Spending a considerable amount of time on electronic devices has become a norm in today\u2019s post covid era. Electronic devices including your laptop, phones and tablets emit blue light which is concerning because the blue light can be bad for your eyes. <\/p>\n
Energy travels in wave form. Each form of energy has a particular wavelength. Energy with wavelength 380-720nm is visible to the human eye and is called visible light spectrum. Energy with wavelength higher than 720 nm is called ultraviolet light also known as blue light.<\/p>\n
UV light is naturally present in sunlight but is also produced by digital screens such as TV, computers, laptops, smartphones, tablets, and LED lighting. <\/p>\n
UV rays present in sunlight is the signal for the human body to be awake. It helps to maintain our normal sleep cycle. When the sun goes down, the signals to the brain are automatically cut off, resulting in production of the sleep hormone also known as melatonin, which slowly helps you to drift off to sleep.<\/p>\n
When we use phones late at night, it signals the brain to hold the release of melatonin, therefore we feel more active and alert and unable to fall asleep. This \u00a0disturbs the sleep cycle and worsens the quality of sleep. Sleep deprivation can be very detrimental to our mental and physical health.<\/p>\n
According to studies, these are the effects of blue light on our eyes.<\/p>\n
