Screen Time & Eye Strain: How Your Computer Setup Matters

If you're spending most of your day staring at a screen, you've probably felt that familiar ache behind your eyes by late afternoon. Eye strain from computer work is incredibly common, but the good news is that it's mostly preventable with a few simple adjustments to your setup.

Whether you're working from a cramped desk in a Stockbridge flat or running a business from a home office in Morningside, the way you arrange your screen and lighting makes a huge difference to how your eyes feel at the end of the day.

Monitor Distance and Height

Your monitor should sit at arm's length away from where you're sitting, which is roughly 50 to 70 centimetres. If you're leaning in close, you're straining your eyes unnecessarily. The top of your screen should be at or slightly below eye level when you're sitting up straight. This means your eyes naturally look slightly downward, which reduces strain on your neck and shoulders too.

If your laptop is the main screen you use, consider getting a separate monitor and keyboard. Laptops force you to look down and sit too close, which causes all sorts of problems over time. A cheap external monitor from any electronics shop can transform your setup and cost far less than dealing with persistent headaches and vision problems. Pop it on a small stand or even a pile of books to get the height right.

Lighting: The Silent Culprit

Most eye strain comes from poor lighting, not the screen itself. Harsh overhead lights or bright sunlight reflecting off your monitor force your eyes to work overtime. Ideally, your room should have soft, indirect lighting that doesn't create glare on your screen. If you work near a window in areas like Leith or Corstorphine where you get good daylight, use a desk lamp with a shade to balance things out rather than relying on the sun alone.

Position your monitor so windows are to the side of it, not directly behind or in front of it. If you can't avoid glare, anti-glare screen protectors or monitor hoods are affordable solutions. And get yourself a decent desk lamp with adjustable brightness. You want enough light to see your keyboard and desk, but not so much that it bounces off your screen.

The 20-20-20 Rule

Every 20 minutes, look away from your screen at something at least 20 metres away for at least 20 seconds. This gives your eye muscles a proper break. If you're in an office or flat without a distant view, just looking across the room at a wall is better than nothing. It sounds simple, but it genuinely works.

Set a quiet reminder on your phone or computer to give yourself a nudge. Many people find that when they actually do this consistently, their eye strain drops dramatically within a week or two. It costs nothing and takes seconds, but most of us forget to do it without a prompt.

Screen Settings That Help

Your monitor's brightness shouldn't be brighter than your surroundings. A common mistake is having a brilliant screen in a dimly lit room, which exhausts your eyes. Most modern monitors let you adjust brightness, contrast, and colour temperature. Warmer screen tones (reducing blue light) especially in the evening can help you feel less fatigued and sleep better.

Windows and Mac both have built-in settings to reduce blue light automatically. On Windows, look for 'Night Light' in your display settings. On Mac, it's called 'Night Shift'. These gradually warm up your screen as the evening approaches, which is kind to your eyes and helps your sleep cycles. If you spend a lot of time on video calls, make sure your camera isn't positioned too high, which forces you to look up constantly.

Blink More and Moisturise

When we focus on screens, we blink far less than normal. This lets our eyes dry out, which creates that scratchy, uncomfortable feeling. Consciously remind yourself to blink regularly, and if your eyes feel dry, over-the-counter lubricating drops help enormously. They're cheap and work quickly.

If you wear glasses or contact lenses, make sure your prescription is up to date. Many people have a prescription that's fine for general use but not quite right for screen distance. Your optician can give you computer glasses if needed, which are specifically tuned for the distance from your eyes to your monitor.

Your Desk Setup Matters Too

Your chair height is as important as your monitor height. Your feet should rest flat on the floor or a footrest, with your thighs parallel to the ground. Your elbows should be at roughly 90 degrees when typing. If you're hunched or twisted, your whole body gets tense, which makes eye strain worse. Spend a few minutes getting this right and you'll notice the difference immediately.

Keep your desk tidy enough that you're not constantly moving your head and refocusing between your screen and papers. A document holder next to your monitor helps if you're typing from printed material. The less your eyes have to adjust focus, the less strain you experience.

When to Get Your Setup Checked

If you've made all these adjustments and eye strain persists, it's worth getting your setup looked at properly. Sometimes it's something obvious like a monitor sitting too high or lighting coming from the wrong angle, but it's easy to miss when you're living with it every day. A fresh pair of eyes and some quick adjustments can make a real difference.
