The Bushnell Permafocus 12x50s do not show as much detail as a pair of 7x35 binoculars for objects less than 100 yards away because the 12x50s are not in good focus at 100 yards, and uselss at less than 50 yards. Bushnell deserves a "booo-hisss" for hiding this information from customers. The minimum usable distance probably varies with the ability of the user's eye to focus (this decreases with age) but mine are probably about average. Also, the inside instructions indicate Permafocus binocs are good at less than 100 ft, depending on the model. This is not true for the 12x50s. Most inexpensive 7x35s will give a better view at 300 feet and less.
But if objects are over 200 yards, the 12x50s are in focus and flawless as far as i can tell. I can easily recognize people at 700 yards. I can read license plates at 350 yards (it helps if the binoculars are resting on something to prevent vibration).
Without a support, there's probably too much shaking for 16x50 binocs to do much better than 12x50s.
The eyepiece rubber does not stay rolled back (if you try to use them with glasses) for more than 1 second, so you can't wear glasses while using them, but as with other binoculars, you do not need to wear your glasses. I don't know the science behind it, but whether or not you wear glasses does not seem to make a difference with the Permafocus. The rubber around the eyepieces cannot be removed unless it's cut.
In summary, the normal Bushnell 12x50s are probably much better than the Bushnell Permafocus 12x50s because they can be used at much shorter distances and focusing on objects greater than 200 yards should not be too much of a pain. These 12x50s are no good unless your typical viewing distance is greater than 150 yards and you don't plan to use them on less than about 60 yards. I'm returning them due to "manufacturer's defect".
But concerning the Permafocus idea: I love my old pair of "total focus" 7x35's for bird-watching and carrying in the car. Being free of focus is a different experience almost as big as going from monocular to binocular. But you need a pair that can focus down to 50 yards.
