Spending all day glued to a screen and ending up with burning eyes , headaches, and the feeling that everything is blurry is more common than you might think. Between the work computer, the mobile phone, the tablet, and even the TV, our eyes don't get a minute's rest, and that ends up taking its toll in the form of digital eye strain.
In recent years, solutions specifically designed to be easier on the eyes have emerged , and one of the most talked-about is the Bigme family of devices with color e-ink displays, including phones with e-ink screens , reading tablets, and monitors. These devices aim to combine the comfort of reading on paper with the advantages of modern technology for those who spend many hours in front of texts, graphics, or documents.
What is eye strain and why do screens stress us so much?
Digital eye strain, also known as computer vision syndrome, encompasses a range of discomforts that appear after prolonged use of computer screens, mobile phones, tablets, or televisions at close range. It is not a single condition, but rather a combination of visual, ocular, muscular, and even general symptoms that negatively impact quality of life and daily performance.
Among the most common visual symptoms are blurred or fluctuating vision , a sensation that letters are moving or doubling, photophobia (excessive sensitivity to light), or even double vision in some cases. These problems are triggered when we spend hours focusing our eyes on small text or interfaces full of detail.
At the purely ocular level, common symptoms include stinging, a gritty sensation, pronounced dryness, red eyes, a feeling of heaviness in the eyelids, or a slight internal pain as if the eye were "exhausted." Many people also experience headaches, nausea, some unsteadiness or vertigo, as well as stiffness in the neck, shoulders, back, arms, and wrists due to awkward postures in front of the screen.
The root of the problem is usually a mixture of visual, environmental and general health factors : poorly corrected refractive errors (myopia, hyperopia, astigmatism), accommodation and convergence problems, poor lighting, screen reflections, excessive brightness, poor ergonomics, sustained stress and, of course, too many consecutive hours without reasonable breaks.
All of this is exacerbated because, when looking at screens, we blink much less : it has been shown that blinking frequency can drop from about 18 times per minute to just 3 or 4 when we are very focused on the computer. By opening our eyelids more and blinking less, the surface of the eye dries out, the tear film breaks down prematurely, and the familiar gritty, itchy, or burning sensation appears.
How traditional screens work and why they cause so much fatigue
Classic computer screens (back in the day, cathode ray tubes) and modern LCD and OLED displays share something important: they both rely on a light source projected directly into your eyes. In older monitors, the electron beam traveled across the screen, striking light-emitting diodes; in modern LCDs and OLEDs, it's the backlight or the diodes themselves that shine continuously in front of you.
This constant emission of artificial light forces the visual system to make a sustained effort to maintain focus at close range for many hours. The ciliary muscle, responsible for adjusting focus, remains contracted, which can cause accommodative spasms, temporary false myopia, difficulty focusing at a distance at the end of the day, and pain in the frontal area of ​​the head.
Furthermore, these screens emit a significant amount of blue light , a component of the spectrum that, although part of visible light, has been associated with oxidative stress in retinal cells and disruption of circadian rhythms. This means that intense exposure at night can interfere with melatonin production and worsen sleep quality.
The combination of bright light, flickering images, strong contrast, and glare leads to cumulative eye strain. In low ambient light or poorly controlled glare, the eye has to constantly adapt, further straining the visual system and amplifying discomfort.
Comparative studies indicate that LCD and OLED screens can increase eye strain several times more than reading on physical paper or e-ink devices. After a certain number of hours of use, symptoms become almost inevitable if preventive measures are not taken.
The alternative: why e-ink is much less tiring on the eyes
Electronic ink (E-Ink) technology was designed precisely to mimic paper . Instead of emitting light, these panels work with microparticles of ink that rearrange themselves when they receive an electrical charge, forming text and images that remain stable until the next page turn.
By reflecting ambient light instead of generating it , e-ink devices don't project a direct beam of light onto the retina. Your eyes see the surface almost as if it were a printed sheet of paper, which is infinitely more comfortable for long sessions of reading, studying, or working with extensive documents.
Another major advantage is the absence of image flicker . While a conventional monitor refreshes dozens of times per second, generating a flicker that the brain has to process (even if you're not consciously aware of it), with e-ink the image remains static until you turn the page or refresh the content. This translates into less visual processing effort and a noticeable reduction in eye strain.
The matte finish of most e-ink displays also helps a lot , minimizing reflections and glare. Reading near a window or outdoors is no longer a chore because the ambient light doesn't bounce around aggressively, promoting a relaxed viewing posture and more natural eye movement.
