Is the Human eye capable to see in 4K?

human eye resolution

When the resolution of the human eye is in question, it is important to understand that there’s a difference between pixels and resolution. When looking at HD, or 4K TVs, the higher you go, the higher is the resolution, or the total number of pixels. Pixels are the individual points of light that make up a digital picture. For example, an 4K TV has 8.3 million pixels.

However, in human vision, eyes do not contain pixels. The closest comparison would be the rods and cones in your eyes that help you see. What’s more, what you resolve is the picture you can put together with your eyes and brain, not what necessarily exists in reality.

So, what is the resolution of the human eye?

Considering the human eye doesn’t see in pixels at all, it’s very hard to compare them to a digital display. But, if you could compare the two, how many pixels would the human eye likely have? Some complex math got to 576 megapixels. 576 megapixels are roughly 576,000,000 individual pixels, so at first glance, it would seem that we could see way more than a 4K TV has to offer. But it’s not that simple. For instance, we see in 576 megapixels definition when our eyes are moving, but a single glance would only be about 5-15 megapixels.

If you’re wondering if your potentially extreme high-definition 576-megapixel eyes can see more than a 4K TV has to offer, consider this experiment: think of when you are at the beach. If you look down at the sand closest to you, you can easily count the individual grains, right? But the farther you look, it becomes the more difficult or even impossible. Taking into account that distance plays an enormous role in our resolution. Since there are so many variables that come into play, there is no clear yes or no answer to “can we see in 4K?” So, in theory, at some distance, we can say – yes, it is possible.
