Blue light is made up of two parts – the turquoise part has many health benefits.
BENEFITS OF TURQUOISE BLUE LIGHT
Blue-Turquoise light can be beneficial to our health. It regulates the circadian rhythm (our internal ‘body clock’), which controls our sleep-wake cycle. So it is essential to a restful night’s sleep. It can also boost brain activity, improving memory, mood, alertness and mental performance.
HARMFUL VIOLET LIGHT
As with UV rays, overexposure to blue-violet light can be harmful to the eyes.
It can damage the retina, and potentially increase the risk of age-related macular degeneration (AMD), cataracts and photokeratitis (sunburned cornea) – which can lead to temporary blindness.
