directly addresses a complaint many drivers already have. Headlights will likely continue getting brighter as automakers pursue better nighttime visibility and advanced lighting technologies. That means the challenge of glare is unlikely to disappear. But if Gentex's new dimmable visors perform as expected, they could provide drivers with a simple solution: reducing glare without sacrificing the ability to see clearly down the road. And in today's increasingly complex vehicle environment, sometimes the most valuable innovations are the ones that simply help drivers keep their eyes comfortably on the road.

Gentex Corporation has launched the Ops-Core Voice Projection Unit, an accessory for its Special Operations Tactical Respirator half mask designed to enhance communication for tactical operators. The VPU projects the wearer's voice clearly with three adjustable volume levels, enabling effective team coordination whilst wearing respiratory protection. The device attaches tool-free to the SOTR mask and connects to the existing microphone port, allowing operators to switch between local voice projection and secure wired communication with standard Push-to-Talk devices and tactical headsets. This enables users to maintain respiratory protection whilst preserving mission capability. The VPU is available now for purchase through authorised Gentex Corporation distributors. Gentex provides personal protection and situational awareness solutions for defence forces, emergency responders and industrial personnel.
