Quick Answer
Eyestrain is a common condition in which the eyes become tired from intense use, such as prolonged screen time, reading or long-distance driving; it is annoying but usually not serious. [1] Symptoms include sore, burning or dry eyes, blurred vision and headache. [1] Treatment involves the 20-20-20 rule, better lighting and artificial tears; see an eye specialist if self-care fails. [2]
What the research says
Eyestrain symptoms are extremely common among screen users. In a meta-analysis of 63 studies, the pooled prevalence of asthenopia (eyestrain) symptoms was 51%, rising to 90% among digital device users and 77% among computer workers (Song et al., J Glob Health, 2026). [5]
More screen time means more risk, especially past about 2.5 hours a day. In a meta-analysis covering 71,633 university students, screen time was associated with digital eye strain (odds ratio 1.96), and the risk rose sharply after about 2.5 hours of daily screen time, by more than 15% for each additional hour (Zeng et al., BMC Public Health, 2026). [6]
Regular breaks are linked with less eyestrain, but the exact 20-20-20 timing is not proven. The Song meta-analysis found regular breaks were associated with lower odds of asthenopia (odds ratio 0.21), yet in a trial of 30 young adults doing a 40-minute reading task, 20-second breaks every 5, 10, or 20 minutes did not significantly change reported symptoms (P = .70) (Johnson & Rosenfield, Optom Vis Sci, 2023). [5] [7]

What Is Eyestrain?
Eyestrain is a common condition that occurs when your eyes get tired from intense use, such as while driving long distances or staring at computer screens and other digital devices. [1]
Eyestrain can be annoying. But it usually isn't serious, and it goes away once you rest your eyes or take other steps to reduce your eye discomfort. In some cases, symptoms of eyestrain can indicate an underlying eye condition that needs treatment. [1]
Extended use of computers and other digital devices is one of the most common causes. This pattern is called computer vision syndrome, also known as digital eyestrain [1] [3]. People who look at screens two or more hours in a row every day have the greatest risk of this condition. [1] [3]
Symptoms
Eyestrain symptoms include:
When to See a Doctor
See an eye specialist if self-care steps don't relieve your eyestrain. [1] Because eyestrain symptoms can sometimes signal an underlying eye problem, such as uncorrected vision or dry eyes, a professional exam can rule out causes that simple rest will not fix.
Causes
Common causes of eyestrain include:
Looking at digital device screens [1]
Reading without pausing to rest your eyes [1]
Driving long distances and doing other activities involving focusing for a long time [1]
Being exposed to bright light or glare [1]
Straining to see in very dim light [1]
Having an underlying eye problem, such as dry eyes or uncorrected vision, called refractive error [1]
Being stressed or fatigued [1]
Being exposed to dry moving air from a fan, a heating system or an air-conditioning system [1]
Why Screens Strain Eyes More Than Print
Computer use strains eyes more than reading print material because people tend to blink less while using computers, and blinking is key to moistening the eyes. [1] Users also view digital screens at less than ideal distances or angles, use devices that have glare or reflection, and use devices with poor contrast between the text and the background. [1] [3]
In some cases, an underlying eye problem, such as eye muscle imbalance or uncorrected vision, can cause or worsen computer vision syndrome. [1]
Other factors that can make the condition worse include glare on the screen, poor posture, the setup of a computer workstation, and circulating air, such as from air conditioning or a nearby fan. [1]
Risk Factors
The single biggest risk factor is the amount of uninterrupted screen time. People who look at screens two or more hours in a row every day have the greatest risk of digital eyestrain. [1] [3] Additional risks include working in poorly lit or glare-heavy environments, sitting in dry circulating air, poor posture at the workstation, and having uncorrected vision problems that go undiagnosed.
Complications
Eyestrain doesn't have serious or long-term consequences, but it can be aggravating and unpleasant. It can make you tired and reduce your ability to concentrate. [1]
Diagnosis
Your eye specialist will ask you questions about factors that might be causing your symptoms. You may have an eye exam during your visit, including a vision test. [2] This helps distinguish simple eyestrain from underlying eye conditions that need specific treatment.