In terms of sleep, the advantage is even clearer : because they don't rely on bright backlighting or large spikes in blue light, e-ink readers and monitors can be used at night without significantly disrupting circadian rhythms. Many users report that they can read until shortly before bed without it affecting their ability to fall asleep.
Bigme and the revolution of color electronic ink in mobile phones and tablets
For years, integrating e-ink into a mobile phone has been a significant technical challenge . These screens have lower refresh rates (often around 30 Hz), making them unsuitable for videos, games, or fast-paced animations. Therefore, early attempts, such as the famous dual-screen YotaPhone, remained niche products.
Bigme's strategy is to combine the best of both worlds in a single device : on one hand, a conventional LCD screen for multimedia content and tasks requiring fluidity, and on the other, an electronic ink screen (in many models, in color) for reading, writing, quiet browsing, and anything involving many hours of text.
In some of its latest developments, Bigme uses Kaleido technology , a color electronic ink system based on physical filters over a monochrome e-ink panel. This achieves three primary colors and a palette sufficient for graphics, diagrams, or illustrations, without adding extra layers of backlighting that increase light emission and, consequently, eye strain.
The brand itself has presented ideas like dual-screen smartphones on specialized forums such as Reddit, seeking feedback from user communities that prioritize visual comfort and battery life over the visual appeal of an AMOLED panel. This is an audience that values ​​being able to read, take notes, or consult documents for hours without their eyes getting strained.
Bigme B751C: a clear example of how to reduce eye strain
Within Bigme's catalog, the B751C model is one of the best examples of this approach . It's a 7-inch device with Kaleido color e-ink, designed as a digital notepad and advanced reader for those who read a lot of digital content.
By using reflective e-ink instead of a backlit screen , the B751C virtually eliminates the main cause of eye strain associated with traditional tablets: the light shining directly from the panel. The experience is much closer to reading a physical book, but with digital annotations, access to libraries and documents, and the entire ecosystem of compatible apps.
The B751C's three-color Kaleido display shows color graphics and diagrams without requiring a bright light source behind it. Physical filters separate the colors, but the principle remains the same as e-ink: the particles are rearranged and stabilized, and the eye perceives a surface illuminated by ambient light.
Another strong point is the absence of perceptible flicker . The image remains stable while you read, providing a real break for your eyes. Many users comment that, after four or five hours of continuous reading on this type of device, they feel as comfortable as when they started, something unthinkable with a standard LCD tablet.
The B751C's matte finish and low screen reflectivity significantly reduce glare , both indoors in changing light and near windows or outdoors. For those who study or work in naturally lit spaces, this translates into a more relaxed posture, without constantly moving the device to avoid reflections.
Bigme monitors and smartphones: real experiences with eye strain
Beyond the technical specifications, user experiences with Bigme e-ink monitors provide a clear picture of their impact on eye strain. Applications like Instapaper on e-ink displays allow users to manage articles and long reading sessions without straining their eyes, and there are testimonials from people who, after years of suffering extreme eye fatigue with LCD screens, have found considerable relief with these monitors.
One user recounts that, after reaching a point of no longer being able to bear the eye strain , he decided to buy his first e-ink device: a Kindle reader and a Bigme 25,1-inch monitor. After a month of getting used to it, he noticed a significant improvement in his eye fatigue and that he could work longer without the usual pain.
In his case, he comments that for pure text he still finds the Kindle's contrast somewhat superior , and that if other brands' black and white monitors offered the same quality as the reader, he would prefer that monochrome option over a color monitor, precisely because the text looks darker and more defined.
He also mentions an important detail: the bright screen and reflections can still be a problem , even on an e-ink monitor, if the lighting isn't properly adjusted. He even used a dedicated reading lamp and positioned himself facing a window with the sun at his back to improve comfort. In the end, he discovered that working in direct natural light at the right distance was more comfortable than relying on harsh artificial lighting.
Over time, he installed an anti-glare screen protector and noticed a further reduction in eye strain, to the point of recommending this type of accessory to anyone wanting to maximize the visual comfort of an e-ink monitor. However, he also mentions that three permanent white lines appeared on the screen and that the physical power button stopped working, forcing him to use the remote control; he attributes this likely to bad luck with the unit itself, rather than a general defect in the brand.
