18 mm eye relief – why the BD 10x25 is the compact binocular for spectacle wearers
Most compact binoculars offer 12–15 mm eye relief – not enough to see the full field with spectacles. The KOWA BD 10x25 DCF delivers 18 mm, providing enough clearance even for progressive lenses or thick frames without vignetting. Twist-up eyecups adapt flexibly: down for spectacle wearers, up for those without. Thanks to C3 prism coating, the image stays bright and crisp despite the compact 25 mm objective.
C3 prisms and Eco-Glass – KOWA optics in pocket size
KOWA fits the BD 10x25 DCF with C3-coated roof prisms – a triple coating that noticeably boosts light transmission over single-coated prisms. Additionally, KOWA uses lead-free Eco-Glass that delivers the same optical performance as conventional glass while being more eco-friendly to produce. Fully multi-coated surfaces on all glass-air interfaces ensure bright, colour-accurate images – even in early dusk.
Waterproof and rubber-armoured – a pocket binocular for any weather
The BD 10x25 DCF is fully waterproof and nitrogen-purged. The optics will not fog when you step from an air-conditioned car into summer heat or observe in drizzle. Rubber armouring protects against scratches and provides a secure grip with wet hands. The 1.8 m close focus suits butterflies and wildflowers along the trail.
