Steiner's proprietary Autobright Lens Technology utilizes existing tech from the eyeglass industry to solve common problems—such as eyestrain, reduced contrast and clarity, and washed-out colors—when using magnified optics in extremely bright conditions. This photochromic adaptive system automatically dims the lenses in bright sunlight, much like popular transition eyeglass lenses that are clear when you're inside will darken when you go outside. By reducing the excessive light, the lenses improve color rendition, contrast, clarity, and resolution while also making your viewing experience more comfortable. This is complemented by a wide apparent angle of view that helps to minimize the hand shake that is often experienced when holding high-power binoculars and which takes away from the experience. Winged eyecups that block peripheral light from hitting your eyes further improve contrast and reduce distraction.
Their housing is made of a lightweight and impact-resistant polycarbonate material that is also temperature resistant—making them extremely durable over their lifetime of use. The chassis is wrapped in an oil-, petroleum-, and chemical-resistant synthetic nitrile-butadiene rubber (NBR) armor that offers improved grip security, especially in cold and wet weather. Standing just 4.5" tall and weighing under 11 ounces, the BluHorizon will easily fit most packs, pockets, or purse and won't burden you when you have to carry them around your neck all day.
