Focusing on any screen all day can bring on headaches, eye strain, and fatigue. If your work keeps you on your devices with few chances to step away, glare is one of the first things worth fixing — it's a common factor when people tell us about this kind of discomfort.
The short answer: to reduce screen glare, keep your screen clean, position it so windows and bright lights are beside you rather than in front or behind, control the light with shades and task lighting, and add an anti-glare filter or monitor arm if reflections persist. Here's how each fix works.
Key takeaways
- Screen glare makes your eyes work harder to see past reflections and bright spots, which feeds headaches, eye strain, and fatigue.
- Start with free fixes: clean the screen, angle it away from windows and overhead lights, and use shades or curtains.
- An anti-glare screen filter diffuses light and cuts mirror-like reflections in challenging or changing lighting.
- A monitor arm lets you reposition the screen as daylight shifts, and a glare-free task lamp replaces harsh overhead light.
- Breaks still matter — step away from the screen when discomfort starts.
Glare doesn't only affect your eyes. When you lean, tilt, or crane to see past a bright spot, your posture follows — so reducing glare is part of the same picture as the foundations of good posture. For the broader set of eye-care habits, see our guide to preventing eye strain at work.
How Does Screen Glare Cause Eye Strain?
Screen glare causes eye strain by forcing your eyes to work harder to see past reflections, bright patches, and washed-out contrast. Your eyes constantly adjust between the bright spots and the content you're trying to read. Over a full workday, that extra effort shows up as headaches, tired eyes, and mental fatigue. Just because your eyes sit comfortably in their sockets doesn't mean they aren't straining.
How Do You Reduce Screen Glare?
You reduce screen glare by tackling the light at its source, then adjusting the screen itself. Work through these fixes in order — the first ones cost nothing.
Keep your screen clean
Dust and smudges scatter light and add haze, which increases glare and makes focusing harder. You may not realize you're straining to see past a light layer of dirt, but it can contribute to headaches throughout the day. Wipe the screen regularly with a cleaner made for displays.
Control the lighting around you
Make sure there aren't bright lights overhead or nearby reflecting off your screen. Keep your monitor away from windows, where outside light creates harsh contrasts or washed-out areas on the screen; ideally, position the desk so windows are to your side. In offices with lots of windows, use shades or curtains to block direct sunlight. If overhead lights are the culprit, dim them where you can and light your work with a glare-free desk lamp such as the Humanscale Horizon 2.0.
Use an anti-glare screen filter
An anti-glare filter diffuses light so the screen is easier to see in challenging or changing indoor lighting. It also reduces the mirror-like reflections from bright indoor lights that glossy screens tend to pick up. Filters are especially useful when you can't move your desk or control the room lighting, such as in shared offices.
Reposition your screen
Consider moving the screen to a position that better fits your height and the way your workstation is set up. A slight backward tilt often moves overhead reflections out of view. A monitor arm gives you the flexibility to reposition your monitor as light conditions change through the day, rather than living with whatever angle the stand allows.
Screen Glare Quick Fix Guide
| Glare source | What you'll notice | Fix |
|---|---|---|
| Window behind you | Bright reflections across the screen | Turn the desk so the window is to your side; close blinds |
| Window behind the monitor | Squinting against a bright background | Move the monitor or use shades or curtains |
| Overhead lights | Bright spots near the top of the screen | Tilt the screen slightly, dim or switch off overheads, add a task lamp |
| Dusty or smudged screen | Hazy image, constant refocusing | Clean the screen regularly |
| Glossy screen finish | Mirror-like reflections of the room | Anti-glare screen filter |
| Changing daylight | Glare that comes and goes through the day | Monitor arm for quick repositioning |
Do Breaks Help With Glare and Eye Strain?
Yes — even with glare under control, your eyes need regular rest from close focus. When you start to feel discomfort, try taking 15 to 20 minutes away from your monitor or other devices. Shorter, more frequent pauses help too; here's how often to take breaks during the day.
Eye strain and mental fatigue often travel together, so if your afternoons feel heavy, it's worth reading about why you feel drained at work. AskErgoWorks provides ergonomic solutions for the whole body to create a safer, healthier workplace, and that includes your mental state, not just physical stressors.

Frequently Asked Questions
What is the fastest way to reduce screen glare?
Clean your screen, tilt it slightly away from overhead lights, and close blinds on any window in front of or behind you. These free changes resolve a lot of glare in minutes. If reflections remain, add a task lamp, an anti-glare filter, or a monitor arm.
Do anti-glare screens really work?
Anti-glare filters diffuse incoming light and reduce mirror-like reflections, which makes the screen easier to see in bright or changing lighting. They're most helpful when you can't control the room's lighting or move your desk.
Where should my monitor be in relation to a window?
Place your monitor so the window is to your side rather than directly in front of or behind the screen. A window behind you reflects on the screen, and one behind the monitor creates a bright background that makes your eyes work harder.
Can screen glare cause headaches?
Glare can contribute to headaches because your eyes strain to see past reflections and bright spots throughout the day. If headaches continue after you've reduced glare, see an eye care professional.
