If someone has, say, 20/10 or 20/9 vision will they benefit from the magnification effects of, say, low-power binoculars or scopes the way average-sighted people do (or even better, with additive or partial multiplicative effects maybe?), or will those tools be of no (or lesser) use to them because their eyes already do what those tools' lenses and prisms do, rendering them redundant? If low-power magnification does benefit them more than the average person, will their better-than-average vision mean they also experience a greater benefit from higher magnification optical tools?
I'm only asking about tools focused on magnification of objects and not, say, corrective lenses for farsightedness/hyperopia that a person with above-average visual acuity might need.
Thanks!
