Digital Eye Strain: When Screen Time Means You Might Need an Eye Test
Remote working, video calls and constant screen use have become a normal part of daily life for many people. Whether you’re working from home, commuting with a laptop, or spending evenings on your phone or tablet, the amount of time we spend looking at screens has increased dramatically.
While digital devices are essential for work and communication, too much screen time can lead to digital eye strain — a common condition that can affect comfort, productivity and even your vision.
In this article, we explain what digital eye strain is, the symptoms to watch for, and when it might be time to book an eye test.
What Is Digital Eye Strain?
Digital eye strain (sometimes called computer vision syndrome) refers to a group of eye and vision problems caused by prolonged use of digital screens.
When you look at screens for long periods, your eyes work harder than usual. You may blink less often, focus at a fixed distance for extended periods, and strain your eye muscles as they constantly adjust to digital text and images.
Over time, this can lead to discomfort and vision problems.
Why Remote Working Has Increased Eye Strain
Many people now spend 6–10 hours per day on screens, especially those working remotely or in hybrid roles.
Common causes of eye strain while working from home include:
- Extended computer use without breaks
- Poor workstation lighting
- Screens positioned too close or too far away
- Smaller laptop screens compared with office monitors
- Increased use of phones and tablets outside working hours
Without the natural breaks we used to get during office life—walking between meetings, commuting or talking to colleagues—our eyes often remain fixed on screens for much longer periods.
Symptoms of Digital Eye Strain
If you regularly work on a computer or digital device, you may notice some of the following symptoms:
- Tired or aching eyes
- Blurred vision
- Headaches after screen use
- Dry or irritated eyes
- Difficulty focusing
- Sensitivity to light
- Neck and shoulder pain
These symptoms often become worse towards the end of the workday, especially after long periods of screen use.
If these problems occur frequently, it may indicate that your eyes are struggling to cope with your current visual demands.
How Screen Time Affects Your Vision
While digital devices themselves do not permanently damage your eyes, they can highlight underlying vision problems.
For example, screen use may reveal:
- An outdated glasses prescription
- Difficulty focusing at intermediate distances
- Early signs of long-sightedness
- Dry eye syndrome
Because computer screens sit at a unique distance between reading and distance vision, they often expose issues that may not be obvious in everyday activities.
When Should You Book an Eye Test?
If you regularly experience eye strain when working on screens, it may be time to consider an eye examination.
You should consider booking an eye test if you:
- Frequently experience headaches when using screens
- Notice blurred or fluctuating vision
- Struggle to focus after long periods of computer work
- Feel your eyes are constantly tired
- Have not had an eye test in the last two years
An eye test can determine whether your prescription has changed or whether specialist lenses designed for screen use could improve your comfort.
Regular eye examinations are also important for detecting early signs of eye health issues.
Tips to Reduce Digital Eye Strain
There are several simple ways to reduce strain while working on screens.
Follow the 20-20-20 rule
Every 20 minutes, look at something 20 feet away for 20 seconds to allow your eyes to relax.
Adjust your screen position
Your screen should sit roughly an arm’s length away and slightly below eye level.
Improve lighting
Avoid glare from windows or overhead lights by adjusting your screen or workspace.
Remember to blink
People blink less frequently when using screens, which can cause dry eyes. Try to blink consciously and take short breaks.
Consider specialist lenses
For some people, lenses designed for computer use can reduce eye strain and improve focus.
Book an Eye Test If Screen Use Is Affecting Your Eyes
With modern lifestyles involving more digital devices than ever, digital eye strain has become increasingly common. Fortunately, an eye examination can identify whether your symptoms are related to your vision and help you find the best solution.
