We spend a large part of day using our electronic devices, from TV's, tablets, smart phones, or laptops, whether it's at work, at home, or anywhere in between. We're continually connected and exposed to the potential harm of blue light.
Blue light is one of the shortest but highest energy wavelengths, ranging from 380nm to 500nm.

Using a digital screen just before bed can result in more tossing, turning and difficulty falling asleep.
Blue light (HEV - high energy visible) is part of the visible light spectrum found naturally in daylight hours from the sun or artificially from backlit digital devices. This can be broken down in to Blue-Violet and Blue-Turquoise light.
Naturally occurring blue-turquoise light helps regulate your sleep and wake cycles (known as circadian rhythm), boosts your alertness, mood and general well-being.
However, the increasing usage of backlit digital devices and excessive exposure to artificial blue light can have a negative affect by causing disruption to your circadian rhythm (by primarily suppressing the important sleep hormone, melatonin), digital related eye strain and headaches.
Ideally, we should try to reduce our exposure to blue light where possible, especially around bed time to ensure we get a great nights sleep. However, while this is not always possible there are some steps you can take:
Lenses such our BlueGuard lenses include a filter to actively block harmful blue-violet light. This also includes regular UV protection, scratch resistance and anti-reflective coatings.
If you're using a computer, tablet or phone in the evening, it's recommended to reduce the brightness to a minimum to reduce exposure to blue light. Many smart phones and tablets now also include a night shift or evening mode, this reduces brightness and adjusts the colour temperature to a warmer hue.
If you spend a lot of time using digital devices, we highly recommend giving your eyes regular breaks by focusing on different objects at various distances. A good excuse to go and make a cup of tea!
