These are white-light solar binoculars that provide a clear black-and-white image of the Sun. The Although it offers high magnification, the 20x50 model still boasts a wide enough field of view that you can see the complete solar disk without moving the binocular.

Fold them down for safe and effective use with your eyeglasses or keep them unfolded if you don’t wear glasses.
Carry your EclipSmart binocular with the comfortable included neck strap. The binocular also includes a protective padded nylon case for storage and transport, and protective eyepiece and objective lens covers.
