The eye relief of an optical instrument (such as a telescope, a microscope, or binoculars) is the distance from the last surface of an eyepiece within which the user's eye can obtain the full viewing angle. If a viewer's eye is outside this distance, a reduced field of view will be obtained. The calculation of eye relief is complex, though ...
Binoculars may have eye relief ranging from a few millimeters to 25 mm or more. Eye relief can be particularly important for eyeglasses wearers. The eye of an eyeglasses wearer is typically farther from the eye piece which necessitates a longer eye relief in order to avoid vignetting and, in the extreme cases, to conserve the entire field of view.
These binoculars, which have been on the market for high-quality compact binoculars for a long time, had the optical parameters 8×20 and 10×25. The "B" designation added to updated models means that there is sufficient eye relief for eyeglasses [Brille in German] wearers. The Trinovid series were supplemented in 2004 by the Ultravid series ...
Eye relief typically ranges from about 2 mm to 20 mm, depending on the construction of the eyepiece. Long focal-length eyepieces usually have ample eye relief, but short focal-length eyepieces are more problematic. Until recently, and still quite commonly, eyepieces of a short-focal length have had a short eye relief.
Prism sights are a type of telescopic sight with similar features and limitations. Most prism sights use roof prisms commonly seen in compact binoculars and spotting scopes. The reticle is etched onto one of the internal reflective surface of the prism, making it easy to illuminate the reticle from the back of the prism even when active ...
The longer the focal length of the eyepiece, the greater the eye relief. Typical telescopic sights may have eye relief ranging from 25 mm (0.98 in) to over 100 mm (3.9 in), but telescopic sights intended for scout rifles or handguns need much longer eye relief to present a non-vignetted image.
