Flexible rubber eyeguards reduce ambient light and glare reflections, thus protecting your dark adaptation, while providing the viewer with comfort for maximum visual effectiveness. Eyeguards assure proper eye-to-lens positioning and also protect the optical surface from grime and oil. The eyeguards are made of flexible, yet strong rubber so they will stretch a bit beyond the nominal diameter noted below to fit over many other eyepieces. However, note that this style is thicker and of a more rigid design that does not offer the same stretching or folding flexibility as some of the other eyeguards we offer.
Please note that these are sold individually.
Nominal diameter ~28.4mm (unstretched). Height = 13mm. From Agena's 1.25" UWA eyepieces. As a reference, the diameter of the barrel extension this eyeguard sits over on the UWA eyepiece is 32mm. Cannot be folded down. Made in China.

It's pretty much the only choice.Pros:
Strong Construction,CompactCons: Comments:
This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
