LIEGI – Prescription sports sunglasses with mirrored photochromic DCHROM® lens
DEMON presents LIEGI, the new prescription sports eyewear designed for those who practice outdoor sports intensely and consistently and want the very best in protection, comfort, and visual quality.
Designed to deliver the same excellent performance and versatility as the top models in the collection, LIEGI stands out for its sporty, modern, and bold design, combined with a stable, customizable fit thanks to its adjustable nose pad and adjustable temples. The result is reliable, high-performance, and comfortable eyewear, even during the most dynamic activities.
Ideal for those looking for a single pair of glasses to use across different disciplines, LIEGI is perfect for road cycling, mountain biking, running, trail running, mountain sports, and hiking, offering visual protection, adaptability to changing light conditions, and the possibility of integrating optical correction through an internal clip.
Dynamic vision with mirrored photochromic DCHROM® lens
The technological core of LIEGI is its DCHROM® mirrored photochromic lens, category 1–3, designed to automatically adapt to changes in brightness.
This means the glasses respond naturally to different environmental conditions: when the light is softer, the lens remains more transparent, while as solar radiation increases, it gradually darkens up to category 3, providing greater visual comfort and more effective protection.
DCHROM® technology therefore allows you to use a single lens in many different situations, avoiding the need to constantly change glasses or lenses. It is a particularly useful solution for outdoor sports, where conditions often alternate between:
- full sun
- shaded areas
- woods and trails
- sudden light changes
- variable weather conditions
The mirrored finish also adds a high-impact sporty look, while helping improve glare management in bright light conditions.
Total protection for outdoor sports
LIEGI is equipped with UV400 protection, ensuring maximum shielding from both UV-A and UV-B rays. This means effective eye protection during every outing, whether in daily training sessions or long-duration activities.
The wraparound structure of the glasses helps protect the eyes from:
- wind
- dust
- insects
- small debris
- lateral light interference
This configuration makes LIEGI a truly technical sports eyewear model, designed not only to improve vision, but also to increase comfort and protection during movement.
Lightweight comfort and customizable fit
One of LIEGI’s strengths is the perfect balance between durability and lightness. The frame is made of TR90 Ultralight, a technical material highly appreciated in sports for its combination of:
- lightness
- flexibility
- durability
- long-lasting comfort
Weighing only 28 grams, LIEGI is extremely pleasant to wear even for many consecutive hours, reducing the feeling of pressure on the face during long rides, races, or intense training sessions.
Further enhancing the fit are:
- adjustable nose pad, for a precise fit
- adjustable temples, to further customize the fit and improve stability and comfort
These adjustments allow the glasses to better adapt to the shape of the face and the athlete’s needs, offering a more secure and stable feel during every activity.
Perfect for those who practice multiple sports
Thanks to its technical construction and DCHROM® photochromic lens, LIEGI is an extremely versatile eyewear model, suitable for numerous outdoor disciplines.
Road cycling
In road cycling, LIEGI effectively protects against wind, bright light, dust, and insects. The photochromic lens helps maintain more balanced vision on long rides, even when facing variable light, tunnels, tree-lined roads, or changing weather.
Mountain Bike
In MTB, protection is essential. The large wraparound shape of LIEGI helps shield the eyes from branches, leaves, kicked-up dirt, and small debris. The DCHROM® lens adapts to the continuous changes in brightness typical of trails, improving visual perception through woods, clearings, and technical descents.
Running
During running, LIEGI offers clear, protected vision, reducing discomfort caused by wind and dust. The lightweight frame and stable fit also make it ideal for longer training sessions.
Trail Running
In trail running, the ability to adapt to light is a real advantage. Constant transitions between shade and sun require a versatile lens that is ready to react: DCHROM® performs this task automatically, improving comfort and concentration.
Mountain sports and hiking
In the mountains, light changes quickly and UV intensity can increase significantly. LIEGI offers protection, lightness, and comfort, making it an ideal ally during trekking, high-altitude walks, and long excursions.
Prescription sports glasses with internal optical clip
LIEGI is also designed for those who need vision correction during sports activity. It comes with a prescription clip, a practical and functional solution that allows the glasses to be transformed into true prescription sports eyewear.
The optical clip supports:
- maximum sphere: -5.00 / +4.00
- cylinder (astigmatism): +/- 1.00

- progressive lenses
This compatibility makes it suitable for a wide range of visual needs, allowing you to practice sports with greater safety, precision, and comfort.
