Resolution of an eye according to quick google search seems to be 324 megapixels.

That number is way too high considering that the fovea only subtends about one degree of visual field.

Or are you talking about a stitched image due to saccade?

tbh I didn't even read the article, it just popped right out in google, when checking it I found this

How many pixels are needed to match the resolution of the human eye? Each pixel must appear no larger than 0.3 arc-minute. Consider a 20 x 13.3-inch print viewed at 20 inches. The Print subtends an angle of 53 x 35.3 degrees, thus requiring 53*60/.3 = 10600 x 35*60/.3 = 7000 pixels, for a total of ~74 megapixels to show detail at the limits of human visual acuity.

And then in different article they say it's only 7 megapixels.. so I guess nobody knows exactly

It sounds like the key differences are not a lack of knowledge, but in the way the question is parsed.
