Autobright Technology

Steiner's exclusive Autobright sunlight-adaptive lens technology automatically adjusts brightness to ensure the best view in any lighting situation. Whether the sun is just below the horizon, shining directly above us, or bouncing off water or snow from all angles, BluHorizons are designed to capture the right amount of light and reduce glare for optimal vision.

Fast-Close-Focus

Minimal, stepless focusing on the center drive for fast, pin sharp details from close to infinity. Comfortable and easy focusing.

Extreme ruggedness

Due to durable housing, waterproofness and functionality in the temperature range from -20 °C to +70 °C. Non-slip NBR Longlife rubber armouring resists oil, acid and weather influences.

BLUHORIZONS with Autobright technology - that's light protection for the eyes. Specially designed for all outdoor adventurers, the BLUHORIZONS not only fits in almost any pocket, is lightweight and also extremely robust. It is the world's first and only binocular to feature phototropic lenses.

After all, few things are more annoying than being blinded at the crucial moment when you're looking at the subject you want. The BLUHORIZONS with Autobright now puts a stop to this annoyance and offers long-lasting visual pleasure on every sunshine adventure. Without squinting your eyes and without being dazzled, you can watch the wide world in a permanently relaxed way.
