Outfitted with innovative technologies and designed for easy carrying, the Steiner Optics 10x42 BluHorizon Binoculars are ideal for the beach, trail, birding, or sightseeing around town.

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 and darken when you go outside into direct sunlight. By reducing the excessive light, the lenses improve color rendition, contrast, clarity, and resolution while also making your viewing experience more pleasurable and comfortable. This adaptive system is complemented by a generous angle of view and short minimum focus distance. The former helps to minimize the hand shake that is often experienced when holding high-power binoculars and which takes away from the experience, while the latter allows you to make detailed observations of small birds at feeders or insects on flowers.

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.
