Tele Vue Optics Eyeguard Extender, twist-on style

Concept: Many of our eyepieces, such as DeLite, Delos, Nagler type 4, 55 Plössl, 41 Panoptic have adjustable height eyeguards to permit comfortable viewing with or without eyeglasses.

Other eyepieces such as 35 Panoptic, 27 Panoptic, 40 Plössl, 32 Plössl have long eye relief that is comfortable for eyeglass wearers, but the eye relief may be uncomfortably long for some users without eyeglasses.
