Long days on a laptop or phone leave many of us with tired, dry eyes and a dull headache by the evening. That is digital eye strain — sometimes called computer vision syndrome — and it is one of the most common eye complaints today. The good news: small changes to how you work and rest your eyes make a real difference.
What digital eye strain feels like
- Tired, sore or heavy-feeling eyes
- Dryness, grittiness or watering
- Headaches, often around the eyes and forehead
- Blurred vision, especially after long screen sessions
- Neck and shoulder stiffness from poor posture
Symptoms usually ease after you rest your eyes, but they return quickly if nothing about your screen habits changes.
Why screens tire your eyes
Three things combine. First, we blink less when we concentrate on a screen, so the surface of the eye dries out. Second, your focusing muscles work continuously at one fixed, close distance. Third, glare and poor lighting force your eyes to work harder. Uncorrected vision makes all of it worse, which is why an up-to-date prescription matters.
Try the 20-20-20 rule
Every 20 minutes, look at something about 20 feet (6 metres) away for 20 seconds. It sounds simple, and it is — but it gives your focusing muscles the regular break screens deny them. Set a quiet reminder until it becomes a habit, and take proper breaks away from your desk through the day. Standing up and stretching at the same time helps your neck and shoulders too.
Set your screen up right
- Distance: keep the screen about an arm’s length away.
- Height: the top of the screen should be at or just below eye level.
- Brightness: match your screen brightness to the room around you, and avoid working in a dark room with a bright screen.
- Glare: angle your screen away from windows and bright lights, or use a matte screen filter.
- Text size: enlarge text rather than leaning in closer to read it.
Blink, and keep your eyes moist
Make a point of blinking fully and often while you work — most of us blink partly or not at all when we concentrate. If your eyes often feel dry, mention it to an optometrist at your next eye exam. Do not rub sore eyes, and keep air from fans and air conditioning from blowing directly onto your face.
Do blue light glasses help?
Blue light filtering lenses and anti-reflective coatings may help some people feel more comfortable during long screen days, but the evidence is still developing. They work best as part of better screen habits — breaks, good lighting and an up-to-date prescription — not as a replacement for them.

Children and screens
Children spend long hours on screens for school and play, and they are less likely to mention tired eyes. Encourage the same 20-20-20 habit, keep recreational screen time reasonable, and make sure they get time outdoors every day. If a child squints, holds screens very close, or complains of headaches, book an eye exam.
When to see an optometrist
Book an eye exam if your symptoms keep coming back, if your vision is blurred or doubled, or if you have eye pain or headaches that do not go away. Most eye strain improves with the habits above, but persistent symptoms deserve a proper check. At FrameAura, our eyeglasses can be ordered with a blue light filter and anti-reflective coating — choose the lens features when you order, and upload your prescription so we can check it before your lenses are made.
