What are blue light glasses and do they really work?

How many hours do we spend in front of a digital screen per day? Recent research indicates it’s actually far more than you would think!

That’s right, according to Forbes, on average, we adults spend more than 12 hours a day in front of our smartphones, tablets, TVs and computers. No wonder blue light exposure has become such a hot topic!

One of the best and easiest ways to protect yourself from overexposure of this type of light is by using specifically designed blue-light blocking glasses. However, there are still a lot of misunderstandings about how they really work and how effective they can be. 

At Barner, we know that wearing blue light glasses can have a positive impact on our digital generation’s overall well-being, that’s why we want to share our expertise with you.

What is blue light?

Blue light refers to a portion of the light wavelength that can be seen by human eyes and that is considered to be potentially tiring at the retinal level when exposed to it on a regular basis.

This blue-violet light can be typically found within the 380-500 nm wavelength, and is naturally emitted by the sun, and artificially emitted by digital screens. It is however, between the 415 nm to 455 nm where it is considered to be strongest.

Blue light surrounds us in our everyday life. Did you know that the reason we see the sky as being blue is actually because of this type of light? When these shortwaves from the sun strike against air molecules, it creates what our eyes interpret as an infinite blue sky. 


Blue light is also responsible for regulating the circadian rhythms of our bodies: the sleep/wake cycles. That’s why, when overexposed to blue light, especially at night, sleep routines can be seriously affected, and computer vision syndrome symptoms might appear.

Understanding HEV Light

HEV, another technical term for Blue Light, stands for High-Energy Visible Light, because it is a short wavelength which produces the highest amounts of energy. The HEV light can be found near the ultraviolet (UV) end of the spectrum.

One of the main effects of HEV light on people’s vision is that it can cause eye strain and dry eyes after prolonged periods of exposure. This is due to the shorter wavelengths and greater energy of HEV which can be a result of the flashing, rapidly changing glare that our digital devices emit, which forces the eyes to focus harder.

Eye strain and dry eyes. Typical symptoms include: a burning and stinging sensation, eye irritation and redness and sensitivity to light. They can also be accompanied by the so-called Computer vision syndrome which is characterized by headaches, blurred vision and neck and shoulder pain. 

• Disruption of sleep cycle: According to an experiment conducted by Harvard researchers, after more than 6 hours of exposure to blue light (compared to the same exposure to green light), they found that  blue light had shifted circadian cycles by twice as much as the green light (3 hours versus 1.5 hours). HEV light had also suppressed double the amount of melatonin than the exposure to green light had. (The hormone melatonin is one of our best friends when it comes to helping us fall asleep).

How do Barner’s lenses block blue light?

How do Barner’s lenses block blue light?

All the glasses in our collection have lenses with a coating that has been carefully developed to protect our eyes against the side effects of prolonged blue-violet and LED light exposure. 

Our high quality organic CR39 lenses block 40% of the blue light on the 430-450 nm spectrum and 100% of the blue light at 410 nm. 

Barner’s lenses use two technologies: the first one reflects the blue light and the second one absorbs it. The effects are quickly noticeable: the eyes are more rested, relaxed and more comfortable when using digital devices. 

With the digital generation in mind, we have designed the clearest lenses with optimum protection, ideal for people who do color-sensitive work (like graphic designers, video/photo editors or any other profession that needs to see true color). 

Our protection against artificial blue light creates a perfect balance between color perception and blue light filtering.

Less than a hundred years ago, the idea of protecting your skin from potentially harmful UV rays first became a big issue. By the 1980’s we had a far better understanding of the damage that can be caused to the skin. Could you imagine now spending entire days under a sweltering sun without any protection at all?

In our busy digital lives, we all spend numerous hours in front of our screens, and until very recently, we were doing so unprotected. Now we have more knowledge about the potential side effects, so it seems like a no-brainer to do everything within our power to protect our vision. Our computer glasses are stylish, very comfortable and there’s no need for a prescription!

Even though this is a relatively new concept, there is a fast-growing community of digital professionals who are fans of Barner’s blue light glasses.

• Should you wear blue light glasses?

Blue light is present in our everyday life and it is an important source of energy from the sun. However, with our increasingly busy digital lives, we are becoming more and more exposed to the artificial blue light that is emitted from our screens. 

Blue light glasses are a great option to prevent eye strain and dry eyes and to ensure that your sleep pattern is not affected by the overexposure to the blue light of our digital devices. 


• Do blue light glasses really work?

We spend most of the day in front of screens: phones, tablets, TVs, computers, and until recently we have been doing so unprotected. The benefits of using blue light glasses to avoid eye strain and disruption of sleep cycles are becoming more and more popular

Could you imagine now spending entire days under a sweltering sun without any protection at all?

Protecting your eyes from overexposure to blue light has great benefits

✔   Better focus 

   Reduces glare & eye strain

✔   Reduces Computer vision syndrome symptoms

✔  Improves posture and well-being

✔  Better sleep cycles

• Do you need a prescription for blue light glasses?

Blue light glasses do not require a prescription. They can be used by anyone that wants to add an extra layer of protection to their eyes from the tiring light emitted by our screens. 


Barner lenses have been specifically designed for people who do color-sensitive work. Other than the faintest yellowish perception against white backgrounds, Barner’s lenses successfully minimize any color distortion, with digital professionals reporting that their eyes felt more rested after long working days.
