Night Vision

Night vision

Night vision is the ability to see in low-light conditions, either naturally with scotopic vision or through a night-vision device. Night vision requires both sufficient spectral range and sufficient intensity range. Humans have poor night vision compared to many animals such as cats, dogs, foxes and rabbits, in part because the human eye lacks a tapetum lucidum, tissue behind the retina that reflects light back through the retina thus increasing the light available to the photoreceptors.

Night Vision (Bruce Cockburn album)

Night Vision is the fourth studio album by Canadian singer-songwriter Bruce Cockburn released domestically on True North Records. The album earned Cockburn's first Canadian gold record award in 1979. It was the first full album that Cockburn recorded with a band. The album saw Cockburn incorporate elements of jazz guitar into his music.

Night

Night, or nighttime, is the period of darkness when the Sun is below the horizon. Daylight illuminates one side of Earth, leaving the other in darkness. The opposite of nighttime is daytime. Earth's rotation causes the appearance of sunrise and sunset. Moonlight, airglow, starlight, and light pollution dimly illuminate night. The duration of day, night, and twilight varies depending on the time of year and the observer's latitude.

Midnight blue

Midnight blue is a dark shade of blue named for its resemblance to the apparently blue color of a moonlit night sky around a full moon. Midnight blue is identifiably blue to the eye in sunlight or full-spectrum light, but can appear black under certain more limited spectra sometimes found in artificial lighting. It is similar to navy, which is also a dark blue.
