'You may imagine “flicker” as being a full on/off situation, similar to strobe lighting,' Marianna says, 'but in fact, any fluctuation in brightness of light is classified as flicker.' In most cases, flickering light is in fact invisible to the naked eye. Now I know what you're thinking 'but my lights don't flicker!' Surely if you can't see your light bulbs or screen flickering, you must be fine, right? 'Even more alarming when you consider the increased amount of time our children are spending on digital screens at a time when their bodies and minds are constantly growing, unfortunately making them much more susceptible to the problems caused by artificial light flicker than adults.' How can you capture flicker that's invisible to the naked eye? 'Prolonged exposure can lead to health issues such as headaches, fatigue, blurred vision, vertigo, panic attacks and even some chronic neurological conditions,' Marianna explains. In both cases, flickering light is also to blame. We all know that cutting out screen time before better can help you sleep better, too. This is especially common for those who work in office jobs, who may feel particularly fatigued after a day at work despite being sat down for the majority of the day. If you've ever found yourself with a headache or eye strain after being sat in front of the computer for too long (let's face it, we've all been there), flickering lights are almost certainly the culprit. 'When exposed to flickering light, our eyes have to rapidly adjust to the changing light output which places an unnecessary stress on our eye muscles.' 'Studies have shown that flickering light bulbs and the LED lighting flicker emitted from digital screens can cause numerous physical health problems and measurable physiological changes,' biophilic interior designer Marianna Popejoy of The Wooden Hill (opens in new tab) tells us.
