What is digital eye strain?
In today’s digitalised world, problems with digital eyestrain have started to show signs of sharp increase. But what is digital eyestrain? Why is digital eyestrain now such an issue and what does it mean to suffer from digital eyestrain?
Digital eyestrain is also referred to as computer vision syndrome is a set of vision related problems that result from extensive use of a computer, smart phone, or tablet. The majority of people that use a computer will at some point experience digital eye strain. Symptoms of digital eyestrain seems to increase with the time spent at a computer. The longer one spends at a computer or on their phone the more severe the symptoms of digital eyestrain.
What causes digital eyestrain?
Whilst there may be many factors that leads to digital eyestrain blue light seems to be the biggest culprit. Blue light is high energy visible (HEV) light which is found in large quantities in digital devices such as your smart phone, laptop and tablet. Blue light from screens can decrease contrast which is the main cause of digital eyestrain. Fatigue caused by excessive blue light exposure after sunset disrupting your circadian rhythm and sleep can also lead to digital eyestrain. Dim lighting which is still blue light can also intensify the symptoms of digital eyestrain.
Blue light, given how high energy it is may also cause some cellular damage in the eyes. After a long day working on your computer (which emits lots of blue light), the cumulative damage caused by this excessive blue light exposure can lead to digital eyestrain.
Flickering blue light is also a major cause of digital eyestrain. Almost all LEDs flicker. This flickering blue light can be found in computer screens, smart phones, tablets but also in office and house lighting. Flickering light is due to the AC current and is an energy saving tactic. This is all very well but this flickering effect of blue light also leads to digital eyestrain.
There are workarounds for all these issues which we will talk about shortly. But in a nut shell blue light from digital devices and the fact that this blue light flickers is the major cause of digital eyestrain.
