What Is Blue Light? The Electromagnetic Spectrum

What Is Blue Light - Electro Magnetic Spectrum

All light, including blue light, is made up of electromagnetic particles that travel through the air to our body in waves. These waves emit energy and depending on the colour, the strength and range of the light can differ. A shorter wavelength is associated with higher energy levels. The unit of measure for light is nanometres (nm) with 1 nanometre equalling just 1 billionth of a meter. Grouped up these items create the electromagnetic spectrum, but only some of these are visible to us.Blue Light & The Electro Magnetic Spectrum.

 Blue Light & The Eye

Science has proven the human eye is especially sensitive to light inside the ‘visible light’ spectrum. Visible light consists of these colours: violet, indigo, blue, green, yellow, orange and red.The Visible Light Spectrum from 700nm to 400nm, Red, Orange, Yellow, Green, Blue, Indigo & Violet

Blue light has one of the shortest wavelengths and produces a much higher amount of energy. Many studies suggest exposure to the blue light spectrum over time causes severe long-term damage to your eyes and can affect other areas of our brains.

The blue wavelength is excellent during the day as it increases attention, improves reaction times, and lifts mood, but it is the most troublesome wavelength at night. Many of us are surrounded by screens everywhere, from the second we leave for work, school, in the car to the last minutes of awake time before (trying) to go to sleep. Overall it makes blue light very difficult to escape.
