It has happened to everyone: those who spend many hours in front of the PC screen, sooner or later find themselves with eye strain.
The term CVS, from the English Computer Vision Syndrome, defines a series of disorders that include redness, tearing or dry eyes, photophobia, headaches, and pains in the neck or back.
It is also evident that the position of the device, the distance from the screen, the lighting of the room, and any pre-existing visual problems can worsen the picture.
But is there any way to protect your eyes and limit PC fatigue?
Yes, it is possible and today we will understand:
- The most important features of blue light glasses
- The best anti-blue light glasses on the market today
Let’s find out!
Anti-blue light glasses: Selection guide
Blue light: what is it and why does it hurt?
PC on the desk, tablet always in the bag, let’s not talk about the mobile phone… We are surrounded by LED screens and blue light. But what is it and what are the risks for our eyes?
Light is divided into a visible light spectrum, with wavelengths from 380 nm (nanometers) to 780 nm, and a non-visible light spectrum, which includes wavelengths preceding 380 nm (defined as ultraviolet) and those beyond i780 nm (defined infrared).
Blue light is defined as the non-visible component between 380 nm and 500 nm, also known as high energy visible light (HEV).
While UV rays are absorbed by the cornea and lens of adult individuals, blue light penetrates the lens, reaching the retina. In particular, the blue-violet wavelengths between 380 and 440 nm are considered one of the possible causes of photo-retinitis, i.e. the damage to the retina caused by high-energy incident light.
Headaches and migraines, eye fatigue, sleep disturbance, and retinal damage are the main consequences of blue light on the eyes! Credits: Theraspecs.com
Blue light is naturally present in a high percentage in daylight, while it is greatly reduced in the evening hours. Spending a day outdoors makes us absorb a significant amount of blue light, which has beneficial effects on our body.
It contributes to the production of vitamins, regulates our hormonal balance, and positively affects our mental and physical well-being. The human eye is used to being exposed to blue light during the day and reacts accordingly. The pupil tends to shrink to regulate the luminous flux but is unable to discriminate the nature of the wavelength.
The possible damage of blue light
If the subject pays close attention to what he is doing, such as working in front of a screen, the rhythmic closing of the eyelids becomes less frequent. This condition in which the eyes close less frequently causes dryness of the corneal surface, as well as possible damage to the lens and retina.
Today’s PC monitors or TV displays are the main suspects: the light emitted by these devices has a very high component of wavelengths in the blue spectrum. Mind you, the amount of HEV light these devices emit is only a small fraction of that emitted by the sun.
However, the time spent using these devices is very concerned about the possible effects they can have on the eyes. And despite the symptoms of CVS, which however present themselves with different levels of intensity and tend to disappear after a few hours from the end of the work, the blue light is harmful, even in the long term.
In the long run, blue light can lead to a reduction in the density of the macular pigment, which represents one of the risk factors for the onset of maculopathy.
7 tricks to limit blue light stress
Just as we all know how important it is to wear sunglasses for UV protection in bright sunlight, so we must pay attention to “invisible” blue light.
In fact, LED devices in xenon light, which as we know create the backlight in most monitors and televisions, contain a higher percentage of blue light than traditional light bulbs. The different spectral composition of the light leads to exposure to a particularly high quantity of blue light, which in some cases can create more or less pronounced annoyances.
We note that the blue light from such devices could not only create eye and vision problems but could also cause insomnia.
It is scientifically proven that blue light suppresses the production of melatonin, a hormone produced by the pineal gland that is essential for regulating sleep-wake cycles.
Therefore, even more so if we use a laptop before going to bed, or in any case a monitor we work on before going to bed, the anti-blue light glasses can be really useful, also to facilitate the subsequent sleep.
Before seeing blue light PC glasses, however, I find it useful to remember that there are some simple tricks to limit the risks associated with blue light exposure.
Among these we find:
- Adjust the brightness of the screen (the lower it is, the less it will stress the eyes).
- Change the background color from bright white to light gray.
- Do not place the screen towards the window, as the reflection is also harmful.
- Use blue light goggles to selectively shield the wavelengths of light.
- Increase the font size to make it easier to read.
- In the United States, they often recommend the 20-20-20 rule. Every 20 minutes look at something 20 feet (60cm) away for 20 seconds.
- If you still have dry eyes with the methods above, try any blue light software/apps (which add a reddish color to the display).
THAT SAID, THE PHYSICAL SHIELDING OF BLUE LIGHT GLASSES REMAINS OBJECTIVELY THE BEST “FILTER” TO PROTECT THE EYES.
