Belay Glasses Without Bending Your Neck!

EyeSend eliminates neck strain by allowing you to adjust your field of view using the optics in the glasses instead of the muscles in your neck. They are the first adjustable-view glasses on the market.

Current belay glasses only elevate your field of view by a fixed 60°. If you climb on cliffs steeper than this, you’re compensating by craning your neck. The EyeSend field of view is adjustable from a 60° slab to a 120° overhanging route. You can use this range of adjustment to maintain a neutral, pain-free neck position while belaying, regardless of the cliff angle.

EyeSend Belay Glasses Comparison

Three Fields of View

The EyeSend belay glasses have three view; through, over, and under.

    A Solid Fame Withstands Crag Use!

    EyeSend belay glasses have strong, lightweight, polycarbonate frame. The design maximizes peripheral view and there's grippy rubber inserts on the temples.

    Easy On, Easy Off!

    Neck strap avoids ears for easy on/off even when wearing a hat or helmet.

    An Awesome Case Design!

    EyeSend case is packed with features. It's got quick-close velcro and a solid shell lined with velvet pocket.

    In the Box

    The EyeSend belay glasses come with a Synthetic Leather EVA case and a field service kit.

      Belay Glasses 101

      Regular belay glasses have a fixed view of 60 degrees. The EyeSend belay glasses have rotating mirror that adjust from 60 to 120 degree.

      Belay glasses reflect the image of the climber twice. The first reflection is off the mirror-coated bottom of the prism. Like any mirror, this first reflection inverts the image of the climber. The image is reflected a second time off the top surface of the prism (due to total internal reflection), flipping the image back to normal.

      Regular belay glasses use a fixed prism and therefore have a view centered around 60° from horizontal. Rotating regular belay glasses on your head does nothing to change the angle of view as increased refraction offsets the rotation. EyeSend’s adjustable prism allows the belayer to change the angle of view by adjusting the bottom mirror angle.

      Designed and Built in the USA

      EyeSend glasses are designed and manufactured in Logan, UT, USA. Keeping the product as local as possible helps reduce the manufacturing carbon footprint and feeds local businesses.

      Patent Pending

      The EyeSend Adjustable-View Belay Glasses are patent pending.

      Solid Product

      So far, so good. The glasses are comfortable and easily adjustable. The hardshell case with the carabiner are a nice feature. Honestly, the product is very solid. If I had a complaint, it would be the price: it's a little steep, compared with some other belay glasses I saw on the internet.

      Solving a Real Problem!

      I can't get over how novel these glasses are ... the range of the adjustable view has worked at every crag I've tried. And I love the stout case. Such attention to detail. Well done!

      I love my new glasses. The engineering of the adjustable lenses is genius. These babies will give me extra years of belaying
