The Zeiss Replacement Longer Eyecup for Conquest HD 42mm Bino is an alternative to the eye cup that accompanies the original binocular. A broken eye cup isn't worth fiddling with, so get yours replaced ASAP if you need it! The cost is nominal compared to the binocular and it will save you a lot of headaches in the long term. These also fit the 32mm Conquest HD binoculars.
