Down on the beach again and looked up. Every moment without glasses is breathtaking. Corneal replacement is now a common outpatient procedure that ranks up with miracles like a gift from you know who. Can see to 1000yds and even scope use is 100% clear.

Depth of field on the Human Mark I eyeball is not all that large.
And it varies with pupil size, so bright light improves depth of field.

For the moat part you can have the sites in focus, or the target in focus,, but not both at the same time.

For handguns, the Gunsite saying is "Front site. Front Site."
Keep the eye focused on the front site.
