If your eyes feel dry, gritty or tired after spending time on a computer, phone or tablet, your screen habits may be contributing.
Dry eyes from screen time are common because people tend to blink less often when concentrating on digital devices. This allows the tear film covering the surface of the eye to evaporate more quickly, which can lead to irritation, fluctuating vision and discomfort.
Long periods of screen use are recognised as a factor that can worsen dry-eye symptoms, particularly when combined with air conditioning, heating, contact lenses or an existing tear-film problem.
At The Medical Eye Clinic in Exeter, dry-eye assessment focuses on understanding why symptoms are occurring so that treatment and practical changes can be tailored to the individual.
Can Screen Time Cause Dry Eyes?
Yes. Spending long periods looking at digital screens can contribute to dry-eye symptoms.
When we concentrate on a computer, phone or tablet, our blink rate often falls. We may also make more incomplete blinks.
Blinking is important because every complete blink spreads a fresh layer of tears across the surface of the eye. If you blink less often, tears have more time to evaporate between blinks.
This can make the tear film less stable and cause the eyes to become uncomfortable.
Screen use does not necessarily mean that something is permanently wrong with your eyes, but it can aggravate existing dry-eye problems or make mild symptoms much more noticeable.
Why Does Blinking Matter?
The surface of your eye is covered by a thin tear film that helps keep it lubricated and supports clear vision.
Each blink redistributes this tear film.
If you are blinking less frequently while looking at a screen, the tear film may begin to break up between blinks. This can lead to areas of dryness on the eye’s surface.<
You may notice that your vision becomes slightly blurry after staring at your screen for a while, then clears temporarily when you blink. This can happen when an unstable tear film affects the optical surface of the eye.
What Are the Symptoms of Dry Eyes From Screen Time?
Symptoms can vary, but commonly include:
- Dry or gritty eyes
- Burning or stinging
- Redness
- Tired or heavy-feeling eyes
- Intermittent blurred vision
- Sensitivity to light
- Watery eyes
- Difficulty wearing contact lenses
- A feeling that you need to blink frequently
Some people also describe their eyes as feeling strained or tired after prolonged screen use.
Dry eye can sometimes cause excessive watering because irritation triggers reflex tears. Although the eye is watering, these tears may not provide the stable lubrication needed to keep the surface comfortable.
Who Is Most Likely to Experience Dry Eyes From Screen Time?
Anyone can develop symptoms after long periods of screen use, but some people may be more susceptible.
This includes people who:
- Spend most of the working day on a computer
- Use several digital devices throughout the day
- Wear contact lenses
- Work in air-conditioned offices
- Already have dry-eye disease
- Have blepharitis or meibomian gland dysfunction
- Are over the age of 50
- Work in particularly dry environments
Multiple factors often occur together. For example, someone wearing contact lenses in an air-conditioned office while using a computer all day may experience more dryness than screen use alone would cause.
Does Working From Home Make Dry Eye Worse?
It can.
Working from home may mean spending long uninterrupted periods on a laptop, particularly if meetings, breaks and everyday conversations all take place through a screen.
Laptop screens may also be positioned lower or closer than traditional desktop monitors, which can encourage prolonged near focus.
The problem is not necessarily the device itself. The amount of uninterrupted screen time and your working environment are often more important.
How Can You Prevent Dry Eyes From Screen Time?
There are several practical steps that may help.
-
Take Regular Screen Breaks
Avoid looking continuously at a screen for long periods.
Regular breaks give your eyes a chance to blink normally and refocus at a different distance.
The NHS advises taking breaks to rest your eyes when using computers and other screens.
Even short breaks throughout the day can be more helpful than waiting until your eyes already feel uncomfortable.
-
Remember to Blink Fully
Because screen use can reduce blinking, making a conscious effort to blink completely can help refresh the tear film.
Every so often, close your eyes gently for a moment before reopening them.
This can be particularly helpful during activities that require intense concentration, such as:
- Reading documents
- Editing spreadsheets
- Video calls
- Gaming
- Design work
- Writing or coding
You do not need to count every blink. The aim is simply to avoid staring continuously without blinking properly.
- Position Your Screen Correctly
Your monitor position may influence how quickly tears evaporate.
The NHS recommends positioning a computer screen slightly below eye level.
Looking slightly downwards means the eyelids cover more of the eye’s surface than when you are looking upwards.
You should also try to position the screen at a comfortable distance and adjust the text size so that you are not leaning forward or straining to read.
- Reduce Direct Airflow
Fans, heaters and air conditioning can increase tear evaporation.
Try not to sit with:
- A desk fan blowing directly at your face
- Air conditioning aimed towards your eyes
- A heater positioned close to your workstation
If the room is particularly dry, a humidifier may help increase moisture in the air. NHS guidance also suggests avoiding prolonged exposure to dry, heated or air-conditioned environments where possible.
-
Adjust Your Workstation
Small changes to your desk setup can make screen use more comfortable.
Consider:
- Reducing glare from windows
- Adjusting screen brightness to suit the room
- Increasing text size
- Positioning the monitor directly in front of you
- Keeping your screen clean
- Taking regular breaks from close work
If you use multiple screens, try to arrange them so you are not constantly turning your head or straining your eyes.
-
Give Your Contact Lenses a Break
Contact lenses can contribute to dry-eye symptoms in some people.
If your eyes become increasingly uncomfortable during long screen sessions, switching to glasses for part of the day may help.
