Not all blue light is bad - some exposure is good for our health. Exposure to natural blue light from sunlight during the day helps us to stay alert, perform well and positively influences our mood.

Sunlight is the main source of blue light but there are also man-made sources. Fluorescent and LED lighting, flat-screen televisions, computers, smartphones and other digital devices all emit blue light. The amount of blue light emitted from these devices is small compared to sunlight levels.

As we spend increasing time on digital devices, this raises concern about possible long-term effects of blue light over-exposure on eye health. Blue light exposure from these artificial sources can disrupt the internal body clock, particularly in the evenings – tricking our brains into thinking it’s still daytime, with potential to disrupt sleep.

It does this by inhibiting the natural production of melatonin, a hormone in our bodies that regulates sleep.

Studies have shown that wearing blue light blocking lenses when you use digital devices will reduce this effect.

Over-exposure to artificially made blue light (even during the day) can also contribute to headaches and migraines, and dry or fatigue eyes leading to blurred vision and discomfort. This collection of symptoms is becoming known globally as Digital Eye Strain, or Computer Vision Syndrome.
