1. Choose the right brightness level

One of the simplest yet most effective ways to reduce eye strain is to adjust your screen brightness. When your screen is too bright or too dark, it can be uncomfortable and lead to faster eye fatigue. As lighting conditions change throughout the day, adjust your screen brightness accordingly.

During the day, when there is plenty of natural light, increase the brightness to match the ambient light. However, at night, lower the brightness to reduce the contrast between the screen and the surroundings.

2. Turn on Night Light mode

Computer screens emit blue light, the same high-energy light emitted by the sun. For someone who spends long hours working on a computer, blue light can be harmful, leading to eye strain and even disrupted sleep.

One thing to do to avoid this is to enable the Night Light feature in Windows. This feature reduces the amount of blue light emitted, making the screen easier to look at, especially at night.

Set the Night Light filter intensity to 30 so your screen isn't too warm but still reduces eye strain. Windows also lets you schedule Night Light to turn on automatically at sunset and off at sunrise, so you don't have to turn it on manually every day.

3. Schedule Dark Mode

Many people like to use Windows 11 in light mode during the day, but when night falls, the bright white background starts to look harsh. That's where switching to Dark Mode makes a big difference.

Since Windows doesn’t have a built-in option to automate this, you can use Auto Dark Mode to automatically switch between light and dark modes. Set Dark Mode to turn on at sunset and switch back to light mode at sunrise. Another great feature of Auto Dark Mode is the ability to assign keyboard shortcuts, allowing you to instantly switch between light and dark modes whenever you need to.

4. Choose the appropriate display ratio

While Windows automatically scales your display based on your resolution, the default setting doesn't seem to work well in some cases. Text, icons, and other elements appear too small, forcing you to squint constantly.

The default 100% scaling made everything too small, while 150% felt unnecessarily zoomed in. After some trial and error, setting the scaling to 125% struck the perfect balance — text was crisp and readable without sacrificing screen space.

If you're having trouble with readability, you should experiment with different scaling options in Settings > System > Display > Scale until you find the option that best suits your screen size and eyesight.

5. Increase the size of the mouse pointer and text

The default mouse cursor can sometimes be difficult to track, especially when using multiple monitors. To avoid having to constantly search for it, change the size of the mouse cursor in Windows and set its color to "inverted". This helps the cursor stand out on both light and dark backgrounds.

Similarly, increase the text size on Windows to 110%. This may not seem like a big change, but it makes a noticeable difference, especially for someone who works with text all day.

Incorporating these habits into your daily routine will significantly reduce eye strain, allowing you to work for longer hours without discomfort. In addition, following common-sense measures to avoid screen-related eye strain, such as maintaining an appropriate distance from your screen, taking regular breaks, and ensuring adequate lighting around your workspace, can also help.

If you struggle with eye strain while working on Windows, I highly recommend you try these tips and see which one works best for you. Your eyes will thank you!
