Smartphone and iPad screens are only a few inches wide.
However, they are packed with infinite information and stimulation.
Humans fixate their gaze as if being sucked into them; while we think we are "looking," we are actually "not moving our eyes."
Then, a chain reaction begins:
Fixed gaze
↓
Contraction of suboccipital muscles
↓
C1/C2 locking
↓
Contraction of scalene muscles
↓
Decreased thoracic mobility
↓
Shallow breathing
This is not just "eye strain."
It is a structural problem for modern people that connects the cervical spine, breathing, brain, and even sensitivity.
