Did you know that having the wrong colors for your computer screens can cause strain on your eyes?

It’s true! In our technology-obsessed world, many of our devices with screens are causing a modern form of eye strain that, when left unchecked, can lead to major eye and medical problems such as blurred vision, headaches and macular degenerations.

Luckily, there are many easy ways to prevent this, and applying them will ensure that your eyes stay healthy and strain-free throughout your lifetime.

How Colors on Your Computer Screen Cause Strain for Your Eyes


The spectrum of colors from your computer screen are varied, and so are these colours’ wavelengths. Certain colors on the spectrum, like blue light, are harder on the eyes because they have shorter wavelengths and are high energy.

Blue light also flickers more frequently on computer screens’ LED backlight controllers, and this flickering causes more eye fatigue than other colours like red or orange.


Blue light also reaches deeper into the eye, causing damage to the retina. In fact, Blue light can be so detrimental to the eyes, that several medical studies, including a study by Molecular Vision in 2016, have found that it can lead to macular and retinal degenerations.

Blue Light Sources


    The sun is the largest source of blue light for our eyes, but there are many other sources too, including:

  • Computer screens
  • Smartphone screens
  • Tablet screens
  • Fluorescent lights
  • LED lights
  • Flat screen LED TVs

  • Physical fatigue
  • Headaches
  • Blurred vision
  • Red eyes
  • Eye twitching
  • Eye pain

Other Causes for Eye Strain

While the colors for your computer screen affect your eyes, there are several other causes too. Common ones include:

    • Poor lighting or too much light


    • Glare


    Too much screen brightness

How to Correct and Reduce Eye Strain


The most important action you can take if you experience any of these symptoms is to see a doctor and an optometrist.

Your doctor can run tests to see if there are any other medical issues causing the problems, but only an optometrist can diagnose digital eye strain or more severe blue-light related issues such as macular degeneration.

In Vancouver, offer comprehensive eye exams for under $90, and these exams are often covered by medical insurance—so it’s worth it to get one at least every year.

Booking an Eye Exam

Comprehensive eye exams can reveal a lot about your environment, health and daily habits that are causing your eye strain.

In particular, the National Institute of Occupational Safety and Health recommends that computer users should have an eye exam before they start working on a computer and once a year thereafter.

It’s also important to note some important environmental and computer-related details before your exam. In particular:

  • Note how much computer and screen time you engage in on a daily basis
  • Note how close you are to your computer screen on average
  • Note the type of lighting you use at work and at home
  • Note the amount of exposure you get to sunlight, and the type of sun protection you use for your eyes

How Different Colours on Your Computer Screen Can Reduce Strain

Considering the negative effects of blue light on your eyes, it’s important to manage the colors you see on your computer screen.

You will want to reduce the color temperature on your display, as this lowers the blue light emissions, and is easier on your eyes.

On Macs, these settings are in System Preferences which you can find in the Applications Folder.

However, you can save yourself a lot of trouble and simply find one of the many apps, programs or filters online that reduces blue light, such as f.lux. Many smart devices come with settings that reduce blue light too.

2. Best Colors and Combinations for a Computer Screen to Use on Eyes

It’s also important to pay attention to the computer screen color combinations you use on a daily basis. The best color combination to use is black text on a white background.

If you must use other colors, make sure they consist of dark text on light backgrounds, and not the other way around.

3.Worst Color Combinations to Use on a Computer Screen

The worst color combinations to use consist of dark text on dark backgrounds. Similarly, low-contrast text on low contrast backgrounds, or low contrast text on busy/multi-coloured backgrounds will cause more strain for the eyes.

4.Other Ways to Prevent Eye Strain

Use proper lighting: When working on a computer, it is best to use ambient, low-intensity lighting. You should also reduce the amount of bright light from outdoors by closing the curtains or blinds, especially on sunny days.

Fluorescent lights also emit blue light and thus aren’t good for your eyes while working on a computer. Instead, try and use a low-light lamp or move somewhere far away from the direct source of lighting.

Minimize glare: Avoid reflective surfaces when using your computer when possible.

Some ways to do this include getting an anti-glare screen or filter for your computer and devices, or moving to rooms with dark coloured walls when using your screen device. You can also purchase anti-glare glasses with anti-reflective (AR) coating.

Eye strain is a common occurrence in our modern world, but it’s easy to diagnose and treat with proper medical assessments and some easy daily adjustments to your routine. To learn more about booking an eye exam in Vancouver,click here.
