WebThe human eye is an incredible tool, capable of seeing a vast range of light from the brightest sun to the faintest star. Our eyes can also adjust to different levels of brightness, allowing us to see in both bright and dark environments. This ability to adjust is called dynamic range. HUman eye dynamic range is much wider than that of a camera. WebA dividing line between near and mid peripheral vision at 30° radius can be based on several features of visual performance. Visual acuity declines systematically up to 30° eccentricity: At 2°, acuity is half the foveal value, …
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz. These boundaries are not sharply defined and may vary per individual.
