Computer Eye Strain
Computer eye strain – also known as digital eye strain, or part of a larger problem called computer vision syndrome – is when symptoms of eye strain and dry eyes are directly linked to the use of digital screens. Focusing up close for long periods of time without looking into the distance definitely takes its toll on the eyes, making them dry, short sighted, and potentially damaged permanently from the increased blue light levels.
People are increasingly becoming aware of the potentially harmful effects of blue light. Blue light is emitted from many sources, including digital screens (such as your phone, tablet, computer, laptop and TV) and fluorescent and energy efficient lights. Another source of blue light is the sun – human circadian rhythms have evolved to use this light source to regulate sleep/wake patterns and to feel more alert during the day.
Unfortunately, this also means that the increased use of digital devices in the home and office at night time leads to a disruption of the natural sleep cycle, causing increased fatigue.
Increased exposure to blue light not only causes feelings of dry and tired eyes, but it can also damage the precious sight-giving cells at the back of the eye, leading to permanent vision loss.
