What Is Blue Light? The Electromagnetic 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.

Not every colour of light is the same. The blue wavelength is great 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. This makes blue light very difficult to escape.

Do We Need Blue Light Blocking Glasses? & Is Blue Light Safe?

Do we actually need Blue Light Blocking Glasses or is it a myth? Well the studies and evidence suggests yes, everyone requires Blue light Blocking Glasses.

Blue Light is mostly friendly, we say ‘mostly friendly’ as it has not been around long enough for centuries of research and we are only now noticing its somewhat of an indirect, silent assassin. It can affect your sleep and this can potentially flow on to cause diseases. Until the invention of man-made lighting, the sun was the major source of light, and people spent their afternoons in almost darkness. Now, in much of the world, afternoons are as bright as day, you can thank Thomas Edison for inventing the light bulb.

But, is all this light a double-edged sword? Is the human eyes, brain and body built for 14-16 hours of light? In the afternoon light alters the body’s biological clock otherwise known as the circadian rhythm, the effect is difficulty sleeping or poor sleep. We are slowly identifying through research that blue light may contribute to the causation of cancer, diabetes, heart disease, obesity and that’s not all. Poor sleep and blue light have been linked to moods, productivity, ability to handle life’s simple problems and there is a strong link to poor sleep and depression.