Treatment
Generally, treatment for eyestrain consists of making changes in your daily habits or environment. Some people may need treatment for an underlying eye condition. [2]
For some people, wearing glasses that are prescribed for specific activities, such as for computer use or for reading, helps reduce eyestrain. Your eye specialist may suggest that you take regular eye breaks to help your eyes focus at different distances. [2]
Lifestyle and Home Remedies
Consider these tips to reduce or prevent eyestrain.
Adjust the lighting. When watching television, it may be easier on your eyes if you keep the room softly lit. When reading printed materials or doing close work, try to position the light source behind you and direct the light onto your page or task. If you're reading at a desk, use a shaded light positioned in front of you. The shade will keep light from shining directly into your eyes. [2]
Take breaks. When reading or doing close work, take occasional breaks and rest your eyes by looking away from the page, digital screen or task. [2]
Limit screen time. This is especially important for children, who may not make the connection between extended viewing, eyestrain and the need to rest their eyes regularly. [2]
Use artificial tears. Nonprescription artificial tears can help prevent and relieve dry eyes. Use them even when your eyes feel fine to keep them well lubricated and prevent a recurrence of symptoms. Your eye specialist can suggest which eye drops might be best for you. Avoid eye drops with a redness remover, as these may worsen dry eye symptoms. Eye drops without preservatives can be used as often as needed. If you use drops containing preservatives more than four times a day, you may develop sensitivity to the preservative, so switching to preservative-free drops can help. [2]
Improve the air quality of your space. Changes that may help prevent dry eyes include using a humidifier, adjusting the thermostat to reduce blowing air and avoiding smoke. If you smoke, consider quitting. Moving your chair to a different area may reduce the amount of dry moving air on your eyes and face. [2]
Choose the right eyewear for you. If you need glasses or contacts and work at a computer, consider investing in glasses or contact lenses designed specifically for computer work. Ask your optometrist about lens coatings and tints that might help too. [2]
Tips for Computer Work
Computer use is a common cause of eyestrain. If you work at a desk and use a computer, these self-care steps can help take some of the strain off your eyes.
Blink often to refresh your eyes. Many people blink less than usual when working at a computer, which can contribute to dry eyes. Blinking produces tears that moisten and refresh your eyes. Try to make it a habit to blink more often when looking at a monitor. [2]
Take eye breaks. Throughout the day, give your eyes a break by looking away from your monitor. Try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. [2]
Check the lighting and reduce glare. Bright lighting and too much glare can strain your eyes and make it difficult to see objects on your monitor. The worst problems are generally from sources above or behind you, including fluorescent lighting and sunlight. Consider turning off some or all of the overhead lights. If you need light for writing or reading, use an adjustable desk lamp. Close blinds or shades, and avoid placing your monitor directly in front of a window or white wall. Place an anti-glare cover over the screen. [2]
Adjust your monitor. Position your monitor directly in front of you about an arm's length away so that the top of the screen is at or just below eye level. It also helps to have a chair you can adjust. [2]
Use a document holder. If you need to refer to print material while you work on your computer, place it on a document holder. Some holders sit between the keyboard and the monitor; others sit to the side. The goal is to reduce how much your eyes need to readjust and how often you turn your neck and head. [2]
Adjust your screen settings. Enlarge the type for easier reading. Adjust the contrast and brightness to a level that's comfortable for you. [2]
Alternative Medicine
Some eyestrain symptoms may be relieved by natural products, such as the omega-3 fatty acids in fish oil, but further study is needed. [2] Talk with your eye specialist if you're considering supplements to help relieve your symptoms.
