Anti-blue light – screen protector, app filter, or light blocking glasses?

Should you use an anti-blue light screen protector, app filter, or light-blocking glasses? It is an essential question asked by many people who worry about their eyes health when using electronic devices for a prolonged period.

Your eyes are an important organ like other organs and tissues in your body. Research shows that 80% of what you perceive in the environment is through your eyesight. When you protect your eyes from blue light, you reduce a wide range of issues, including:

  • Eyestrain
  • Headaches
  • Vision loss
  • Fatigue
  • Blindness
  • Cataracts
  • Diabetes
  • Cancer

The question is: is the anti-blue light screen protector effective? What about app filters and blue-light-blocking glasses? In today’s article, I will discuss these devices and highlight their advantages and disadvantages to ensure you use to choose the right product.

Screen Protector

Smartphones are the most widely used devices worldwide because they are the primary means of communication. However, smartphones, computers, laptops, and other screen-based devices can emit blue light and affect your eyes’ health.

Therefore, it is worth investing in an anti-blue light screen protector to block or mitigate the adverse effects of artificial blue light on your eyes and skin. Here are the pros and cons of an anti-blue light screen protector. Continue reading!  

Advantages and Disadvantages of Screen Protector

A phone screen or computer screen protector can improve your eyesight by protecting your eyes from harmful blue light and UV light. Not only do they protect your eyes, but they also prevent your phone’s screen from scratches and cracks.

Different types of screen protectors available on the market are PET film screens, TPU screens, and tempered glass screen protectors. PET film screen protectors are thin and lightweight, offering additional protection to your phone and prevent blue light from penetrating your eyes.

However, these protectors are not crystal clear, causing a blurry display and may damage your eyes. Likewise, these protectors are prone to discoloration from UV and blue light from sun rays. Using these protectors can accumulate extra oil on your phone screen from your fingers.

On the other hand, TPU screen protectors are thin, lightweight with sharp clarity, allowing for streamlined display. These screen protectors have an affordable price and may protect your eyes from blue light.

However, the downside of these screen protectors is that they are highly prone to scratches. Thus, they are not worth your investment when it comes to protecting your phone screen and eyes from blue light.

App Filters

Many smartphone and computer applications filter or mask blue light. These apps use cutting-edge technology to shift the color tone and prevent the blue light from penetrating your eyes. Although these apps can reduce blue light emitting from your computer or smartphone, they are not fully effective.

Not all apps are effective and may cause digital eye strain by distorting true color and reducing contrast. Because app filters focus more on acquiring orange, yellow, red sheen on the screen, it is difficult for you to focus on your eyes on the screen. 

Advantages and Disadvantages of Blue Light Filter Apps

Blue light filtering apps are an effective solution to protect your eyes from blue light and strain. Some high-quality apps, such as Twilight, Easy Eyes, Blue Light Filter, Darker, Night Shift, Blue Light Filter Pro, Blue Light Filter and Night Mode, and Blue Light Filter by Hardy-infinity do not cause discoloration or distortion. So, these premium apps are effective against eye strain even when you use your computer or phone for a long time.

On the other hand, when you use less popular or free apps to filter blue light, they can cause even more eye strain due to discoloration and contrast distortion. LED light backlights your phone or computer that contains both blue and white light. App filters do not filter out these waves and cause eye strain, retinal damage, vision loss, and cataracts.

Blue Light Blocking Glasses

Unlike screen protectors and app filters, blue-light-blocking glasses are more effective, offering unique eye protection solutions. These glasses have specialized and well-crafted lenses that can filter out blue light emitting from digital devices or screens. It is crucial to invest in high-quality glasses with specialized lenses to reduce the glare that can damage your retina.

Advantages and Disadvantages of Blue Light Glasses

There are numerous benefits of wearing blue-light-blocking glasses. Not only do these glasses protect your eyesight and prevent retinal damage, but they also allow you to use screens for a long time without damaging your retina or disrupting your circadian rhythm.

People who use blue-light-blocking glasses can filter the light between six and eight nanometers and reduce the risk of mental health conditions, such as stress, depression, and anxiety. These glasses also protect photosensitive retinal ganglion cells in your eyes.

These cells communicate with your brain and control the circadian clock in the hypothalamus, ensuring you have a good night’s sleep. Blue light-blocking glasses also improve your brain function, causing them to release more melatonin to enhance your sleeping patterns at night.

Moreover, wearing these glasses can enhance your mood by preventing blue light from disrupting your limbic system functions. So, if you have bipolar disorder and use computer screens for a prolonged period, it is wise to wear blue light glasses to avoid disrupting your mood.

The only downside of blue-light-blocking glasses is that you see everything in a yellow tint. Thus, it can cause difficulties for some people to read screens and may cause scotopic vision loss, but this occurs rarely.

Final Words

The choice of using an anti-blue light screen protector, app filters, or blue light glasses depends on your personal preferences. However, if you are keen on your eye health and want to reduce exposure to glare, we recommend using blue light glasses because they offer numerous advantages and have fewer downsides with low occurrence rates.
