If you’re looking to purchase blue light glasses but are confused about which brand to get, you’re at the right place. In this post, we’ll look at blue light glasses from two of the top brands in the EMF shieldingEMF shielding refers to the practice of reducing the electromagnetic field (EMF) exposure in a particular area by blocking or altering the electromagnetic waves with barriers made of conductive or... space—SYB and DefenderShield—to help you choose the right ones for your needs.
Blue light glasses are one of the most discussed products since the pandemic. But why is everyone so obsessed with blue light glasses all of a sudden?
Why are Blue Light Glasses So Popular?
“As many customers started working from home last year, we have seen a significant rise in demand for these [blue light filter] lenses,” Neil Blumenthal, CEO of Warby Parker, has said. “Last April, we saw a sizable increase specifically for nonprescription blue-light-filtering lenses, and we’ve seen this trend continue throughout the pandemic.”
But why this sudden increase?
This has to do with a growing body of research linking blue light exposure with low-quality sleep and sleep disorders like insomnia.
A Bit About Blue Light
Blue light is one of the electromagnetic fields that sits in the visible light section of the electromagnetic spectrumThe electromagnetic spectrum encompasses the entire range of electromagnetic radiation, which varies in wavelength and frequency. This spectrum includes, in order of increasing frequency and decreasing wavelength, radio waves, microwaves,.... Usually, we’re exposed to blue light from the sun. And since the sun goes down in the evening, evolution shaped our circadian rhythm to reference blue light from the sun to regulate melatonin production in our body.

Good! Learn the one small change you should make right now.
In simple words, you feel tired in the evening because you aren’t seeing the blue light from the sun. The absence of this light is how your body knows that it’s time to slow down and get ready for a good night’s rest.
But the problem is that modern gadgets with LED screens emit the same kind of blue light the sun does. And since we don’t stop using our gadgets when the sun goes down, it affects our circadian rhythms. This creates problems like inability to fall asleep, waking up in the middle of the night, waking up tired, and more.

So, what can you do to protect yourself from the blue light that digital screens emit?
Well, trying to not use screens in the evening can do wonders. But obviously, this is not feasible for everyone. Besides that, screens aren’t the only source of our artificial blue light exposure. Fluorescent and LED lighting also emits significant amounts of blue light.
So, we needed another solution. And that’s how glasses with blue light filter lenses were born.
Blue light lenses are like any other lenses, just with an added layer of blue light filtering material. When you wear them, they protect your eyes from artificial blue light, helping revert your circadian rhythm to its natural state.
Shield Your Body (SYB) and DefenderShield (DS) are two of the market’s most-liked blue light glasses manufacturers. And in this post, we’ll compare our glasses with DS’s, so you can make an informed choice based on your needs.
But before that, let’s have a closer look at both companies.
Shield Your Body

A Deeper Comparison
Let’s look deeper at the features of SYB and DS’s blue light glasses.
Protection
The level of protection they provide is the most critical aspect of blue light glasses. So, let’s look at that first.
| Shield Your Body | DefenderShield |
Shield Your Body offers clear all-day glasses that block 35% of the blue light coming towards your eyes. You can wear these glasses all day without any changes in your body’s natural process. The reason our lenses are clear is that you need some amount of blue light to activate your biological systems during the day. During the day, blue light boosts alertness, helps memory and cognitive function and elevates mood. So, if you completely block blue light even during the day, your body won’t turn on activity mode, creating a different problem. Clear blue light lenses regulate the amount of blue light your eyes receive. So, you still get the amount of blue light you’re supposed to get from the sun. And since there won’t be sun in the evening, it shields enough blue light to help your body trigger its rest mode. | DefenderShield features four different types of glasses with two types of lenses. The yellow tint lenses block 50% of blue light, and the orange tint lenses block 99%. Although you can wear the yellow tint during the day, you may get better results if you keep your use situation-specific. This means you can wear your yellow tint glasses while using your computer or phone during the day and take them off when you’re not using them. The orange tint is strictly designed for nighttime use. Since you don’t need blue light at night, the orange tint helps your eyes settle down more naturally. |
Pricing
Both companies feature highly reasonable pricing.
| SYB Glasses | Price | DS Glasses | Price |
| SYB Blue Light Glasses | $39.00 | Universal Fitover Series | $49.99 |
| SYB Blue Light Clip-On Glasses | $12.00 | Versa Readers | $59.99 |
| Signature Series | $49.99 | ||
| Kids Series | $24.99 |
Customizability
Many of you reading this wear prescription glasses. And once prescription glasses are made, there isn’t much room for customization. So, adding a blue light filter layer to those glasses isn’t an option.
To solve this, SYB has clip-ons that you can simply attach to your prescription frames to turn them into blue light glasses.
And DS’s Universal Fitover Series sits comfortably over your prescription glasses to provide a blue light shielding layer on top of your prescription frames.
Ease of Use
Both glasses are incredibly lightweight, so you can get used to them fairly quickly. Here’s how glasses from both SYB and DefenderShield weigh.
| Shield Your Body | Weight | DefenderShield | Weight |
| SYB Blue Light Glasses | 0.011 lbs | Universal Fitover Series | 0.10 lbs |
| SYB Clip-On Glasses | 0.004 lbs | Versa Readers | 0.10 lbs |
| Signature Series | 0.10 lbs | ||
| Kids Series | 0.10 lbs |
A Small Investment for Your Health
Screens have become a part of our livelihood in the 21st century. So, taking measures to protect our eyes has become extremely crucial.
Although blue light’s effects may seem insignificant, in the long term, too much blue light exposure can cause severe and even chronic health problems. Getting blue light glasses is a small investment that goes a long way towards protecting you and your loved ones from these problems.
But how do you know which pair is the best for you?
Making the Choice
It’s pretty simple, actually. Look at your daily life and the amount of screentime you endure.
If your job requires you to sit at your computer all day or use your phone frequently, I recommend getting SYB Blue Light Glasses or SYB Clip-On Glasses (if you wear prescription glasses). As I mentioned, they’re clear lenses designed to be worn comfortably all day, every day.
You can also wear them in the evening. Because of the absence of sunlight, the clear lenses work perfectly well to prevent blue light from interfering with your circadian rhythm.
You might also prefer the aesthetic of clear lenses if you’re wearing them outside the home.
If you don’t use screens all day, you can go with DS’s yellow tint lenses to set your eyes to the natural rhythm if and when there’s a chance of heavy screen use.
Orange tint lenses should be strictly used in the evening only as they completely block blue light.
Conclusion
Whether it be from Shield Your Body or DefenderShield, be sure to get blue light filter glasses. As I already said, it’s a small investment toward your and your loved ones’ health and well-being.
Modern technology is amazing, and undeniably, it has elevated humanity to a level that people a mere 200 years ago could only dream of.
But, as Marian Wright Edelman once said, “In every seed of good, there is always a piece of bad.” Modern technology, as good as it is, also has a bad side.
Per research studies, prolonged technology use affects you physically, mentally, psychologically, and emotionally.
So, if you continue to ignore its bad side, sooner or later, it will hurt you.
