It’s hard for a day to pass without the use of an electronic device. Whether it’s a computer, mobile or tablet, we’ve never been more reliant on technology and whilst these devices are seen as vital to modern living, there have been many reports of the negative impacts our dependence on these devices can have on our health.
You may be aware that over exposure to electronic devices can have a detrimental impact on our eye health. So, whilst you are certainly not alone in staying up for hours scrolling through social media, or glued to your latest favourite TV show, here’s why your eyes might not be thanking you for it:
Blue light, which is also known as high-energy visible (HEV) light, is one of the causes of digital eye strain. HEV comes in two forms – artificial (from mobile phones, computer screens, led lights etc.) and natural (from the sun).
Natural blue light has some beneficial effects:
However, blue light also has some negative effects:
Let’s take a deeper dive into the most common effect of artificial blue light – digital eye fatigue. It is estimated that 50-90% of people who work on computers have reported digital eye fatigue symptoms. Digital eye fatigue (also known as asthenopia) has a variety of side effects including dry eyes, difficulty focusing, headache, tiredness and light sensitivity. Eye fatigue is linked to the prolonged use of any technology permitting light such as TVs, laptop/computer screens, mobile phones and tablets, and the distance the user is from the device in question.
Another condition which is associated with the use of technology is myopia, and this is caused by the proximity of the device to our eyes. Myopia is another name for short-sightedness. Myopia is an eye condition what causes objects in the distance to become blurry. In the UK alone, it is possible that it is affecting up to 1 in 3 people and this number is expected to rise.
In 2010, approximately 28.3% of the world’s population (or 2 billion people!) were suffering from myopia. It is predicted that by 2050, a huge 49.8% (or 4.8 billon people) will be suffering from the condition. According to an article referenced in the Ophthalmology journal, the sudden decline in vision is related to the increased use of screens on smartphones and computer monitors.
