Human Eye is equal to 576 megapixels camera and it is amazing and immersive when we compare it to the 10 megapixel or 12 megapixels cameras in our smart phones.
According to scientist and photographer Dr. Roger Clark, the maximum resolution possible for a human eye is 576 megapixels. This is one of the wondering facts about a human eye.
The 576 megapixel view by an human eye means that one is watching an 8K TV.

In this article you can read about resolution details of human eye and a resolution of a digital image. For more wondering facts about human eye, read this article to the end.
What is Image Resolution?
In modern science, a pixel is the smallest unit of an electronic or digital image. Similarly, the resolution of an image is based on the number of pixels that exist in a digital image.
Consequently, the quality of a digital image is directly proportional to the number of pixels in that image. The more number of pixels in a digital image are, better quality of image will be.
The quality of a digital image also depends upon the distance from where the digital image is being looked. Far closer view, may deteriorate the quality of the digital image as it will not cover all the pixels.
Human Vision vs Digital Image
When, we talk about image resolution, or image recognition by human eye, things become very different and respective in comparison to resolution of a digital image and its recognition.
A fundamental difference is that a digital camera snaps a single image in one click while, a human eye constantly capturing images and send these to the brain.

Another difference is that camera captures every minute detail in a digital image whereas, a human eye focuses more on a few parts and makes a few other areas blur. Human eye also have to tackle the ‘blind spot’ issue.
The final image is only produced by the human brain as eye just send random visuals to the brain and then brain decides that what information is useful and what is not.
What is resolution of Human Eye?
Roger Clark is a famous scientist and a photographer. He has reported that a full visual frame of human can capture a maximum density of 576 megapixels. However, a single glance in routine just captures 5-15 megapixels as it is required.
In other words, 576 megapixels are equivalent to 5.76 billion pixels. The light, distance, brain focus and a few other factors decide that up to what depth of an image is required and then respective data is captured by an human eye, accordingly.
In addition to this selective resolution of an human eye. human eyes just move about and capture a lots of visual information and then its brain responsibility to finalize the detailed image.
Limitations of Human Eye
Human Eye is equal to 576 megapixels camera however a human eye can not digest all the visual information. So, an image of a 576-pixel screen can be over-detailed for a human brain to interpret.
A health human eye is good to get 7 mega pixels in our fovea range; it’s been roughly estimated that rest of our field of view would only need 1 megapixel more information to render an image.
