Binocular Eyecups
The very best purpose of Binocular Eyecups and just what do they suggest to me?
Right now there are only 2 reasons manufacturers supply Eyecups for goggles. One is to provide "shade/cover" between typically the focal lens regarding the binocular eyepiece and the attention and two, to realize a "stand-off" from typically the eye to typically the focal lens or eyepiece in the binoculars.
