LIEGI – Sport Prescription Glasses with Mirrored Multilayer Shield Lens and Adjustable Temples for Running, Cycling, Trekking, and All Sports
LIEGI is the new sport prescription model from the Demon line, designed for those who practice outdoor sports and want the very best in protection, comfort, stability, and vision correction. It is the ideal solution for anyone who wants to tackle training sessions, rides, and competitions with sharper vision, a secure fit, and a bold sporty look.
Whether you are riding on the road, running on asphalt, tackling a mountain trail, or enjoying multisport activities, LIEGI is made to support you in every situation with a lightweight structure, wide coverage, and an even more customizable fit thanks to its adjustable temples. This is an important technical detail that allows the glasses to adapt better to the shape of your face and to the dynamic demands of sports activity.
The single-lens shield design delivers an aggressive, modern look, but above all it offers a real advantage: a wide field of view, wraparound protection, and fewer visual interruptions. This allows you to stay focused on your line, pace, terrain, and performance, while benefiting from an effective barrier against wind, dust, insects, and debris.
DMIRROR Multilayer Shield Lens: protection, contrast, and visual comfort
The technological core of LIEGI is its DMIRROR multilayer shield lens, developed to provide more comfortable and responsive vision during sports activity.
The multilayer treatment helps improve contrast perception and environmental readability, making it easier to distinguish:
- changes in surface between asphalt, gravel, dirt, or trail
- shadows, contours, and elevation changes
- differences between direct light and shaded areas
- side obstacles, small debris, and terrain variations
The DMIRROR lens is especially appreciated by those who practice outdoor sports in bright light conditions, because it helps manage brightness and glare while maintaining clean, sharp vision. It also offers a very useful advantage for athletes who use sports devices: it ensures ideal light management without compromising the readability of LED displays on bike computers, smartwatches, and digital instruments.
The result is more stable, more precise, and faster-to-interpret vision, which is essential when immediate decisions must be made during activity.
Integrated vision correction: sport and eyesight in one solution
LIEGI is designed for those who need vision correction but do not want to give up the benefits of true sport eyewear. It is not simply a pair of glasses with a clip-in insert, but a solution designed to integrate prescription correction in a functional and stable way, while maintaining a wide field of view and a fit suitable for movement.
The internal insert allows prescription lenses to be mounted in a practical and secure way, so you can carry out your sport with greater visual precision and less strain. The positioning of the prescription follows your sporting posture more effectively and reduces distractions during performance.

Adjustable temples: personalized comfort and superior stability
One of the distinctive features of the new LIEGI model is the presence of adjustable temples, a characteristic that adds even more versatility and precision to the fit.
The adjustable temples allow the glasses to adapt better to the shape of the face and to the position assumed during sports activity. This means:
- greater stability during movement
- better pressure distribution
- long-lasting comfort even in longer sessions
- less need to readjust the glasses during training
For those who practice sports intensely or for long periods, this detail truly makes the difference: LIEGI stays more secure, more comfortable, and more precise to wear.

In trail running, the DMIRROR lens helps you read the trail better, perceive terrain changes, and identify obstacles, roots, or elevation changes more quickly. The wraparound coverage also protects against branches, leaves, wind, dust, and insects.
For road running, LIEGI is an ideal choice for defending against intense light, debris, and wind, while maintaining sharp vision and a stable fit even with sweat and constant movement.
It is also suitable for:
- fitness walking
