Our Audubon Campers, my five year-old, and myself all use Eagle Optics 8 x 42 Rangers. My son’s doing so well with them I think I’ll give mine to him for Christmas and get something different for myself. He used them to find and identify a distant mountain bluebird for me in the Badlands during our recent road trip. Most starter kids binocs are utter junk.

If that distance can not be made closer (or squoze), as is often the case on many "starter" binoculars, it won't matter a whole lot what the field of view or exit pupil is because the big, beautiful sweet spot needed for a clear focused image will not be attainable. I learned several years ago that in their infancy binoculars were designed for men (mostly hunters) and these bins will probably fall into the IPD (interpupillary distance) range of 54-68 mm whereas because of smaller stature children and most women have an IPD of 41-55 mm. This is evident when being fitted for glasses the optometrist will measure this distance so that your glasses focus as intended! The squoze factor is especially noticeable when using binoculars with that sort of rocker arm assembly. The rocker-arm dealy prevents them from being squozed.
