Single Lens Hiking Glasses with Mirrored Photochromic Lens DCHROM® Model SPEED VENT
SPEED VENT is DEMON's latest innovation in single-lens hiking glasses, featuring a mirrored photochromic lens DCHROM®. These glasses are designed for outdoor enthusiasts seeking both advanced photochromic lens technology and striking aesthetics. They are suitable for use in all lighting and atmospheric conditions throughout the year, thanks to the latest generation of photochromic lenses that darken in response to UV exposure.

The standout feature of this special lens is its initial light, veiled color, which allows hikers to use SPEED VENT for low-light outings or for returning after sunset, providing basic eye protection against airborne elements.
Versatile Applications:
Hiking and Trekking: SPEED VENT is ideal for hikers, from amateurs to guides. The wide frame provides maximum protection against leaves, branches, dirt, insects, and all potential eye hazards encountered in forest environments. Despite its size, these glasses weigh only 30 grams. The advanced DCHROM® mirrored lens starts with a slightly veiled color and reaches Category 3 in its maximum working phase, reflecting a purplish-red tone. It adjusts its tint to adapt to varying light conditions along the trail and is unbreakable, ensuring durability and maximum safety against strong impacts.
Ski Mountaineering: SPEED VENT is also well-suited for ski mountaineering. The broad shape offers optimal protection against air, dust, insects, and other hazards that may affect the eyes. The lens adapts by darkening or lightening with changes in ambient light, making it suitable for intense light conditions and prolonged use. The glasses provide optimal comfort with their ultra-light, elastic frame featuring hypoallergenic rubberized components and adjustable nose pads. Once tried, their performance will make them indispensable for your adventures.
Regardless of the discipline, SPEED VENT combines the benefits of photochromic technology with mirrored lens aesthetics, offering athletes glasses that excel in both style and function.
It is also important to note that the mirror coating does not alter external vision in any way, as the lens remains smoke-colored internally.
Technical Characteristics and Materials:
The new photochromic lenses DCHROM® undergo a reversible chemical reaction when exposed to UV radiation or sunlight, darkening in response. Once the light exposure diminishes, the lenses gradually return to their transparent state. Made from high-quality polycarbonate, this material significantly reduces lens weight compared to conventional materials and ensures safety by preventing fragment generation upon impact. These advanced filters also provide UV protection, ensuring comfort and reliability in eye protection.

The latest DCHROM® lenses represent an evolution in photochromic technology, starting with a slightly veiled color and reaching Category 3 during maximum activation. In addition to their rapid light-dark transition, they provide exceptional comfort even during extended exposure to intense sunlight.
The ultra-light TR90 frame, made from a special blend of carbon fiber and nylon, ensures that the overall weight of SPEED VENT hiking glasses is only 30 grams. Designed for athletes seeking technical excellence, maximum eye protection, and comfort, the frame's elasticity adapts to the head's contours for stability without compromising comfort.
SPEED VENT is a must-have for anyone seeking ultralight hiking and trekking glasses with photochromic mirrored lenses suitable for all outdoor activities. This material makes the glasses with DCHROM® photochromic mirrored lenses 20% lighter than conventional materials, more resistant to accidental impacts, and ensures longevity.
