There was a day when you had to search carefully for a
binocular that was suitable for use with eyeglasses. In the "good old days" those of us with "four eyes" had a limited selection when shopping for
binoculars. Fortunately, the situation has reversed itself and, now, binoculars with enough eye relief for use with
eyeglasses actually outnumber those that do not have the requisite
eye relief of 15mm or more. Maybe it's because the manufacturers are just being nice to we birders who wear glasses. Okay, it's more likely the binocular manufacturers realize that the majority of their customers wear glasses, some, or all, of the time.
