Quick answer
What is Eye strain?
Eye strain (sometimes called digital eye strain or computer vision syndrome) is a common, temporary and harmless condition caused by using the eyes intensively for prolonged periods — most often looking at screens, but also reading, driving long distances, or doing close work in poor light. Symptoms can include tired, aching or sore eyes, a feeling of dryness or grittiness, blurred vision (usually temporary), headaches, and difficulty focusing after prolonged use, and there may be neck and shoulder discomfort from posture.
- How it is treated: Eye strain is eased by simple habits that give the eyes regular rest and reduce dryness.
- Self-care: Take regular breaks (the "20-20-20" rule), blink regularly and use lubricating drops for dryness, position and adjust the screen well, reduce glare, ensure good lighting and posture, and keep any glasses prescription up to date.
- When to seek help: Eye strain usually needs no medical attention.
What it is
Eye strain (sometimes called digital eye strain or computer vision syndrome) is a common, temporary and harmless condition caused by using the eyes intensively for prolonged periods — most often looking at screens, but also reading, driving long distances, or doing close work in poor light. Symptoms can include tired, aching or sore eyes, a feeling of dryness or grittiness, blurred vision (usually temporary), headaches, and difficulty focusing after prolonged use, and there may be neck and shoulder discomfort from posture. When using screens, people tend to blink less, which contributes to dryness, and hold a fixed focus for long periods, which tires the focusing muscles. Eye strain does not damage the eyes and does not cause long-term harm, but it is uncomfortable and can affect concentration and comfort. Symptoms that persist even with breaks, or come with other visual problems, may indicate an uncorrected vision problem worth checking with an eye test.
How it is treated
Eye strain is eased by simple habits that give the eyes regular rest and reduce dryness. A widely recommended measure is the "20-20-20" rule: every 20 minutes, look at something about 20 feet (6 metres) away for at least 20 seconds, to relax the focusing muscles. Other helpful steps include blinking regularly (and consciously more when on screens) and using lubricating drops if the eyes feel dry, adjusting screen position (about arm's length, top of screen at or just below eye level) and brightness to comfortable levels, reducing glare, ensuring good lighting, taking regular breaks, and maintaining good posture. Making sure any glasses prescription is up to date is important, as an uncorrected or outdated prescription is a common contributor. Because eye strain is harmless, reassurance is part of care. If symptoms persist despite these measures, or there are other visual symptoms, an eye test is advisable to check for an underlying vision problem. The reassuring message is that eye strain is harmless and usually settles with regular breaks and good habits.
