The human eye is often estimated to have a resolution equivalent to about 576 megapixels. This estimate considers the spatial detail that would be required in an image to represent what the human eye can see across its entire field of view, roughly 120 degrees. However, this is not a simple pixel-by- pixel capture like a camera; the eye continuously moves and the brain processes information in a way that effectively assembles a high-resolution image over time. In a single glance, the resolution is significantly lower, around 5 to 15 megapixels. The central part of the vision (the fovea) is where the highest detail is perceived, roughly equivalent to 7 megapixels within that area alone. In summary:

• The total field of view resolution is about 576 megapixels.
• Single glance resolution is about 5-15 megapixels.
• The fovea (central vision) covers about 7 megapixels.
• The eye-brain system combines information dynamically, not static like a camera sensor.

This 576 megapixel figure comes from calculations based on angles and the resolving power of human vision, considering visual acuity limits and field of view.