Preparing for Your Appointment
If you have eye discomfort, headache or vision changes that don't improve with self-care, make an appointment with an eye specialist. [2]
What you can do: list any symptoms you've been having and for how long; list your key medical information, including other medical conditions and any medications, vitamins and supplements you're taking; keep a daily log of the time you spend on activities that strain your eyes, such as looking at digital devices, reading and being exposed to glare; and list questions to ask during your appointment.
Useful questions include: What is likely causing my symptoms? What are other possible causes? Do I need any tests to confirm the diagnosis? What treatment approach do you recommend? What changes could I make to my work or home environment, including my computer desk, to help reduce symptoms? What other self-care measures might help me? Do I need to return for a follow-up appointment?
What to expect from your doctor: your eye specialist may ask about your symptoms, when they started, whether they have changed or worsened, how severe the discomfort is, whether you use a computer and how it is set up, whether air conditioning or a fan blows air around your face, how much time you spend on digital devices each day, what triggers or relieves symptoms, and when your last vision exam was.
Conclusion
Eyestrain is one of the most relatable modern discomforts: tired, burning eyes, blurring vision, headaches, and a sore neck after a long stretch at a screen, a book, or the wheel. The reassuring part is equally clear: eyestrain is common, rarely serious, and highly fixable. It almost always eases with rest and a handful of habit changes.
The most widely recommended tool is the 20-20-20 rule (every 20 minutes, look at something 20 feet away for at least 20 seconds), paired with small environmental fixes: soft room lighting, a monitor set an arm's length away at eye level, an anti-glare setup, artificial tears for dryness, and a humidifier to fight dry circulating air. If symptoms persist despite self-care, an eye specialist can run a simple exam to check for an underlying issue such as uncorrected vision or dry eye disease, and may prescribe glasses tailored to your activities.
Take the Next Step
Start with the 20-20-20 rule today and adjust your workstation lighting this week. If eyestrain persists beyond two to three weeks of self-care, book a visit with an eye specialist. It takes one simple exam to know what's really going on.
FAQ: Eyestrain
What is eyestrain?
Eyestrain is a common condition that occurs when your eyes get tired from intense use, such as while driving long distances or staring at computer screens and other digital devices. [1] It usually isn't serious and goes away with rest. [1]
What are the symptoms of eyestrain?
Symptoms include sore, tired, burning or itching eyes; watery or dry eyes; blurred or double vision; headache; sore neck, shoulders or back; increased sensitivity to light; difficulty concentrating; and feeling that you cannot keep your eyes open. [1]
Can eyestrain cause permanent damage?
No. Eyestrain doesn't have serious or long-term consequences, though it can be aggravating, make you tired, and reduce your ability to concentrate. [1]
What is the 20-20-20 rule for eye strain?
Every 20 minutes, look at something 20 feet away for at least 20 seconds. [2] This gives your eyes a break from close-up focus and helps them refocus at different distances.
Should I see a doctor for eyestrain?
See an eye specialist if self-care steps don't relieve your eyestrain, or if you have eye discomfort, headache or vision changes that don't improve. [1] [2] An exam can check for underlying eye conditions such as uncorrected vision or dry eye disease.
What causes eyestrain?
Common causes include long screen sessions, reading or driving without breaks, glare or dim light, dry moving air and uncorrected vision problems. Stress and tiredness can make it worse.
Do blue light glasses help with eye strain?
Current evidence does not show that blue light filtering glasses reduce digital eye strain. Taking regular breaks, blinking more, and fixing lighting and screen position help more.
Can eyestrain cause headaches?
Yes. Headache is a common eyestrain symptom, often along with a sore neck or shoulders. A sudden, severe headache, or one with vision loss, weakness or confusion, is not typical eyestrain and needs emergency care.
Do eye drops help eyestrain?
Nonprescription artificial tears can ease dryness. Avoid drops with a redness remover, which may worsen dry eyes, and choose preservative-free drops if you use them more than four times a day.
How far should my computer screen be from my eyes?
Place the monitor about an arm's length away, directly in front of you, with the top of the screen at or just below eye level. Enlarging text and reducing glare also help.
