If you are reading this, you might already be familiar with the sensation. It feels like sand has been rubbed into your eyelids. Your vision might be slightly blurred, and a dull ache may be pulsing behind your forehead.
In our modern, hyper-connected world, staring at screens is practically unavoidable. From the moment we wake up to check our phones to the hours spent working on laptops, our eyes are under constant siege.
However, digital eye strain—often called Computer Vision Syndrome—does not have to be the price of productivity. While we cannot always escape our devices, we can certainly change how we interact with them.
Learning how to soothe sore eyes is essential for maintaining long-term vision health. It involves a combination of immediate relief techniques and preventative lifestyle adjustments.
This guide will walk you through evidence-based methods to alleviate discomfort and protect your vision, all grounded in the latest research. You do not have to suffer in silence or squint through the pain any longer.
What Is Computer Vision Syndrome?
Before we dive into the remedies, it is helpful to understand exactly what is happening to your eyes.
Computer Vision Syndrome (CVS) describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and mobile phone use.
Unlike reading a printed page, reading from a screen requires your eyes to work harder. The letters on a computer screen are often not as precise or sharply defined, the level of contrast is variable, and the presence of glare and reflections can make viewing difficult.
Common Symptoms
If you have been working at a screen for hours, you might recognise these classic signs:
- Eyestrain and fatigue: A feeling of heaviness or tiredness in the eyes.
- Dryness and irritation: A gritty, burning, or stinging sensation.
- Blurred vision: Difficulty focusing on distant objects after looking at the screen.
- Headaches: Often originating behind the eyes or at the temples.
- Neck and shoulder pain: Caused by leaning forward to see the screen better.
According to the American Optometric Association, the extent to which individuals experience these symptoms depends largely on the level of their visual abilities and the amount of time spent looking at a digital screen.
Actionable Steps to Soothe Sore Eyes
Relief requires a two-pronged approach: immediate soothing techniques to stop the pain now, and ergonomic adjustments to prevent it from returning. Here are the most effective strategies.
1. Master the 20-20-20 Rule
This is the gold standard for preventing digital eye strain. The rule is simple, effective, and easy to remember.
- Every 20 minutes, take a break from your screen.
- Look at something 20 feet (6 metres) away.
- Do this for at least 20 seconds.
Why does this work? Looking at screens requires your ciliary muscles (the muscles inside the eye) to contract to maintain focus. Looking into the distance allows these muscles to fully relax, breaking the cycle of fatigue.
2. Strategic Blinking and Artificial Tears
One of the primary causes of screen-induced soreness is dryness. Research suggests that when we stare at screens, our blink rate drops significantly—often by as much as 66%. Furthermore, the blinks we do perform are often incomplete, meaning the eyelid does not fully cover the cornea.
To combat this:
- Blink consciously: Make an effort to blink fully and slowly every few minutes. Imagine you are slowly pressing your eyelids together.
- Use lubricating eye drops: Preservative-free artificial tears can replenish moisture. Avoid drops that promise to “remove redness,” as these often contain vasoconstrictors that can worsen irritation over time.
For persistent dryness, consult the NHS guide on dry eyes to determine if you need a specific type of viscosity in your eye drops.
3. Optimise Your Lighting
Your environment plays a massive role in how hard your eyes have to work. Excessive bright light, either from harsh interior lighting or sunlight coming through a window, leads to glare.
- Reduce glare: If possible, position your computer screen so that windows are to the side, rather than in front or behind it.
- Adjust ambient light: The brightness of your room should roughly match the brightness of your screen. If your screen looks like a light source in a dark room, it is too bright. If it looks dull and grey, it is too dark.
- Use matte filters: If you cannot control the lighting in your office, consider an anti-glare screen filter.
4. Perfect Your Workstation Ergonomics
Improper posture forces your eyes to strain. The Health and Safety Executive (HSE) in the UK provides strict guidelines for Display Screen Equipment (DSE) to minimise injury.
Follow these ergonomic principles:
- Screen distance: The monitor should be an arm’s length away (approximately 50 to 70 cm) from your face.
- Screen height: The top of the screen should be at or slightly below eye level. This ensures you are looking slightly downwards, which allows your eyelids to cover more of your eyes, reducing evaporation and dryness.
- Font size: Increase the text size so you do not have to lean forward to read.
5. Adjust Display Settings
Your computer has built-in tools to help you.
- Colour temperature: Blue light has a short wavelength and is known to cause more scatter, which reduces contrast and increases strain. Reduce the colour temperature of your display to lower the amount of blue light emitted. This usually makes the screen appear slightly more orange or reddish.
- Refresh rate: If you are using an older monitor, a low refresh rate can cause an imperceptible flicker that tires the eyes. Ensure your settings are optimised for the highest refresh rate possible (usually 60Hz or higher).
6. Practice Eye Yoga
While it sounds trendy, simple eye exercises can physically relieve tension in the extraocular muscles.
- Palming: Rub your hands together vigorously until they are warm. Place your cupped palms over your closed eyes without applying pressure. Breathe deeply and relax in the darkness for 30 seconds.
- Figure Eights: Imagine a giant figure eight on the wall about 3 metres in front of you. Trace the shape with your eyes slowly for 30 seconds, then switch directions.

7. Warm Compresses
If you finish the day with gritty, sore eyes, a warm compress is arguably the most soothing remedy.
Heat helps to unclog the meibomian glands—tiny oil glands along the eyelid margin. These glands produce the oil layer of your tear film, which prevents tears from evaporating too quickly.
- Soak a clean cloth in warm (not hot) water.
- Place it over closed eyelids for 5–10 minutes.
- Gently massage the eyelids afterwards to stimulate oil flow.

Frequently Asked Questions
Does blue light permanently damage my eyes?
Current research indicates that blue light from digital screens is unlikely to cause permanent physical damage to the retina. However, it contributes significantly to digital eye strain and can disrupt your sleep cycle. Major bodies like the College of Optometrists suggest that while damage is unproven, comfort measures are still valid.
Do I need special computer glasses?
Not necessarily. If you already wear glasses, you should check your prescription. Sometimes, a prescription specifically optimised for the distance of a computer screen (intermediate distance) can help immensely. Blue light coatings are optional but reported by many to improve comfort.
Why do my eyes water if they are dry?
This is a reflex. When your eyes are dry and irritated from staring at a screen, your brain sends a signal to produce more tears to flush out the irritant. However, these reflex tears are mostly water and lack the necessary oils to lubricate the eye properly, leading to a cycle of watering and dryness.
Can diet help with sore eyes?
Yes. Nutrients like Omega-3 fatty acids, found in oily fish and flaxseeds, are crucial for tear production. Vitamins A, C, and E are also vital for overall eye health. Organisations like the RNIB provide excellent nutritional guidance for vision.
The Bottom Line
Sore eyes are your body’s way of telling you to slow down. While digital eye strain is rarely permanent, ignoring the symptoms can lead to chronic discomfort and reduced quality of life.
Prioritise your vision by implementing the 20-20-20 rule today. Adjust your workstation to support your posture, ensure your lighting is balanced, and never hesitate to reach for preservative-free eye drops when dryness sets in.
If your symptoms persist despite these changes, book an appointment with an optometrist. Your eyes are resilient, but they require care to function at their best in a digital world.
