HUMAN EYE RESOLUTION - ScienceNerds

What's the resolution of your mobile?

Well we all know our mobile screen resolution, after all, screen resolution and camera quality are the main features we see while purchasing new mobile, right?!

Why can we buy new mobile while the opposite one working satisfactorily and work is being done?!

the straightforward answer is often, the captivating innovation, we as an entire like to have redesigned innovation however the inquiry here is does it truly have any quite effect?

If you're purchasing a replacement mobile for an upgraded RAM or Memory, surely it makes a difference but what fascinates us more is display resolution 720p to 1080p and 4k.

up to what point does it truly has the effect to your eyes, I mean what is the most extreme limit up to which your eyes can see the distinctions in goals?

We have the biological camera called eyes, the resolution of human eyes is estimated to be 576 megapixels, meaning whenever you're clicking an image from your phone's 12 Mpx camera that picture is being seen by another 576 Mpx camera!

But the very fact to be noticed here is your eyes can cover 180° at a time from a static head position(Eyes can move in possible directions), but the focused part is merely 120° and therefore the left and right eyes cover 30° each on respective sides. the sector of view is illustrated within the below figure.

1 megapixel = 1 million pixels

what factor estimates the human eye resolution?

576 million pixels placed during an outsized enough display that completely covers the human eye field at a distance where eyes can't differentiate between individual pixels.

Even though eyes can cover 180° of view field while reading the view is concentrated on a specific point and therefore the surrounding area being visible will remain unfocused, we call this the daylight vision.

Thus in the event, we create a computerized picture from our eye vision, its quality is finding a workable pace simply like the picture clicked from 5Mpx camera.

The extreme contrast within the goals which our eyes can see depends on the components: 
  • Size of the screen
  • Resolution
  • Typical viewing distance

The more number of pixels implies the upper goals, which provides the office to catch and show progressively visual data.



PPI - Pixel per Inch is a crucial factor,


you can calculate the PPI of your mobile screen, visit the subsequent link -
