I hope I am not misunderstanding the post below but just as a precaution let me say that "eye relief" has NOTHING to do with how much correction there is ["diopters"] or how "far" the binoculars will focus, etc. "Eye relief" is the distance from the ocular lens [the one closest to the eye] to the point where the image is formed. [If you take your binoculars to a strong light-source and hold them with their objective lenses toward the light source and place a piece of paper so that the light from the light source that comes out the ocular lenses falls on the paper, and then move the paper back and forth until the image on the paper is in sharp focus, the distance from the paper to the ocular lens is the amount of "eye relief."] LONG "eye relief" [19 mm or more; the more the better] will allow the eyeglasses wearer to see THE ENTIRE FIELD OF VIEW; short eye relief causes one wearing eyeglasses to see a considerably NARROWED field of view. - Bill *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
