Screens are part of everyday life. Whether you work at a computer, study online, check your phone, or relax with a show, long periods of screen use can leave your eyes feeling tired and uncomfortable.
Common signs of screen-related eye strain include dry eyes, blurred vision, headaches, sore eyes, and difficulty focusing. These symptoms are often linked to habits such as staring without blinking, sitting too close to a screen, or using a device in poor lighting.
The good news is that a few simple changes can make screen time more comfortable. Here are practical ways to protect your eyes and support better digital habits.
Follow the 20-20-20 rule
One of the easiest ways to reduce eye strain is to take regular distance breaks. Use the 20-20-20 rule:
- Every 20 minutes, look at something about 20 feet away.
- Look at it for at least 20 seconds.
This gives the muscles that help your eyes focus a chance to relax. A distant object, window view, or hallway can work well. If you often lose track of time, set a gentle reminder on your computer or phone.
Short breaks do not need to interrupt your entire workday. Looking away while listening to a meeting, waiting for a file to load, or taking a sip of water can help you build this habit.
Remember to blink
People tend to blink less when reading or concentrating on a screen. Less blinking can make your eyes feel dry or gritty, especially in rooms with heating, air conditioning, or moving air.
Make a conscious effort to blink fully and often. During a break, close your eyes for a few seconds, then open them slowly. This can help spread natural moisture across the surface of your eyes.
You can also reduce direct airflow. Avoid placing a fan or air vent so it blows straight toward your face.
Set up your screen comfortably
Your screen position can affect both eye comfort and overall posture. Try these basic adjustments:
- Place the screen about an arm’s length away.
- Position the top of the screen at or slightly below eye level.
- Keep the screen directly in front of you to avoid turning your head.
- Adjust the screen so you can read without leaning forward.
If you use a laptop for long periods, consider raising it to a comfortable height and using a separate keyboard and mouse. This can help you keep the screen and your hands in better positions.
For phones and tablets, avoid holding the device extremely close to your face. Increase the text size instead of moving the screen closer.
Reduce glare and harsh lighting
Glare makes your eyes work harder and can make text difficult to read. Look for reflections from windows, lamps, and overhead lights. You may be able to improve comfort by moving the screen, adjusting blinds, or changing the position of a desk lamp.
A matte screen filter can reduce reflections on some devices. You can also adjust the screen brightness so it matches the room. A screen that is much brighter or darker than its surroundings may feel uncomfortable.
Try not to use a bright screen in a completely dark room. A soft lamp in the room can create a more balanced level of light. However, avoid placing the lamp where it shines directly into your eyes or reflects off the screen.
Make text easier to read
Small or low-contrast text can encourage squinting and leaning toward the screen. Use your device’s accessibility settings to make reading more comfortable.
Helpful adjustments may include:
- Increasing font size
- Using higher contrast
- Zooming in on documents and web pages
- Choosing a clear, easy-to-read font
- Using dark mode when it feels more comfortable
There is no single display setting that works for everyone. Try different options and choose the one that lets you read without squinting.
Take regular movement breaks
Eye comfort is closely connected to the way you use your whole body. Staying in one position for hours can lead to tension in your neck, shoulders, and back, which may add to feelings of discomfort.
Every 30 to 60 minutes, stand up and move around for a few minutes. Stretch your shoulders, adjust your posture, or walk to get water. A longer break away from all screens can be especially helpful after several hours of work or study.
If possible, divide screen tasks throughout the day. For example, alternate computer work with printing and reviewing documents, phone calls, organizing materials, or other activities that do not require close screen focus.
Keep screens clean
Dust, fingerprints, and smudges can reduce clarity and increase glare. Clean your screen regularly with a soft, dry microfiber cloth or a product recommended by the device manufacturer.
Avoid spraying cleaner directly onto a screen. Moisture can enter openings and damage electronic components. If you use glasses, clean them with appropriate lens-cleaning materials rather than rough fabric or paper towels.
A clean screen may seem like a small detail, but clearer text can make reading more comfortable.
Use healthy habits with phones and tablets
Portable devices are easy to use for long stretches, especially when relaxing in bed or on the couch. To make this time easier on your eyes:
- Hold the device at a comfortable distance.
- Increase text size rather than bringing it closer.
- Take frequent breaks during scrolling or reading.
- Avoid using a bright screen in a very dark room.
- Keep the device at a height that does not require constant neck bending.
When watching videos, use a larger screen when practical. This may allow you to sit farther away and avoid holding a phone close to your face.
Support screen habits for children
Children also benefit from regular breaks, comfortable lighting, and good screen positioning. Encourage them to look away from the screen often and spend time on activities that involve movement and looking at different distances.
Create a screen setup that allows children to sit comfortably rather than using devices while lying down or holding them too close. Reminders work best when adults follow the same habits.
Outdoor play and non-screen activities can also provide a helpful balance during the day.
Know when to seek professional guidance
Occasional tiredness after a long screen session is common, but ongoing or worsening symptoms should not be ignored. Consider contacting an eye care professional if you regularly experience discomfort, persistent blurred vision, frequent headaches, eye redness, or difficulty focusing.
An eye care professional can discuss your symptoms and check whether your glasses, contact lenses, or screen setup need attention. Avoid changing prescription products or using someone else’s eyewear.
Build a routine that works
Protecting your eyes during screen time is less about avoiding screens completely and more about creating comfortable habits. Use regular distance breaks, blink often, reduce glare, adjust text size, and keep your screen at a suitable distance.
Start with one or two changes today, such as setting a break reminder and adjusting your screen brightness. Over time, these small steps can make long periods of digital work, study, and entertainment more comfortable.
