Irid is a technology developed by an Italian optics research firm focused on improving how photochromic lenses respond to light. The system is designed to automatically adjust tint levels based on brightness conditions, without using any batteries.
The technology is currently applied to helmet visors and can also be used in goggles, sunglasses, personal protective equipment, automotive applications, and equipment for armed forces. The visor can adapt its tint to light in approximately 0.09 seconds, allowing for a near-instant adjustment between lighting conditions.
Moving Beyond Traditional Photochromic Lenses
Conventional chemical-based photochromic visors react to ultraviolet rays. These systems often take close to a minute to transition from clear to dark and can activate even in cloudy conditions.
Irid approaches the process differently. Instead of relying on chemical reactions triggered by UV exposure, it uses liquid crystal technology combined with a solar-powered system. The result is a visor that adjusts its tint in less than one second.
How the Irid System Works
The helmet visor built with Iridโs light-sensitive photochromic system includes several components. It uses a liquid crystal film, a solar panel mounted at the top of the visor, a high-precision base lens, and an advanced mirror coating.
When light hits the small solar panel, it generates power instantly. This energy activates the liquid crystal film embedded in the visor, allowing it to change tint automatically. Because light powers the system directly, it does not require a battery.
Instant Tint Adjustment
Iridโs visor technology can adjust between the S1 and S3 filter range. It starts from a clear state with approximately 70 percent visible light transmission (VLT). As brightness increases, the tint deepens automatically.
Moreover, the transition happens in less than one second, allowing riders to move between different lighting conditions without manually changing visors or waiting for a slow chemical reaction.
Designed for Multiple Applications
Although Irid currently highlights the technology in motorcycle helmet visors, the company designed the system for broader use. Manufacturers can integrate it into goggles, sunglasses, personal protective equipment, automotive glazing systems, and military applications.
Built for Real-World Riding
Irid visors come in three tint shades: blue, clear, and smoke. In addition to automatic tint adjustment, the visor includes a special anti-fog treatment to improve visibility in varying weather conditions. It is also completely waterproof, making it suitable for everyday motorcycle use.
However, the Irid visor starts at approximately 320โฌ, around $496. A helmet equipped with the Irid visor system starts at 999โฌ, around $1181.
