Second part: based on tech like the eyeband, my thought is that the tech doesn't exist to have more than the natural 'brain focus'.
It seems to me there are three kinds of focus that would be topical here.
1. Concentration: the ability to usefully do something with more than one simultaneous stimulus.
2. Foveal: of or pertaining to increased visual acuity in the center of the visual field
3. Optical: the focusing of light into a distinct image.
The ability to usefully concentrate on more than one visual stimulus isn't something a smartlink does, or is intended to do. You could argue that there are some augmentations that might serve that purpose, but that's beyond the scope of our inquiry for the moment.
I have
no idea what cybereyes would do to foveal focus; we talk a lot about sensory overload and such, but the fact is that the brain is very plastic, and it'll adjust to a broad spectrum of alterations.* That said, I don't think foveal focus matters much in this case, unless you're trying to target two individual targets not within the center of your vision, and as you've pointed out, that's hard irrespective of the smartlink.
Optically, I don't see where it would be a problem for people with cybereyes, because the signal from the image link is going to be dropped into the data stream long after the optical data, anyway. So you should be able to have a set of razor-sharp dots, or crosshairs, or fuzzy slippers, in whatever colors, blinking whatever pattern, dancing whatever polka you'd like, as far as that goes. As far as shades and goggles go, well, that's an optical focus issue, but that's the same optical focus issue you'd have with one smartlink, and the same optical focus issue you have with scopes today.

But, it shouldn't matter for this question.
I'll confess I'm not certain how any of this could matter at all. The smartlink, in my understanding, is nothing but a ballistic computer and a rangefinder [and other senses if you'd like; there's no reason not to allow such a thing], which figures out where, if you pulled the trigger right now, a bullet would end up, like a laser pointer with a rangefinder and a servo on it, constantly adjusting trigonometry. And only you can see it. Does everyone agree that's what the experience is like? I read some stuff upthread about cameras and two video feeds, so I'm not sure my understanding of the hardware is the same as everyone else's.
*Build yourself a set of goggles with cameras on them, but with the image inverted, so that when you look through the goggles, everything you see is upside-down. Blacken the windows in your bedroom, and see nothing without the goggles for, say, a week or two. You'll find very quickly - like, crazy quickly - that you'll stop noticing the goggles, and your view won't be inverted, because [as I'm sure you know] the goggles are just
undoing the brain's inversion of our visual input. Take the goggles off after a couple of weeks, and you'll be again stuck with inverted vision, until the brain re-orients itself. My point being, I don't have any difficulty with the concept that, with cybereyes not having a foveal acuity increase, the human mind could deal with having no "periphery," and would do just fine. I, for one, wouldn't mind being able to read without
looking right the hell at things. Anyway.
