Nowadays, people spend hours every day in front of gadget screens — from smartphones to computers. This digital lifestyle inevitably affects our visual system. Eyes become tired, dry, and irritated; headaches and even sleep disturbances may follow. That’s why it’s crucial to know how to effectively relieve eye fatigue and keep your vision healthy for years to come. As noted by the Baltimore Chronicle, proper eye care should become a daily habit for every digital device user.
What Is Digital Eye Strain and How Does It Manifest?
Digital eye strain, also known as computer vision syndrome, is a group of symptoms caused by prolonged screen exposure. Our eyes are not designed to focus on lit-up screens at close distances for extended periods, which leads to strain.
Key symptoms of digital eye strain include:
- Blurred vision or trouble focusing
- Dryness or excessive tearing
- Gritty or burning sensation in the eyes
- Eye muscle tension
- Frequent headaches
These symptoms can lower productivity, reduce sleep quality, and negatively impact overall well-being.
Main Causes of Eye Fatigue During Screen Use
Eye fatigue can result from both physiological factors and working conditions:
- Infrequent blinking: while concentrating on a screen, we blink 2–3 times less often, causing dryness.
- Improper lighting: overly bright or dim environments increase strain.
- Incorrect screen position: the screen is placed too high or too close.
- Tiny text: forces the eyes to work harder to focus.
- Prolonged unbroken eye contact with screens: lack of breaks or focal shifts.
Effective Exercises to Relieve Eye Strain
Performing simple exercises regularly can significantly reduce eye strain and help prevent fatigue.
The 20–20–20 Rule
This rule is highly recommended by experts and means: every 20 minutes, look at something 20 feet away for at least 20 seconds.
Other helpful exercises:
- Eye rolls — slowly roll your eyes clockwise and then counterclockwise.
- Focusing — alternate focusing on a near object and one in the distance.
- “Figure Eight” — imagine a horizontal eight and trace its shape with your eyes.
- Closed eyes — close your eyes for 1–2 minutes and relax.
- Rapid blinking — blink quickly for 15 seconds to rehydrate the eyes.
Tips for Preventing Eye Fatigue
Prevention is the best approach to avoiding digital eye strain. Follow these simple but effective tips:
- Use anti-glare screens or blue light filters
- Adjust screen brightness to match room lighting
- Keep the screen 20–28 inches (50–70 cm) from your eyes
- Take breaks every 30–40 minutes
- Stay hydrated — water is essential for eye health
- Use a humidifier if working in air-conditioned spaces
Nutrition for Eye Health Support
In addition to external care, it’s important to support your eyes from within. They need vitamins and minerals to protect the retina and reduce oxidative stress.
Best foods for eye health:
- Carrots, pumpkin, spinach — rich in beta-carotene
- Blueberries, blackberries — powerful antioxidants
- Eggs — contain lutein and zeaxanthin
- Fish (salmon, tuna) — high in omega-3 fatty acids
- Nuts and seeds — contain vitamin E and zinc

When to See an Eye Doctor
If digital eye strain symptoms persist despite following hygiene practices and doing eye exercises, it’s essential to consult an eye care professional. The doctor may:
- Conduct a vision check and prescribe blue light filter glasses
- Recommend appropriate moisturizing drops
- Screen for any underlying eye conditions
Don’t ignore worrying symptoms — vision is one of our most valuable senses.
Additional Relaxation Methods for Eyes
In addition to traditional techniques, there are alternative ways to restore eye comfort:
- Acupressure on points near the bridge of the nose and under the eyes
- Cooling masks or chamomile compresses
- Eye yoga, which combines movement and breathing
- Aromatherapy for general relaxation
