Monitor Too Bright: Side Effects And How To Fix It 

Monitor Too Bright

Do you know that adults spend an average of 11 hours on screens every day? These include screen time on a computer system, mobile device, and TV combined.    

Frankly, technology has done us a world of good for communication and getting several tasks done with ease. But we can’t say the same for our health. 

Increased screen time can be a significant issue health-wise. And it could be worse if your monitor’s screen is just too bright. In this article, you’ll learn about what monitor too bright means and how to fix it. Read on! 

Understanding The Brightness Of Your Monitor

Of all the visible lights to the eyes, blue light has the shortest wavelength. This means that it carries the greatest energy level. Thus, exposure over an extended period can adversely affect the eyes’ photoreceptive retina cells. 

This makes having a bright monitor dangerous. To be clear, the blue light emitted by devices such as monitors and mobile devices isn’t harmful to the eyes. Instead, we experience what we call Digital Eye Strain or DES. 

Overexposure to bright screens causes DRS, which manifests as headaches, blurred vision, and refined strained eyes. 

So if you’ve been wondering if too bright screens affect the eyes, the answer is Yes. 

Since many manufacturers know this, they have invested heavily in research and development to develop newer technologies that minimize the adverse effects of their digital displays. 

Kindle, for example, tries to mimic the brightness and look of a regular hardback book. This is a deliberate design that enhances nostalgia and limits the adverse effects e-readers suffer from reading on bright screens for too long. 

What Is The Best Screen Brightness?

Unfortunately, it is impossible to say that any particular brightness is best for everyone. This is because your brightness will vary based on Monitor screen type, settings, and your environment. 

Let’s start by learning how screen brightness is measured. The brightness levels are measured influx, Lumen (lm), and candela. 

While using the recommended brightness by your monitor is helpful most times, it is comparably unhelpful. That is because the adaptive brightness of our screens is determined using an average scale gotten from research. A 50% brightness setting on one monitor will differ based on the monitor model. 

How To Adjust Your Monitors Light

On most monitor keyboards, there are shortcut keys that you can use to adjust your screen brightness. There is one to increase the brightness and another to reduce your screen brightness.

These keys are usually found on the F-keys that appear above the number row of your keyboard. To adjust your brightness, locate the shortcut key that corresponds with the action you want to take. It should be a sun logo. Press it until you’ve achieved your preferred brightness.

These are standard function keys which means you may have to press the fn key before using them.

On windows, you can adjust your display brightness from within the OS itself. In some cases, it is possible that the FN keys arena isn’t working as it should, or you don’t have them, to begin with. 

How to Adjust Your Screen Brightness on Windows

On Windows 10, you should see a quick brightness slider in the action center. 

It is also possible to change the display brightness from the Windows setting. This is valuable if the keyboard lacks such keys. Or you’re utilizing a tablet and have to do it within the software.


  • Click or tap on the notification icon on the right side of the clock on the taskbar. If you can’t see the slider, click the expand option above the grid of tiles. 
  • Click the slider and drag it across until you’ve gotten a brightness level you like. 

For older versions of the Windows OS, you should click on the battery icon and select adjust battery settings. A pop-up menu will appear showing the various battery modes and the brightness levels for each model. There is also a central brightness meter, so you can reduce your screen’s brightness level now without changing any of your settings. 

Another method will be to: 

  • Open the Control Panel
  • Click Hardware and Sound,
  • Select “Power Options.”  Once you do, you’ll see a “Screen brightness” slider at the bottom of the Power Plans window.
  • Click and adjust until you achieve a brightness you’re comfortable with. 

Low Lcreen Brightness Vs High screen Brightness; Which Is Better For The Eyes? 

It’sIt’s normal for us to wonder which is better for the eyes, bright images or very dim ones on our screen. 

When asked this question, many users seem to prefer low screen brightness. This answer seems to make more sense because low light reduces the harsh effects of blue light. But dim light also causes damage. It most likely does more harm than good. 

As we mentioned earlier, the best screen brightness of a monitor depends on the room’s ambient light you’re working in. 

That means using a brightness level considered too low can be equally harmful to your eyes. 

A secret to knowing just how bright is bright enough is by setting your screen to be just as bright as the room. You can do this by putting an object in front of your monitor as you gradually increase your brightness level. Once you notice the screen light becoming visible on the object, you should stop. 

At that point, you have achieved the best brightness level for that period.

What To Do When You Can’t Control The Brightness Of Your Screen

If, for some reason, you’re working in front of a screen that is too bright, here are a few ideas that can help: 

Eye exercise:

While you wouldn’t find equipment for this in the gym, you can train your eyes and muscles. If you work your eyes for too long, your muscles get tired, and you will begin to experience spasms. They are uncomfortable and a bit scary as your eyes lids close or behave irrationally. When this happens, let them rest and move away from your screen. Focus on any object at least 20ft away from where you stand. Do this for 30 seconds every 20 minutes. 

Using Blue light filter:

You can also use a blue light filter. There are filter screens for your monitor screens, or you can get anti-blue light glasses. They are cheap and easy to get. They provide decent protection from blue light and screen glare. 

Monitors now come with night light settings that help protect your eyes from blue light. You can activate your night light in Windows by opening System Settings > Display > Brightness and Color > Night Light Settings. Here you can also increase or reduce the intensity of the night light at certain times of the day.

How To Reduce Eye Strain 

Monitor position:

Your monitor should be positioned 20-30 inches away from your face, and your eye level should be the very top of your monitor. Additionally, if you can adjust your monitor height, stack some hardcover books beneath it. You can also change the height of your chair. 

For comfort, you should be slightly looking down to see the center of your screen (between 15 and 20 degrees).  

Text size and color: 

A good rule of thumb is that your screen text should be three times the smallest size you can read at a normal viewing position.

The human eyes see white on black or a slightly yellow background better than almost any other color combination. 

Regardless of your color combination, it would be best to avoid low contrast text/background color schemes. 


It is important to remember that your monitor screen should neither be too bright or too dim. Keeping things balanced will help you use your monitor better and longer without experiencing DES.
