The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition.
Infant sleep is an act of sleeping by an infant or a newborn. It differs significantly from sleep during adulthood. [1] [2] [3] Unlike in adults, sleep early in infancy initially does not follow a circadian rhythm. Infant sleep also appears to have two main modes - active, associated with movement, and quiet, associated with stillness ...

Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which in artificial narrowband form has a number of proven negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related ...

Landing lights are usually extinguished in cruise flight, especially if atmospheric conditions are likely to make the lights reflect or glare back into the eyes of the pilots.
