## React Optray Amber

The React Optray Amber is a **pair of sunglasses** for sport and everyday use that automatically adjusts its tint in just **0.1 seconds**. Its **ShadeTronic** technology is energy-autonomous using solar cells, so no battery or charging is required. The **filter categories S2 to S4** cover the range from medium to very dark – ideal when you switch between sun, shade and tunnels. The Amber design combines a silver mirror coating with a **tortoiseshell frame** and brings subtle street-chic to everyday cycling. With **UV400** protection and **polarized** lenses you're protected against glare and harmful rays. Total weight is **36 g**, and the glasses are made in Switzerland; a case and cleaning cloth are included, a **prescription clip** is optionally available.

## Technical details and features

At its core is a liquid-crystal-based **LCD** element that is powered via integrated solar cells and controls the tint continuously. According to the manufacturer, the **ShadeTronic** lenses darken up to 300 times faster and lighten up to 1200 times faster than classic **photochromic** lenses, keeping visibility practically stable without delay. The tint thus spans the range of **S2 to S4**, from brighter to very dark sunlight, similar to glacier or high-mountain light. The **UV400** filtering blocks UVA, UVB and UVC rays up to 400 nm, while the **polarization** reduces reflections and improves contrast. For eyeglass wearers, a suitable **prescription clip** is available, which can be fitted with prescription lenses by an optician. Additionally, the lenses are designed for **scratch resistance** and **shatterproof** performance, increasing everyday suitability on the bike. 

## Applications and benefits

The Optray Amber shows its strengths when lighting conditions change quickly – for example on **MTB** trails in the woods, on **Gravel** tracks with shifting shadows, or on **road** stages with tunnels and bridges. Because the tint reacts automatically and lightning-fast, fiddling with interchangeable lenses is unnecessary, which helps focus and safety. For the **Swiss** topography with passes, Alpine valleys and urban sections, the S2 to S4 range is particularly practical. When commuting or **driving**, the combination of polarization and UV400 ensures relaxed eyes even in harsh oncoming light. The robust design of the lenses also makes the glasses a reliable companion in training as well as on long tours. Media reports from the cycling scene underline the short reaction time and the practical benefits of the technology on the trails. 

## Contents, fit and care

Included are a **case** and a **cleaning cloth**, so the lenses stay clear for a long time and are protected on the go. For individual needs, the Optray can be adapted to prescription strength with an optional **prescription clip**; additional accessories like nose pieces are available. At only **36 g**, the glasses sit light and unobtrusive, making longer sessions comfortable. For care, we recommend rinsing the lenses with water and drying them with the included cloth to preserve the coatings in the long term. Thanks to **Swiss Made** manufacturing, you benefit from a neatly finished construction designed for durability in sporting use.
