Autobright Technology

Steiner's exclusive sunlight-adaptive Autobright technology automatically adjusts brightness to provide the best visibility in any lighting situation. Whether the sun is just below the horizon, shining directly overhead, or reflecting off water or snow at any angle, BluHorizons are designed to capture the right amount of light and reduce glare for optimal viewing.

Fast-Close-Focus

Minimal, stepless focusing of the central drive for fast, maximum sharp details from close range to infinity. Convenient and easy focusing.

Exceptional Durability

Thanks to the durable housing, water resistance and functionality in the temperature range from -20 °C to +70 °C. The non-slip NBR Longlife rubber armor is resistant to oils, acids and weathering.

BLUHORIZONS with Autobright technology - this is light protection for the eyes. Specially developed for all outdoor adventurers, BLUHORIZONS not only fit in almost any pocket, but are lightweight and at the same time extremely robust. This is the first and only binocular in the world to feature phototropic lenses.

Now, BLUHORIZONS with Autobright puts an end to this nuisance and offers long-lasting viewing pleasure on every sunny adventure. Without squinting and without being dazzled, you can observe the wide world in a consistently calm way.
