You have a very basic misunderstanding of how vision works. Visual acuity has nothing to do with how FAR your eye can see...
"Visual acuity refers to the ability to resolve two separated points or lines, but there are other measures of the ability of the visual system to discern spatial differences."
"Visual acuity depends upon how accurately light is focused on the retina, the integrity of the eye's neural elements, and the interpretative faculty of the brain.[23] "Normal" visual acuity (in central, i.e. foveal vision) is frequently considered to be what was defined by Hermann Snellen as the ability to recognize an optotype when it subtended 5 minutes of arc, that is Snellen's chart 6/6 meter, 20/20 feet, 1.00 decimal or 0.0 logMAR."
As one might have guessed from the word "acuity", it is a measurement of how accurate your eyes are.
Your definition of Diffraction is close enough to reality, but since you wanted to get technical, here it is defined by wikipedia:
"Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength."
Your next statement is where you really start to lose me: "Your eye cannot see forever". You understand your eye isn't reaching out and sensing things, right? Light is emitted or reflected by something, which then strikes your retina, and is interpreted by the brain. That's a rather simplified explanation, but you can read further here, and look at this picture of an eye. Your eye can literally only see what is physically touching it.
Now since light can travel quite literally forever, and your eye senses light, you can see as far as light has bothered to travel and hit your retina. I can look out my window and see the Andromeda galaxy with the naked eye, yet it's located 2.6 million light-years from Earth.
You then claim that "it's easy to flippantly dismiss flat earth". There's really nothing to be dismissed. Your youtube videos are excellent examples of persuasion, and not examples of science. If the earth is flat, then basically all the rest of science is wrong. They are incompatible and mutually exclusive ideas. Somehow you people think NASA and satellites are how we know the earth is round. You lack a very basic understanding of the entire body of all scientific work.
I would strongly recommend you acquaint yourself with HISTORY, and therefore how we slowly discovered, independently and the entire world over, that the earth was round (it's not a perfect sphere, but it is round).
A great starting point, if you honestly have a real interest in anything beyond dogma, is Bill Bryson's A Short History of Nearly Everything.

If nothing else it will point you towards the top 50 scientist/mathmeticians in the last 2500 years that really shaped what we know today.
I think i got trolled....
