Causes
Main causes
- Staring at a screen for hours without a break
- Poor lighting – either too bright or too dim
- Glare or reflections on the screen
- Uncorrected vision problems, like needing glasses
- Sitting too close or too far from the screen
- Not blinking as often while looking at a screen
Risk factors
- Already having dry eyes or other eye conditions
- Using screens for more than 2 hours a day
- Working in a very dry or air-conditioned room
- Being over age 40, when the eye’s lens becomes less flexible
- Taking certain medicines that dry the eyes (like antihistamines or decongestants)
When to see a doctor
See a doctor urgently if:
- If you have sudden vision loss or double vision
- If you have severe eye pain
Book a routine appointment if:
- If your eye strain symptoms do not improve with rest and simple changes
- If you get frequent headaches that you think are related to your eyes
- If you think you may need new glasses or contact lenses
Diagnosis
A healthcare provider, such as an optometrist or ophthalmologist, will ask about your screen habits and symptoms. They will also do a basic eye exam to check your vision and eye health.
Tests that may be done
- Visual acuity test – reading letters on a chart from a distance
- Refraction test – to see if you need glasses
- Eye muscle test – to see how well your eyes work together
- Tear film evaluation – to check for dry eyes
What to expect at your appointment
The exam is quick and painless. You may be asked to look at a light, read letters, or follow an object with your eyes. The doctor will let you know if any problems are found and what you can do next.
Treatment
Treatment for eye strain usually involves simple self-care steps. The goal is to reduce symptoms and prevent them from coming back. If an underlying condition like dry eye or a need for glasses is found, your doctor can help.
Self-care at home
- Follow the 20-20-20 rule: Every 20 minutes, look at something about 20 feet (6 meters) away for at least 20 seconds.
- Adjust your screen brightness to match the light in the room.
- Reduce glare by using an anti-glare screen filter or by moving your screen away from windows.
- Blink often to keep your eyes moist.
- Use artificial tears (over-the-counter eye drops) if your eyes feel dry – ask your pharmacist for advice.
- Position your screen so it is about an arm’s length away and slightly below eye level.
- Take longer breaks every hour – stand up, stretch, and look into the distance.
Medical treatments
If your eye strain is linked to an uncorrected vision problem, your doctor may prescribe glasses or contact lenses for screen use. For dry eyes, they may recommend certain types of eye drops. No specific medications are typically needed for eye strain alone.
When is surgery considered?
Not applicable. Surgery is not used to treat or prevent eye strain.
Living with this condition
Living with eye strain means building good screen habits into your daily routine. Take short breaks often, set up your work area for comfort, and remember to blink. Most people find that symptoms improve quickly once they start these habits.
Lifestyle tips
- Limit recreational screen time when possible, especially before bed.
- Spend time outdoors each day – natural light and distance vision help relax your eyes.
- Consider using a blue light filter on your device at night, but know that the evidence is mixed on how much it helps.
Diet and exercise
A balanced diet rich in omega-3 fatty acids (found in fish, flaxseed, and walnuts) may help with dry eyes. Drinking plenty of water keeps your whole body hydrated. Regular exercise improves circulation and can reduce tension that contributes to eye strain.
Mental health and emotional wellbeing
Eye strain can be frustrating and tiring. It may make you feel less productive or more irritable. Taking breaks not only helps your eyes but also reduces mental fatigue. If eye strain affects your mood, talk to your doctor or a trusted friend.
Prevention
Yes, in most cases eye strain can be prevented by practicing good screen habits. Setting up your work area properly, taking regular breaks, and having regular eye exams are the best ways to avoid it.
Screening programmes
Regular eye exams – every one to two years for adults – can catch vision problems early and help you avoid eye strain. If you use screens a lot, tell your eye doctor so they can check for signs of strain.
Complications
If left untreated
- Persistent headaches
- Ongoing eye discomfort that makes it hard to focus
- Neck and shoulder pain from poor posture
Long-term outlook
The outlook is excellent. Eye strain does not cause permanent damage to your eyes. Most people feel better quickly after making small changes to their screen habits and environment.
