Glasses for Running and Trail with Photochromic Mirrored Lens DCHROM® Model SPEED VENT
SPEED VENT glasses are designed for road running and trail running, featuring the new DEMON photochromic mirrored lens. These glasses are ideal for runners seeking a photochromic lens combined with a strong aesthetic impact, suitable for use in all light and weather conditions throughout the year, thanks to the latest generation of photochromic lenses that darken as they reflect light.
The unique feature of this lens is its initial very light tint, allowing athletes to use SPEED VENT in low light conditions or when returning after sunset, providing essential protection for the eyes from the elements.
As shown in the accompanying image, the lens is versatile, performing well in all light conditions, especially in critical low light situations (e.g., very cloudy or rainy weather and post-sunset runs) as well as in bright conditions.

Types of Sports:
Trail Running: SPEED VENT is ideal for trail running and suitable for both amateurs and professionals. The wide frame offers maximum protection from leaves, branches, dirt, insects, and other potential hazards in forested areas. Despite its large size, the glasses weigh only 30 grams. The DCHROM® latest-generation mirrored lens features a slightly veiled starting color and, at maximum darkening, reaches category 3, reflecting shades of red, purple, and blue (depending on the chosen version). The lens adapts to changing light conditions and is unbreakable, ensuring safety even during strong impacts. The glasses also feature an adjustable nose pad and non-slip rubberized components for stability during jumps and vibrations.
Road Running: SPEED VENT is excellent for road running, whether for short or long distances. The wide shape provides optimal protection for the athlete's eyes from air, dust, insects, and other dangers. The lens adapts by darkening and lightening with every change in street lighting. This lens is also recommended for very bright conditions (typical of summer) and prolonged use. The frame is ultra-light and elastic, featuring hypoallergenic rubberized parts and an adjustable nose pad to ensure optimal comfort.
Cross Country, Track Running, and Other Disciplines: SPEED VENT is recommended for all running disciplines. They offer maximum protection for the eyes from light and accidental impacts, ensuring stability and comfort. These glasses are ideal for those seeking lightweight, protective eyewear with an aggressive aesthetic.
Regardless of the discipline, SPEED VENT combines the photochromic lens with the aesthetics of a mirrored lens, providing runners with glasses that have strong visual appeal along with advanced lens technology.
Note: The mirror color does not alter external vision, as the internal lens is smoke-colored.

Technical Characteristics and Materials:
The new DCHROM® photochromic lenses darken when exposed to UV radiation or sunlight and gradually return to their transparent state when the light source is removed. Made of high-quality polycarbonate, these lenses are significantly lighter than conventional materials and ensure safety by not producing harmful fragments upon impact. These lenses also provide UV protection, ensuring both comfort and safety.
The DCHROM® lenses start with a light tint and reach category 3 at maximum exposure. They offer a quick light-dark transition and provide a notable sense of eye relaxation, even on bright and prolonged sunny days.
The ultra-light frame is made of TR90, a special composition of carbon fiber and nylon, ensuring that the glasses weigh only 30 grams. Designed for athletes, these glasses are constructed with technical materials that guarantee maximum protection and safety. The elastic frame adapts to the head for optimal comfort and stability.
The adjustable nose pads and rubberized components are made of soft, hypoallergenic Megol, ensuring maximum stability and preventing slippage caused by vibrations and head movements.
SPEED VENT is essential for those seeking ultralight photochromic mirrored running glasses for road running and trail running on dirt roads and in the mountains. This material makes the DCHROM® running glasses 20% lighter than conventional materials, more resistant to impacts and stress, and more durable over time.