We have seen that blue light radiation emitted by artificial light sources or screens can be irritating or cause eye fatigue for many people. Not surprisingly, pathologies related to the macula are on the rise, which can also cause serious vision problems.
A physical blue light filter can ensure clearer vision: the different wavelengths of visible light are refracted in slightly different ways by the cornea and the lens. It is for this reason that today special protective glasses for monitors are on the market, with lenses equipped with an anti-blue light filter.
What are the anti-blue light PC glasses for?
Anti-blue light PC glasses are born with the express purpose of protecting the eyes from the most harmful wavelengths emitted by LED/LCD displays.
It is a type of eyewear suitable for those who have problems reading in front of a computer, as well as those who feel fatigue in the eyes, which can be both dryness and difficulty focusing after being in front of the display.
These are protective glasses, which can also be worn by those who do not have vision problems, even simply for preventive purposes.
In practice, they offer an enhanced field of view for optimal vision up close and at intermediate distances, allowing a more relaxed and natural posture in front of the monitor.
Computer glasses differ from regular glasses or reading glasses because they are designed to optimize vision when viewing an electronic device (typically a PC monitor).
They are designed to reduce glare, filter out blue light, increase contrast, and reduce difficulty in focusing, making it easier to look at a screen for long periods.
There are characteristics of a neutral PC eyewear, i.e. without visual corrections applied, which are important in all cases. Let’s see the main ones:
Anti-reflection coating (AR)
This is a coating that eliminates light reflections from the front and back surfaces of the lenses, which could cause eye fatigue.
Some pc glasses have a generally yellow-tinted tint, designed to increase the contrast on the screen and filter out the blue light spectra so that the eye muscles relax. The lenses of some brands are darker, also suitable as sun lenses, with photochromic protection. As a degree of protection, yellow, together with transparent, remains the best.
Of course, glasses are often handled, they can fall out and you hit them. By fitting anti-scratch lenses, you will avoid having to make an additional expense if the lenses are damaged
Almost all anti-blue light lenses are also referred to as anti-flicker. Theoretically, they should be designed to make the viewing of the display more homogeneous, filtering any micro-flickering. In practice, personally, I have not found any particular scientific research on this aspect, so you have to trust the manufacturer as to whether it is useful or not. I don’t think it is fundamental.
An essential feature of good PC glasses is the comfort of the frame. Being devices to be worn for many hours a day, they must avoid straining the face. The materials used, therefore, play an important role!
So here’s everything you need to know about blue light and the choice of PC glasses.
NOW IS THE TIME TO SEE WHAT I THINK ARE THE TOP OF THE INDUSTRY!
Anti-blue light computer glasses: Ranking
Nowave is an Italian company specialized in the sector of eyewear with blue light filters.
Neutral glasses for PC anti-blue light are among the best ever, given the high ability to filter invisible light, confirmed by a decidedly lower dryness of the eyes after using them for a couple of hours.
These are specific anti-blue light PC glasses to avoid eye fatigue and damage during long sessions in front of the computer.
Nowave offers over 60 models of anti-blue light glasses and the frames are in acetate, titanium, and metal, therefore light and resistant.
The frames come from the East, while the lenses are very Italian, assembled in laboratories between Piedmont and Tuscany. Nowave Landfall glasses are a unisex model and neutral lenses are used, which offer good protection against blue light, all at very competitive prices, thanks to the direct producer-consumer distribution chain.
These are glasses for office PCs, or for home use in front of a TV or tablet, and they provide complete eye protection. These anti-blue light lenses are made of CR39, a latest-generation organic material, the most used by opticians in recent years.
CR39 is a much better material than polycarbonate, which is often used for this type of lens in cheaper models, as polycarbonate has poor results with regards to oleophobicity (a treatment that makes the lens or screen refractory to grease. deposited by fingerprints) and anti-scratch.
The lenses have a UV400 filter, which then filters out both UV-A and UV-B rays, and filters out most of the blue light at 430nm. They are equipped with HMC anti-reflective treatment and have a refractive index of 1.59, more than enough.
They are also anti-scratch and anti-glare, which also makes them perfect for night driving.
Equipped with CE, FDA, SGS, and Colts Laboratories (specialized in ophthalmic products) certifications, they are anti-flicker from monitors, so as to be particularly suitable for those who stay several hours in front of the PC.
The frame is in fact in TR90, a mix of nylon and carbon fiber that makes it light, flexible, and resistant, offering greater resistance to shocks and tractions.
These are made in Italy anti-blue light glasses that have become particularly appreciated because they are able to make the eyes feel more rested during work.
