Collection: Glasses for Running and Trail Running with Photochromic lenses


Every runner is in continuous and constant search of materials and new technologies that help them run better, faster, and improve performance. Furthermore, each runner has their own specific needs, as a long-distance runner has different requirements compared to a middle-distance runner or a trail runner. These differences extend from the cushioning of the shoe, to the type of socks depending on the specialty, the choice of trousers, technical shirts, hats, and glasses.

Let's delve into the specifics regarding running glasses for trail running.

Similar to shoes, glasses also vary, with some sports glasses being more suitable for running on concrete and light dirt roads, while others are designed specifically for the technical demands of trail running.

There are essential common characteristics that running glasses, regardless of the discipline, must possess for trail running:

    • Perfect vision of the track: It is essential to use a lens that allows the athlete to have a clear view of their path throughout the entire duration of their performance.
    • Lightness: The glasses must be ultra-lightweight. Even though we are talking about differences in grams, it is essential that the glasses are as light as possible.
    • Envelopment: The glasses must wrap around the face to provide optimal protection for the eyes, not only from lateral light but also from any debris that may be encountered along the way, such as dust, insects, leaves, and branches.
    • Comfort: The glasses must be comfortable and barely noticeable during sports practice.

Photochromic lenses for Running and Trail Running:

Photochromic glasses for running and trail running represent the pinnacle of technology currently available. Photochromic lenses are special lenses that react to UV-A, UV-B rays, and direct sunlight, triggering a reversible chemical reaction that causes the lens surface to darken. They return to their original color when the direct sunlight exposure ends. Glasses with photochromic lenses are equipped with dynamic lenses that adapt optimally to every change in light conditions encountered on the path.

    • Photochromic Running Glasses: 

      For running, marathons, half marathons, or simple training, using a photochromic lens is a definite advantage that every athlete, once they try it, will no longer want to give up. The benefit of using a photochromic lens for running is that it eliminates the need for the athlete to carefully choose the time of their activity. For instance, at dawn, the lens starts off transparent or slightly tinted and gradually darkens as the sunlight intensifies. Similarly, during late afternoon or sunset, it darkens and then returns to its original state as the light decreases. In cloudy weather, the lens adjusts its tint based on the changing light intensity.
      For those who practice marathons and ultramarathons, we recommend the DCHROM® photochromic lens. Compared to the photochromic smoke lens, it maintains a greater sense of comfort during prolonged use under intense light conditions.

Glasses from Trail Photochromic running: 

For trail running, using sunglasses with photochromic lenses is essential due to the frequent light-dark transitions along the route. Choosing between the DCHROM® and Smoke photochromic lenses is subjective for the athlete. The DCHROM® lens becomes darker than the Smoke photochromic lens during maximum exposure because it starts with a light tint resembling smoke, whereas the Smoke photochromic lens begins with a transparent tint.
We do not recommend choosing the DCHROM® lens for athletes who use glasses for outings and races that extend into the night, as it may become too dark even with strong artificial lighting. Instead, we recommend the Smoke photochromic lens in this case, as it can serve as a simple air protector.

    • Shatterproof lens: The photochromic lens for running and trail running is unbreakable. In the event of very strong impacts resulting from falls, collisions with leaves and branches, and similar situations, the lens distributes the impact across its entire surface, preventing breakage or the formation of fragments that could harm the eyes. Instead, it may develop a pattern resembling a spider's web, rendering the lens unusable but ensuring optimal protection for your eyes.
    • Frame material: All frames of photochromic glasses for running and trail running are made of TR90, a special composition of ultra-light and hypoallergenic nylon and carbon fiber. This material makes the glasses 20% lighter than those made with conventional materials, while also enhancing their resistance to impacts, durability over time, elasticity, and comfort.
    • Rubber parts: The rubber parts are made of soft, non-slip Megol, ensuring maximum stability of the glasses with photochromic lenses for running and trail, even in extreme conditions.
    • Adjustable nose pad: Many models in the collection have a nosepiece equipped with an aluminum core that allows adjustment to every nose physiognomy.
