Seek care promptly for sudden vision changes, eye pain, injury, flashes or new floaters, or symptoms that persist or worsen. This guide is educational and is not a diagnosis.

What people mean by digital eye strain

Digital eye strain is an umbrella description for discomfort associated with prolonged screen use. People may report tired or dry-feeling eyes, blurred vision, headaches, or neck and shoulder discomfort. Those experiences can have multiple causes, so a symptom list cannot identify a diagnosis.

What can change during screen work

Concentrated near work may reduce or change blinking, hold the eyes at one viewing distance, and keep posture relatively fixed. Screen brightness, reflections, text size, task duration, contact-lens use, and uncorrected vision can all change the experience.

A practical hierarchy

  1. Make text and contrast comfortable before adding an exercise.
  2. Interrupt long blocks with regular breaks.
  3. Use real distant targets when a cue calls for distance viewing.
  4. Keep blinking and gaze movement gentle.
  5. Change the reminder interval when it becomes distracting.
  6. Seek professional care when symptoms are concerning or persistent.

What Exereye measures

Exereye can count completed routines and show activity trends. These are habit signals. They are not measurements of eye health, focus ability, tear quality, or visual function.
