Blue light is a color in the visible light spectrum which falls within the 400-500nm range.

Blue light in the range of 400-450nm can cause eye damage such as macular degeneration. Blue and green light from 450-550nm has a direct effect on the brain's ability to secrete melatonin, with a lack of melatonin causing issues for us in both falling and staying asleep.

Today, we are surrounded by this harmful blue light from all artificial light sources. This includes computer screens, TVs, smart phones, tablets and conventional LED lighting in your home. While we refer to this harmful artificial light as 'blue light', this does not always mean the light you notice will appear visibly blue.

Most people are completely unaware that the sources of artificial blue light are everywhere; in today's modern world, you simply cannot escape it. All modern devices which have a light source will produce some amount of blue light even if it doesn't appear to look noticeably blue.

In fact, all artificial, electric-powered devices which produce a light source will emit blue light to varying degrees, even if it doesn't look blue.

The most common sources of artificial blue light include:

• Tablets such as iPads
• Smartphones
• Monitors from computers and laptops
• LED and plasma TV screens
• Fluorescent lighting in offices and stores
• Conventional LED lighting in houses
• The light inside your fridge

Getting sufficient quality sleep each night is essential for the health of our body and mind. We’re all familiar with the fatigue, irritability, and poor productivity the day after a late night or when we haven’t slept well. However, chronic lack of sleep has other negative health consequences.

When we are in a state of deep sleep, the body can rest, repair and heal. Sleep deprivation and poor sleep quality have been linked to high blood pressure, heart disease, memory loss, type-2 diabetes, and low-immunity. A chronic lack of sleep is also associated with increased production of the hunger hormone ghrelin and impaired insulin sensitivity. This results in poor blood sugar control, weight gain, difficulty losing weight despite dieting and exercising. No matter how well you eat or exercise, if you aren’t getting quality sleep none of this will matter and your health will suffer.

If you are working for prolonged periods of time on computer screens or under harsh artificial lighting during daytime hours, you are damaging your eyes from chronic exposure to harmful blue light.

Symptoms can manifest as digital eye strain, dry, itchy or irritated eyes, headaches and migraines, even loss of vision from macular degeneration.
