Human Eye Pixel Density
Explanation: Digital images consist of millions of tiny, tile-like elements. The smaller these elements (called pixels), the greater the resolution. A single megapixel is equivalent to one million pixels in an image.
If you know the width and height of an image, you can calculate the number of pixels obtained by your camera (by simply multiplying them). In addition, megapixels have nothing to do with the quality of the image. The quality depends on the exposure, focus, light, lens of the camera, etc.
Human Eye Megapixel Range
However, the human eye does not work like a digital camera. Clearly, you can distinguish two lines if they are at least 0.6 minutes apart, which means that the equivalent pixel size is 0.3 arc minutes. Now take a horizontal field of 120 degrees and a vertical plane of 60 degrees as the total view plane. Then the resolution of your eye would be:
120 * 120 * 60 * 60 / (0.3 * 0.3) = 576000000 pixels = 576 megapixels.
