Digital eye strain describes eye and vision problems from prolonged use of digital devices like computers, tablets, e-readers and phones. It causes eye discomfort and vision issues. Factors contributing to digital eye strain include focusing on a single task for long periods, poor lighting, poor posture, not blinking enough, holding devices too close, and exposure to blue light from screens. Potential complications include problems with the retina, cataracts, age-related macular degeneration, and sleep disturbances. Treatment involves eye drops, artificial tears, blue light filtering glasses, anti-fatigue lenses, adjusting lighting, and wearing prescription glasses. Prevention focuses on taking regular breaks when using devices and following ergonomic guidelines.

commonly emitted from digital devices
• viewing a screen that doesn’t have properly adjusted lighting

8. Complications of digital eye strain
 Problems with your retina
 Cataract
 Age-related macular degeneration
 Sleep disturbances

9. Diagnosis

• The physician may also do a physical exam to look for muscle imbalance,
uncorrected refractive errors (nearsightedness or farsightedness) and other

10. Treatment
Use lubricating eye drops.
Use artificial tears
Use of blue light filtering glasses
Use of anti fatigue lenses
Adjust lighting based on activity.
Wearing glasses

1. Managing the myopia epidemic and digital eye strain post COVID-19
pandemic – What eye care practitioners need to know and implement?
Jameel Rizwana Hussaindeen, Aparna Gopalakrishnan, et.al has been found that
possible complications of online classes for children in coronavirus pandemic are:
Dry eye disease

Digital Eye strain

25. Other researches done on Digital eye strain
2. Researches compare it with cannabis addiction, “Too much
exposure to screens of mobiles and laptops leads a feeling of
isolation and anxiety in the current scenario. It can lead to
depression and an increase in neurotic traits such as nail
biting, thumb sucking and hair pulling.”