The NHS specifically advises people with dry eyes who wear contact lenses to consider taking them out and wearing glasses to rest their eyes.
If contact lenses are regularly becoming uncomfortable, speak to your optometrist or eye specialist.
-
Consider Lubricating Eye Drops
Artificial tears or lubricating drops can help relieve mild dry-eye symptoms.
There are many different formulations available, and the most appropriate option depends on your symptoms and how frequently you need treatment.
If you are using drops regularly, an eye-care professional may recommend a preservative-free formulation.
However, eye drops should not simply be used to mask persistent symptoms indefinitely. If you rely on them frequently without lasting relief, a dry-eye assessment may be worthwhile.
The Medical Eye Clinic’s existing dry-eye guidance also recommends identifying the underlying cause rather than treating all dry eye as a simple lack of moisture.
Is the 20-20-20 Rule Helpful?
You may have heard of the 20-20-20 rule, which suggests looking at something around 20 feet away for 20 seconds every 20 minutes.
It can be a useful reminder to interrupt prolonged screen use and refocus your eyes.
The exact numbers are less important than the principle: give your eyes regular breaks instead of maintaining uninterrupted near focus for hours at a time.
During those breaks, remember to blink normally as well.
Can Blue Light Glasses Prevent Dry Eyes?
Blue light itself is not the main reason screens contribute to dry eye.
The bigger issue is how screen concentration affects blinking and tear evaporation.
Blue-light filtering glasses may reduce certain types of glare for some people, but they do not replace good screen habits or treatment for genuine dry-eye disease.
If your main symptom is dryness, focus first on blinking, taking breaks, adjusting your environment and seeking professional advice if symptoms persist.
Can Screen Time Permanently Damage Your Eyes?
For most people, ordinary screen use does not permanently damage the eyes simply because you spend several hours looking at a monitor.
However, it can produce significant discomfort and can aggravate an existing dry-eye condition.
Persistent symptoms should not automatically be blamed on screens either.
Dry eye can also be associated with:
- Meibomian gland dysfunction
- Blepharitis
- Age-related tear changes
- Medication
- Contact lens use
- Certain medical conditions
If symptoms continue even after improving your screen habits, another underlying factor may be present.
When Should You See an Eye Specialist?
You should consider arranging an eye examination if:
- Dryness continues despite changing your screen habits
- Symptoms affect your work or daily activities
- Your vision frequently becomes blurred
- Your eyes remain persistently red or sore
- You struggle to wear contact lenses
- You rely on lubricating drops throughout the day
- Symptoms are becoming progressively worse
The NHS advises seeking professional assessment if dry eyes do not improve after trying self-care measures for several weeks.
A very painful red eye, sudden visual changes or marked light sensitivity require more urgent assessment.
How Are Persistent Dry Eyes Treated?
If screen habits are only part of the problem, treatment will depend on the underlying cause.
Options may include:
- Lubricating eye drops
- Preservative-free artificial tears
- Eyelid hygiene
- Warm compresses where appropriate
- Treatment for blepharitis
- Prescription anti-inflammatory treatment
- Punctal plugs in suitable patients
- Specialist management of meibomian gland dysfunction
The best approach depends on whether the problem is reduced tear production, excessive evaporation, inflammation or a combination of factors. The Medical Eye Clinic’s dry-eye content emphasises this personalised approach to treatment.
Dry Eye Assessment at The Medical Eye Clinic
If dry eyes from screen time are affecting your ability to work comfortably, it may be worth looking beyond your screen habits alone.
At The Medical Eye Clinic in Exeter, our specialists can assess the health of your eyes, eyelids and tear film to identify factors contributing to your symptoms.
From simple changes to your daily routine through to specialist dry-eye treatment, the aim is to develop an approach that addresses the cause rather than simply providing temporary relief.
Reduce the Impact of Screen Time on Your Eyes
For many people, dry eyes from screen time can be improved by making small, consistent changes.
Take regular breaks, blink fully, position your monitor comfortably and avoid unnecessary airflow around your eyes. If you wear contact lenses, giving your eyes occasional breaks can also help.
However, persistent dryness should not simply be accepted as part of working with computers.
If symptoms continue despite making these changes, contact The Medical Eye Clinic to arrange a dry-eye assessment and discuss the treatment options available.
Frequently Asked Questions
Can too much screen time cause dry eyes?
Yes. Screen use can contribute to dry eyes because people tend to blink less frequently while concentrating. This allows tears to evaporate more quickly.
How do I stop my eyes getting dry when using a computer?
Take regular breaks, blink fully, keep your screen slightly below eye level and avoid fans or air conditioning blowing directly towards your face. Lubricating eye drops may also help some people.
Why do my eyes get blurry after looking at a screen?
An unstable tear film can temporarily affect the smooth optical surface of the eye, causing fluctuating or blurred vision. If blurred vision is persistent rather than temporary, arrange an eye examination.
Do eye drops help with screen-related dry eyes?
Lubricating drops can relieve mild symptoms, but persistent dryness may have another underlying cause that needs assessment.
Should I wear glasses instead of contact lenses when using a computer?
If contact lenses become uncomfortable during prolonged screen use, wearing glasses for part of the day may help give the eyes a break.
When should I worry about dry eyes?
Seek professional advice if symptoms persist for several weeks, interfere with your vision or daily activities, or become progressively worse. Sudden sight changes, severe pain or marked redness need more urgent assessment.
