The SIOLS.System is unique: modular, customizable, and compatible with almost any prescription. You combine frames, shields, and optical clips according to your sport, season, temperature, or face shape – and upgrade whenever you need.
The frame architecture “hugs” your head. Long temples, wrap-around design, and balanced pressure distribution provide a secure fit – no slipping, wobbling, or pressure points.
Yes. Developed from optical research: up to +/- 15 dpt, progressive lens compatible, and a very wide field of view. With the front shield removed, you instantly have clear prescription glasses for breaks.
The SIOLS clip is inserted from the front. Benefits: fog-free, space for long lashes, and maximum flexibility with shield swaps (tints & functions).
Yes. The MAXIMUS adapter allows direct RX glazing, with lenses seamlessly integrated into the shield – almost invisible.
Only the optical lens (clip/adapter) is replaced. Frame and shield remain – sustainable and cost-effective.
Wrap-around design = secure, pressure-free fit.
Yes. Not only tints, but also functions: different ACM ventilation technologies for sports, temperatures, and conditions. With the DPX key system, swaps are quick, secure, and fingerprint-free.
Over 90% of movement is visually controlled. Impaired vision (fogged or too-dark lenses) reduces reaction time and performance. Clear sight is a safety and performance factor, not a luxury.
Your glasses should support, not distract: protection, perception, comfort. So you find your flow – in training, competition, or everyday life.
