Why do digital devices cause eye strain?
Many factors can contribute to digital eye strain, some of them includes:
1. Extended period of looking at near objects.
Compare to looking at far objects, our eyes work harder when we are looking at near objects. Extended hours of looking at phones, laptop screens are like carrying "weights" for our eyes. Causing eye muscle to strain and tired out.
2. Reduce blinking
When we are engrossed into a task, whether it is a phone, screen or even watching a game on tv, we tend to blink less and this can dry up our eyes
3. Staying in a fixed position for too long
Staying in a fixed position, reduces blood circulation, and can cause stress on the neck and shoulder.
