What is the megapixel of the human eye?

The human eye doesn't work the same way as a camera, so it doesn't have a direct "megapixel" equivalent. However, scientists and researchers have tried to approximate the resolution of the human eye by comparing it to digital cameras.
Estimates of Human Eye Resolution:
- Field of View: The human eye has a very wide field of view, approximately 120° to 200° (depending on the individual and whether you include peripheral vision).
-
Resolution: The sharpest part of your vision, called the fovea (which is the center of your retina), can resolve fine details. In terms of resolution:
- It is often estimated that the human eye can resolve around 576 megapixels if you consider the detail it can detect across its entire field of view. This number is based on the idea that the eye can discern a large number of pixels across its broad field of vision.
More Practical Consideration:
- Central Vision (Foveal Vision): In the central focus area, the eye's resolution is much sharper, and it’s similar to about 60-100 megapixels.
- Peripheral Vision: The peripheral vision (around the edges of the field of view) is much less detailed. The ability to distinguish fine detail drops off sharply the further out you look from the center of your field of view.
Comparison to Cameras:
- Camera Sensors: Cameras can capture all the details in a specific frame, but the human eye continuously adapts and processes information, so it doesn't "capture" images in the same way.
- Dynamic Adjustment: Unlike cameras, which capture static images, the human eye constantly adjusts, so while it can detect a broad range of light and color, it doesn't "store" a full frame as a digital camera would.
Summary:
- The human eye doesn't have a fixed megapixel rating because it works dynamically. However, if we were to approximate it, it could be thought of as having a resolution equivalent to around 576 megapixels when considering the entire field of vision, with sharp focus around 60-100 MP in the central part.
