BoliOptics Microscope Eye Guards, 34mm Rubber Eye Cups, Foldable (Pair) SZ05013911

I needed to replace the eyecups on the eyepieces for my microscope. The old rubber eyecups had cracked. I was a little worried about how these would fit on my Olympus eyepieces. There is a groove on the Olympus WK 10X/20L eyepieces that held the old eyecups in place. These eyecups have a similar ridge that fits into the groove. The groove on my eyepieces is a little wider than the ridge on these but they still fit well. They are snug but not too tight and the length of them is nearly identical to the original ones.

I bought Orion 2x54 Ultra Wide Angle Binoculars, but they did not include any eye guards on the eyepieces. The eyepieces without cups are hard to hold evenly in front of the eyes, and the bare metal is a serious hazard to glasses. These eye guards worked perfectly to correct the deficiency on these binoculars.

Pretty much same as original piece that the company that makes my spotting scope sent as a replacement!

37mm faces the eye piece and 34mm faces your face. Even the lens caps fit perfectly. 👍
