  2. Visual acuity - Wikipedia

    en.wikipedia.org/wiki/Visual_acuity

    The maximum angular resolution of the human eye is 28 arc seconds or 0.47 arc minutes; [23] this gives an angular resolution of 0.008 degrees, and at a distance of 1 km corresponds to 136 mm. This is equal to 0.94 arc minutes per line pair (one white and one black line), or 0.016 degrees.

  3. Optical resolution - Wikipedia

    en.wikipedia.org/wiki/Optical_resolution

    The human eye is a limiting feature of many systems, when the goal of the system is to present data to humans for processing. For example, in a security or air traffic control function, the display and work station must be constructed so that average humans can detect problems and direct corrective measures.

  4. Naked eye - Wikipedia

    en.wikipedia.org/wiki/Naked_eye

    Uranus, when discovered in 1781, was the first planet discovered using technology (a telescope) rather than being spotted by the naked eye. Theoretically, in a typical dark sky, the dark adapted human eye would see the about 5,600 stars brighter than +6 m [6] while in perfect dark sky conditions about 45,000 stars brighter than +8 m might be ...

    The human eye is a sensory organ in the visual system that reacts to visible ... rods respond to low intensity light and contribute to perception of low-resolution, ...

  6. Eye - Wikipedia

    The highest such number that the eye can resolve as stripes, or distinguish from a grey block, is then the measurement of visual acuity of the eye. For a human eye with excellent acuity, the maximum theoretical resolution is 50 CPD [43] (1.2 arcminute per line pair, or a 0.35 mm line pair, at 1 m).

    The key for working this out would be utilizing a technology called foveated rendering to track where a user's eyes are looking and ensure that only the area at the center of their vision is being ...

  8. Angular resolution - Wikipedia

    en.wikipedia.org/wiki/Angular_resolution

    Angular resolution describes the ability of any image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to distinguish small details of an object, thereby making it a major determinant of image resolution.

  9. Vision span - Wikipedia

    en.wikipedia.org/wiki/Vision_span

    The visual field of the human eye spans approximately 120 degrees of arc. [1] However, most of that arc is peripheral vision. The human eye has much greater resolution in the macula, where there is a higher density of cone cells. The macula has a diameter of about 16 degrees of the retina. [2]
