What does it mean when scientists say “an eagle can see a rabbit in a field from a mile away”. Is their vision automatically more zoomed in? Do they have better than 20/20 vision? Is their vision just clearer?

Answer 1

After lasik surgery, I had 20/10 vision in both eyes.

That means I can resolve images at 20 feet what you need to stand 10 feet from to figure out.

I don’t see zoomed in. It’s just more detailed. Like a higher resolution display.