As soon as you put them on you don’t seem to notice much difference, but after wearing them for 4-5 hours, when they take them off, the monitor light will look really annoying.
These glasses convince both for the efficiency of protection and for the elegance of the frame. The materials chosen are of excellent quality, and the frame is hypoallergenic. From the first use, you can enjoy greater comfort and visual relaxation, preserving the well-being of the eye, without neglecting the aesthetic aspect.
Inside the package, in addition to the glasses, we find a hard case, a small cloth to clean the glasses, and a soft fabric case.
A quality made in Italy, with an excellent value for money and one of the absolute bestsellers among anti-blue light glasses for smart working, even among professionals. Not by chance.
Nowave – PC Landfall Resting Glasses – Price: 49.00 euro
Klim Technologies is a famous European brand known for the production of its popular anti-blue light glasses.
Klim Optics goggles guarantee true protection in front of screens. The lenses, made in Germany and in polycarbonate, filter 92% of blue light, a value much higher than the market average.
The frame is made of TR90, a very high-quality material: it is the lightest thermoplastic fabric available in the world and is used for high-quality frames. It is a flexible material, resistant to shocks and wears, it is not bent by heat and water repellent. Weighing only 20g, it’s practically like not wearing them.
They are born as top-quality gaming glasses, therefore for sessions of several hours in front of a monitor.
The Gaming Klim Optics glasses differ in a sporty style, have a thin metal structure near the lenses, and with temples covered with a rubberized material, pleasant to the touch. The two nose pads are in transparent rubber, with an interlocking fixing system that does not require screws.
The yellow tint of the lenses causes a slight color change, but it only takes a few minutes to become familiar with the new different shades of colors. The differences are highlighted in the absence of sunlight, with contrasting colors on the screen, which however improve the readability of the texts, as well as eliminate glare in case of excessive brightness of the screen.
The purpose of these glasses is to prevent any nuisance that blue light can create, and they are very suitable both for gamers who spend hours on this fun and for those who work long hours at the computer, perhaps in environments illuminated with artificial light.
Klim Technologies does not make prescription lenses, but the company makes the Clip-On variant, or the Klim OTG lenses, which can be attached to prescription glasses. The advice is not to overlap the graduated frame with this frame, to avoid problems of refraction and inclination.
Klim Optics lenses use an additional protective layer that further reduces light transmission in the blue frequencies. So the yellow lenses of this brand have a filtering capacity of 92%, the transparent ones of 86%.
Overall these are CE-certified PC glasses, with really good lenses. At first, the yellow color can be confusing, but after a very short time, you don’t notice it anymore. They come in a box with a hard case pouch and microfiber cloth.

➤ How do blue light glasses work?
The anti-blue light PC glasses are glasses with lenses treated by filters capable of effectively blocking the transmission of non-visible wavelengths, emitted by electronic devices. These glasses are often treated to prevent glare, UV rays, and glare, making the viewing experience less stressful for the eyes.
➤ What are the blue light glasses used for?
Blue light blocking glasses have lenses specially made to block or filter the blue light emitted by digital screens. The lenses help protect the eyes from glare, dryness, and stress. Melatonin levels also increase, which is thought to promote sleep in those people who use electronic devices just before bed.
➤ Do PC glasses really help?
There are several studies that certify how filters applied to anti-blue light lenses can reduce eye stress levels. One of the most important was carried out by the University of Houston in 2017 and showed that participants using anti-blue light lenses had an increase of about 58% in their nocturnal melatonin levels, thus promoting rest.
➤ What are the best anti-blue light glasses for PC or electronic devices?
Among the most recognized brands in Italy, we undoubtedly find Nowave, which offers anti-blue light and anti-UV glasses. Alternatively, Klim Optics, which designs and manufactures in Germany, is well known and appreciated.
➤ Do you recommend anti-blue light glasses?
I recommend anti-blue light computer glasses for sure if we spend more than 4 hours a day in front of the PC. I do not consider them essential for the use of the smartphone. Still, suppose we suffer from dryness or eyestrain after using an electronic device (as well as focusing problems after working on the PC). In that case, I can assure you that anti-blue light glasses they can make a real difference.
➤ Is there an adaptation period in the use of blue light glasses?
Yes, indeed, the first few times you wear computer glasses, you may not feel comfortable. Give the glasses an adaptation period of at least 1 week, using them when you are several hours in front of an electronic device (typically a PC). In this period of time, you should notice significant improvements related to less eye strain.
So here are the best anti-blue light glasses, both for PC and for any monitor.
As always, I remain available in the comments below.
Until next time!
