Modern screen culture taught me how easily we can lose it.
Over the years, working with patients recovering from concussion and traumatic brain injury changed how I understand mental fatigue.
When the visual system is disrupted, the brain compensates.
And that compensation can feel like slower thinking, heavier focus, and reduced mental endurance.
What surprised me over time is that you don’t need a brain injury to experience subtle forms of visual overload.
Sustained screen demand quietly taxes the same systems, just at a lower intensity.
Many people describe it as burnout.
Sometimes, it’s visual fatigue.
Have you noticed your clarity fading at a certain point in the day?
