Set the adequate lighting

The simplest method to prevent eye strain from working a laptop in the darkness is to never use it in such a bad condition. Even a tiny quantity of illumination, such as a table lamp, can help to relieve eye strain. 

Additionally, while using the laptop, try to have regular pauses. After every 30 minutes of usage, take a break for a few minutes.

You might shut your eyes and take a few deep breaths. Or, try to look at something else to avoid focusing on one single thing for an extended period of time.

Also, limit the fluorescent lights. Many people claim that when they don't work under fluorescent lights, they experience significantly less eye strain. Use a LED light instead.

Also, ensure that the surroundings aren't too bright. It should have a similar brightness as the laptop's display.

Modify the screen brightness

You should lower the brightness of the laptop screen when functioning in the dark. It should fit the illumination in the place you're in.

It's the same as gazing straight into a spotlight for hours at a time if you turn the brightness at 100% in a totally dark area.

If you start noticing some spots or your eyesight becomes blurry, it’s time to decrease the brightness.

Increase the contrast

You can reduce the eyestrain substantially by raising the contrast on your monitor screen. The greater the contrast, the easier it is for your eyes to differentiate between different items on the display.

Words and other points will be simpler to see on the screen if the contrast has increased. As a result, your eyes can work less.

Here is how to increase the contrast on Windows:

  • Go to “Window settings”.

  • Choose the “Ease of Access” icon.

  • Click on the “High contrast” on your left hand.

  • Click on the slider to activate the high contrast.

Your eyes can detect the details on the screen easier with high contrast

Avoid glaring at the screen

You glare once the light goes straight into your eyes. This is the case of working with a laptop in the dark. You can't control this source of light, causing uncomfortable glares. Light reflection is another reason for glaring.

Adding softer lights in your working room is one of the ways to minimize glare. They guarantee that light reflects upwards before it reaches your eyes.

Task-based illuminating concentrates on the workspace as well. It does not brighten the entire area. If you worry about bothering others, this light also diffuses the light so that it just shines on your own workspace.

Increase the font size

It's hard to read the small letters in any situation. It's especially challenging in the dark. It puts a lot of stress on your eyes. The smaller the letter, the more difficult it will be to read it without focusing your eyes.

You need to adjust the font size till you can read the words at a distance of 14 or 15 inches from the computer monitor.

To increase the font size on Windows, please follow these steps:

  • Access to the settings of the display.

  • Look for the “Scale and layout” adjustment of text.

  • There are some options for you, such as 175%, 150%, and 125%. If they appear to be still too small or too big for you to read, go for the “Custom” settings.

  • Type your preferable option, such as 130%. The figure should be from 100 to 500.

  • Finally, apply the setting.Bigger letters are simpler to read

Activate the blue light filter

Blue light filtration is one of the most efficient techniques to guarantee that you have sufficient lighting for the laptop. 

The blue light reaches straight to the backside of your retina, causing macular degeneration. The light is harmful to your vision and can develop retinal issues.

The filter assures that your laptop has a pleasant light. It then eliminates eyestrain. The blue light filter will also prevent light radiation, allowing you to work in the dark while using your laptop for long periods of time.

Let’s learn how to activate the blue light filter on Windows:

  • Access to the Display settings.

  • Choose the “Night light” option.

  • Press the “Turn on now” button to run the night light.

  • There is a slider to adjust the temperature of the color. You can simply modify the level that is suitable for your eyes.

“Turn on” for the blue light filter


Using a laptop in the dark is truly harmful to your eyes. However, it’s unavoidable in some cases. You can still take action to minimize the consequences of that habit. 

Hopefully, you can save your eyes while still keeping on the good work with your laptop. If you have any questions, please feel free to ask.
