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 has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Moon face is a type of corticosteroid-induced lipodystrophy along with "buffalo hump", which in one study occurred in 47% of the 820 patients. Moon face is among the most frequently reported adverse events of systemic glucocorticoids, along with insomnia (58%), mood disturbances (50%), and hyperphagia (49%). [8]
