What is Blue light and how it affects eyes?

Blue light is that part of the spectrum of visible light that has the shortest wavelengths and has the maximum energy, between 400 to 500 nanometers. Our corneas and lens block the reach of our retinas (the back of our eyes) from UV rays. Our eyes do not, however, block blue light well. In reality, through these mechanisms, blue light passes through and enters the retina. With blue light sensitivity, the possibility of macular degeneration, which can lead to artificial eye pressure, can be increased.

·        It can destroy retina cells

·         This can impact our wake/sleep cycle.

How it affects on eyes?

Blue light is everywhere-we get continuous exposure from the sun, computer screens, laptop, and tablets of blue light. And our body clocks may be influenced by this. Blue light is connected with our brain as daylight, but if you are exposed to blue light for long periods of time at night, it will make it hard for you to sleep at night and wake up in the morning.

There is really no conclusive evidence about the precise level of blue light you may be exposed to until the side effects occur, however, there may be some significant side effects from over-exposure to blue light. Among these side effects are headaches, lack of sleep, and disorientation.
