Both of these make us feel awake and active. ![]() ![]() When it's bright outside, the body releases serotonin – also known as one of the "happy hormones" – and cortisol, a stress hormone. In daylight, the portion of blue light is relatively high, whereas it is significantly reduced in the evening. Hormones in the body regulate how a person feels as well as their sleep-wake cycle. Exposure to bright light and, in particular, the portion of blue light affects our hormonal balance. Ultraviolet light, for example, influences the production of vitamins. Scientific studies have confirmed the biological effect of light on our body. Light influences whether or not we are awake, focused, productive, and feel energized and healthy. Light does more than just help us see, it is also an important means of regulating our biological rhythms and affects our general well-being. damage to the retina caused by high-energy incident light. In particular blue-violet wavelengths between 380nm and 440nm are seen as potentially damaging and have been implicated as one of the possible causes of photoretinitis, i.e. The blue component of light between 380nm and 500nm is also known as high-energy visible (HEV) light. By way of contrast, ultraviolet light is almost entirely absorbed by the front part of the eye, and significantly less than 5% of it reaches as far as the retina. Although blue-violet light has less energy than ultraviolet light, it is almost entirely unfiltered as it passes through the eye and reaches the retina. However, visible blue-violet light also has the potential to cause damage to our eyes. That is why people typically take precautions to protect themselves from the sun, using items such as sunscreen or a pair of sunglasses. BLUE LIGHT FILTER GLASSES REFLECTION SKINThe light that reaches and enters the human eye is divided into visible light, comprising wavelengths from 380 to 780 nm, and non-visible light, which includes light in the ultraviolet range (UV light) and the infrared range (IR light).Įxperts have been aware for some time that UV light can potentially damage biological tissue, such as our skin and eyes. ![]()
