React optray ice Sunglasses

The React optray ice is a sports sunglasses model for ambitious cyclists in Switzerland who don't want to rely on changing light. Thanks to ShadeTronic®, the tint of the lenses adapts automatically in only 0.1 seconds – from S2 to S4, without intervention and without delay. The integrated solar cells power the liquid crystals self-sufficiently, so no battery is required, making the glasses low-maintenance and ready for everyday use. The "ice" variant features a blue mirror coating that contrasts reddish details – ideal on forest trails or gravel sections. With UV400 protection and polarized lenses, vision remains clear and the eyes are reliably shielded. The optray is manufactured in Switzerland and weighs just 36 g, which makes it especially comfortable on long rides. This technology and craftsmanship were honored with the ISPO Award, further underlining the practical benefits.

• ShadeTronic®: automatic tinting in 0.1 s (range S2–S4) for consistent vision in sun, shade and tunnels.
• Solar self-sufficient: integrated solar cells, no battery, no charging.
• Ice lenses: blue mirror coating with contrast enhancement for reddish details.
• UV400 and polarized for protection against UVA/UVB/UVC and reduced glare.
• 36 g light, Swiss Made, designed for sporting use.
• Prescription clip available as an accessory for eyeglass wearers.
• Polarization is designed so that digital displays (bike computer, smartphone) remain easily readable.

Technical Details and Functions

The heart of the optray ice is an LCD lens construction that controls its tint continuously and thus smooths abrupt brightness changes. Compared to classic photochromic lenses, the technology reacts extremely quickly and keeps perceived brightness subjectively "constant", which builds confidence at speed on the road bike or on singletrack. The solar cells supply the necessary energy directly at the lens, eliminating cables and batteries and keeping the glasses particularly low-maintenance. The polarization is modified so that important bike computers and head-units remain easy to read, without disruptive blackouts. Additionally, the UV400 filter provides full protection up to 400 nm, while the tint range S2–S4 covers use from bright to very bright. The optray is manufactured in Switzerland, ensuring short supply chains, clean workmanship and precise quality control.

Use Cases and Benefits

Whether road bike, Gravel or mountain bike – the optray ice plays to its strengths wherever light changes are rapid and frequent. When moving from open fields into shaded forest, on alpine passes with tunnels or in the evening sun, vision stays stable, which eases line selection and noticeably reduces eye strain. Thanks to the contrast enhancement of the Ice lenses, reddish details like roots, rocks or leaves are better differentiated, increasing terrain readability. The combination of 36 g weight and Swiss fit feeling ensures the glasses are barely noticeable even on long rides. A prescription clip is available for eyeglass wearers so personal visual correction can be integrated without hassle. Thanks to the energy self-sufficient operation, the glasses are always ready – no charging required, whether for commuting through the Limmattal or a weekend ride in the Engadin.

Care, Accessories and Everyday Suitability

To keep optical performance consistently high, regular cleaning of the mirrored lens with a soft cloth and lukewarm water is recommended. If needed, the prescription clip can be retrofitted, making the optray ice versatile for everyday use or driving. The polarization helps reduce reflections without impairing the readability of digital displays – practical for bike computers and smartphones. Because the glasses operate without a battery, there are no charging cycles to maintain, and they are ready for use at any time. The robust, scratch-resistant and shatterproof design of the lenses increases durability in harsh outdoor use. Those who value Swiss Made get with the optray ice a locally manufactured product focused on precise workmanship and serviceability.

Award and Trust

The optray technology was awarded the ISPO Award 2022, which confirms the level of innovation of the ShadeTronic® solution. Special mention was made of the very fast adaptation, the practical benefits for high-speed sports and the consistent fit. For Swiss cycling this means: fewer glare moments, more control and more consistent vision – especially in demanding topographies with frequent changes of light and shadow. With its combination of UV400, polarization, S2–S4 coverage and solar autonomy, the optray ice consistently focuses on performance in everyday life and training. Anyone looking for sunglasses for "everything between a Zürichsee loop and an alpine pass" will find a technically refined, locally manufactured solution here.
