Do blue blocker glasses help for real or are they just a marketing gimmick?

If you have been googling blue blocker glasses, you must have already read lots of articles about blue blocker glasses online. This means you must have seen the two factions having contrasting views about these glasses. The first faction comprises people who say blue light glasses and the second who believe that blue blocker glasses don’t serve any practical purpose.

But what are blue blocker glasses and how do they work?

Blue light is visible light emitted by various digital devices, including laptops, smartphones, tablets and computers. Unlike UV light, blue light can pass through our cornea in our eyes and reach the retina.  Blue blocker glasses have protective coatings that filter out or absorb this blue light and prevent it from entering the eye.

Now that we know the basics, let’s move further. Which of the two groups say the truth? Is it the one that believes blue blocker glasses help or the ones that believe the opposite?

The truth is that blue blocker glasses may or may not help. Confused? Let us address the major claims about blue blocker glasses and explain things one by one.

Claim #1 – Blue light causes retinal degradation.

  •         Where did it come from?

A study conducted in mice showed that when they were exposed to High Energy Visible Blue Light (HEV Blue Light), their retinas degraded faster. This made many believe that it is the same for humans too! And that this retinal degradation also increases chances of age-related macular degeneration.

  •         Is it true?

Not exactly. The experiments conducted on the mice used a much higher intensity of blue light than we’re exposed to when we use our digital devices! This means that we’re more likely to develop age-related retinal degradation due to other factors when compared to the effect of blue light from the screens.

Unfortunately, this claim was so widely marketed as the truth that many ophthalmologists now believe that blue blocker glasses don’t work at all.

Claim #2 – Blue blocker glasses can help you regulate your circadian rhythms.

  •         Where did this come from?

Research shows that blue light from digital screens suppresses melatonin production and disrupts our sleep cycles.

  •         Is this claim true?

Blue light is everywhere. The sun also emits blue visible wavelengths and this light helps us become more alert. But why is it that exposure to blue light from screen usage can impact the quality of sleep? This is because a lot of us frequently use our phones/tablets just before going to sleep, meaning we’re stimulating our body to stay awake even when it’s time to sleep. And yes this is a case in which blue blocker glasses have been known to help.

Claim #3 – Blue blocker glasses relieve eye strain.

  •         Where did this come from?

We’re no strangers to the fact that long time on digital screens can cause red eyes, dry eyes, eye strain and headaches. Some believe that these symptoms of Digital Eye Strain or Computer Vision Syndrome (CVS) are caused due to the blue light emitted from the screens. This implied that wearing blue-blocking glasses can help reduce the strain.

  •         Is this claim true?

We don’t know for sure. While some people have reported reduced symptoms after wearing blue blocker glasses, others have felt no difference at all. This means that if you are buying a pair of blue blocker glasses to reduce your symptoms of CVS, it may help a lot or not at all.

So why not try blue blocker glasses for yourself?

If you are curious whether blue light protection glasses really work, why don’t you buy a pair and see for yourself. For those who prefer buying prescription glasses online, you should consider buying a pair of X-Blue lenses from Specscart. Buying from Spescart means you’re going to get the best deals of the eyewear market. 

So, buy a pair of blue blockers with designer frames and see if they work for you!
