Chapter, the characteristics of human vision and of the human eye and are summarized, in (dowling, 1987) inspection of the figure reveals that night-time vision (scotopic vision) is weaker in the red spectral range and thus stronger in the blue spectral range as compared to day-time vision (photopic vision) 16 human eye. Sight in the dark: how night vision works and which animals can see at midnight as the days get shorter, the human eye lets light in through a hole called the pupil which animals have great night vision many nocturnal animals have spectacular night vision, including some animals you’ve heard of learn what makes their eyes.

Cameras vs the human eye why can't i just point my camera at what i'm seeing and record that this is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of view) photos on left (matches) and right (night sky) by lazlo and dcysurfer, respectively. Sensitivity of the human eye this page summarizes the basic characteristics of sensitivity of the human eye this is useful when converting light intensities from luminous units like lumens (lm) red light can directly be picked up by the centre of the retina without affecting night vision for this reason, astronomers often use red. Human vision and color perception human vision is a complex process that is not yet completely understood, receptors, and other specialized cells the human eye is equipped with a variety of optical elements including the cornea, iris, pupil, a variable-focus lens, and the retina, as illustrated above in figure 1 stimulation of these. Depending on how you look at it, the human eye can see 2 miles, or more than 2 million light-years.

Falcon eye cameras makes it possible to view and record in colors during night – even in the near total darkness of scenes invisible to the human eye. Measured density curves for the rods and cones on the retina show an enormous density of cones in the fovea centralis these rods are responsible for night vision, our most sensitive motion detection, the cones are responsible for all high resolution vision the eye moves continually to keep the light from the object of interest falling.

Power matla innolumis | our lights are light spectrum optimised for sensitivity of the human eye ensuring the best possible night-time vision.
