Eyestrain has become one of the most frequent problems among screen users... and it is closely linked to posture.
When the screen is too low or too close, the head bends forward, the shoulders hunch, and the neck muscles tense. The result: neck pain, headaches, blurred vision, and eye strain.
Recent studies show that:
78.7% of young adults experience eye fatigue (dryness, stinging, blurriness) after prolonged screen use.
59.4% also report neck stiffness.
It's not just a "tired eyes" problem: posture and vision are directly linked.
Why does this happen?
Screen too low → head bent → strong neck tension
Less frequent blinking → dry eyes
Slumped posture → strained eye muscles → faster blurred vision
Prolonged immobility → general fatigue + headaches
This combination creates a vicious circle:
eye strain → poor posture → even more fatigue.
What you can do daily
Place the screen at eye level
Keep a distance of 50–70 cm
Take a micro-break every 30–40 minutes
Relax your shoulders and keep your head aligned
Blink voluntarily more often
Several scientific studies establish a clear link between poor posture (especially the head tilted forward) and symptoms of eye strain and uncomfortable vision after hours in front of a screen. These symptoms include visual fatigue, headaches, and blurred vision, often associated with neck and shoulder tension. Here are 2 links to consult:

Ocilys can help prevent the head from tilting forward, a common reflex when staring at a screen for too long.
