At a glance
- Long or visually demanding screen sessions can contribute to temporary eye strain, dryness, headaches and intermittent blur.
- Ordinary screen use has not been shown to damage the retina, and blue-light filtering spectacles are not a proven treatment for digital eye strain.
- Comfortable viewing distance, readable text, reduced glare, regular breaks, blinking and time outdoors can make screen use easier.
What is digital eye strain?
Digital eye strain describes symptoms that can occur during or after sustained use of computers, tablets, phones and other near displays. Symptoms may include tired or sore eyes, dryness, burning, headaches, neck or shoulder discomfort and blur that comes and goes.
These symptoms are real, but they are not the same as permanent eye damage. Several factors can contribute at once, including reduced blinking, glare, small text, an unsuitable viewing distance, dry air, uncorrected prescription and prolonged concentration. A peer-reviewed review of digital eye strain discusses this combination of ocular and visual factors.
Does screen blue light damage the eyes?
There is no good evidence that the light from ordinary computer and phone screens causes retinal damage during normal use. Screen brightness, glare and prolonged visual demand can still affect comfort, and late-night use can interfere with sleep routines.
Blue-light filtering lenses should not be presented as a proven way to prevent retinal damage or treat digital eye strain. A Cochrane review found that blue-light filtering spectacles probably make no difference to computer-related eye strain in the short term.
How can screen-related discomfort be reduced?
- Use a comfortable distance: keep the screen far enough away that text is easy to read without leaning forward, and enlarge text instead of moving very close.
- Reduce glare: adjust screen angle, room lighting and window reflections. Match display brightness to the surrounding room rather than using an unnecessarily bright screen.
- Take regular visual breaks: look into the distance, change posture and move around. The exact timing can be adapted to the task; a break habit matters more than treating one interval as a medical rule.
- Blink fully: concentrated screen use can reduce blinking. Conscious blinking and appropriate dry-eye advice may help when dryness is part of the problem.
- Check the prescription: even a small uncorrected refractive error can increase visual effort for some people.
Screen time, children and myopia
Screen time should be considered alongside outdoor time, sleep, physical activity and the total amount of sustained near work. Myopia has several risk factors; one device or one habit does not explain every child’s prescription.
The Australian Government’s guidance for children under five places sedentary screen time within a full day of movement, active play and sleep. For school-aged children, families can plan device use around school requirements, regular breaks, outdoor activity and a consistent sleep routine.
Read SVO’s evidence-based discussion of outdoor time, near work and childhood myopia for the limits of observational screen and lockdown research.
When should you arrange an eye examination?
Arrange an assessment if symptoms are frequent, worsening or continue after sensible screen changes, or if there is persistent blur, double vision, eye pain or a noticeable change in vision. Sudden vision loss, severe pain, new flashes, a sudden increase in floaters or a curtain-like shadow needs urgent assessment.
Review SVO’s advanced eye health testing or arrange an appointment. The optometrist can check eye health, prescription and visual function and recommend care based on the findings.
Screen-time and eye-strain questions
What are common symptoms of digital eye strain?
Common symptoms include tired or sore eyes, dryness, burning, headaches, neck or shoulder discomfort and intermittent blur during or after sustained screen use.
Can ordinary screen use permanently damage the eyes?
Normal use of phones and computer screens has not been shown to damage the retina. Screens can still contribute to temporary discomfort, reduced blinking and disrupted sleep habits.
What is the simplest way to reduce screen-related eye discomfort?
Use readable text at a comfortable distance, reduce glare, blink fully and take regular breaks to look farther away and move. Persistent symptoms should be assessed rather than self-diagnosed.