Bigme screens versus conventional screens: differences in eye strain
When comparing e-ink devices like the Bigme B751C or e-ink monitors with traditional LCD and OLED screens, the differences in terms of eye strain are especially noticeable during long sessions. Studies indicate that eye strain with e-ink is quite similar to that of reading on paper, while emissive screens can multiply the feeling of fatigue several times over after a few hours.
The contrast of the text against the light background in Bigme helps the eye focus effortlessly , preventing the typical gesture of squinting to see better or constantly moving the screen closer and further away. This natural clarity allows the ciliary muscle to work more easily.
Furthermore, the absence of direct blue light from these protective panels minimizes the impact on sleep . Those who use the Bigme to read at night tend to experience fewer problems falling asleep than when using a backlit tablet, as it doesn't disrupt the circadian rhythm or melatonin production as much.
For people with migraines triggered by screens, light sensitivity, or dry eyes , Bigme devices are particularly interesting. By eliminating screen flicker and drastically reducing direct light, they decrease many of the stimuli that typically trigger attacks or worsen symptoms.
That's why more and more professionals who spend many hours reading or reviewing technical documents (engineers, doctors, lawyers, researchers, university students) are incorporating a Bigme e-ink into their routine: they use it for everything that involves long texts and leave conventional screens for specific tasks that require fluid video or very dynamic graphics.
Configuration and ergonomics: how to get the most out of a Bigme to take care of your eyes
Although a Bigme device already reduces many of the causes of eye strain , it's important to adjust it properly and pay attention to ergonomics to maximize its benefits. It's not just about the screen technology: posture, distance, and ambient lighting also play a role.
One of the first key adjustments is the font size . It should be set so that you can read at your usual distance (around 40-50 cm if handheld or 50-70 cm if using a desktop monitor or tablet) without straining your eyes or having to hold the device too close to your face. Fonts that are too small require extra muscle effort; fonts that are too large can decrease reading efficiency.
Ambient lighting should be uniform and preferably indirect . Even though the Bigme screen doesn't emit harsh light, reading in the dark with a single, very bright light shining on the device isn't a good idea. The most comfortable environment is usually a well-lit room with diffused light that avoids harsh shadows and reflections on the screen.
In terms of ergonomics, it's best to position the device so that your gaze falls slightly downwards , keeping the top edge of the screen slightly below eye level and at a distance of 50 to 70 cm if it's a monitor. This reduces eye strain (by not opening the eyelids as wide) and improves neck and back posture.
Don't forget visual breaks . Although BigMe is much less tiring, the visual system still appreciates rest. Applying the 20-20-20 rule (every 20 minutes, look at something more than 6 meters away for 20 seconds) helps relax the eye muscles and reduces the risk of spasms and pseudomyopia.
Other medical and lifestyle strategies to combat eye strain
Bigme's e-ink technology is a powerful piece of the puzzle , but it doesn't replace a comprehensive eye exam or correct underlying problems on its own. Anyone experiencing persistent discomfort should consult an ophthalmologist to rule out poorly corrected refractive errors, accommodation disorders, severe dry eye, or other conditions.
Many office workers have uncorrected mild refractive errors or outdated glasses, which increases eye strain when using screens. Properly adjusting prescriptions, checking contact lens fit, and adequately treating dry eyes with artificial tears or moisturizing eye drops can make a huge difference.
In cases of evaporative dry eye associated with Meibomian gland dysfunction , specific treatments such as intense pulsed light (IPL laser) are gaining prominence. This system helps improve the quality of the tear film, reduce inflammation along the eyelid margin, and decrease the sensation of dryness and burning, resulting in greater comfort when using any screen, including e-ink displays.
The recommended frequency for these IPL treatments is usually maintenance every six months for people with high visual demands and chronic symptoms, always under the supervision of a specialist. It is a quick, minimally invasive technique with a good safety profile, which fits well into a comprehensive approach to eye strain.
Other general health factors should also be considered, such as hormonal changes (for example, menopause), autoimmune diseases, and certain medications (psychotropic drugs, antihistamines, antihypertensives, acne medications, and some eye drops) that can affect the tear film and predispose individuals to dry eye and eye strain. In these cases, coordinating treatment strategies with a doctor is essential.
Nutrition, antioxidants and protection of the retina against blue light
In addition to screen changes and ergonomic measures, internal eye protection is also important . Prolonged exposure to blue light from emitting devices generates free radicals and oxidative stress in retinal cells, which in the long term could contribute to premature eye aging.
Specific supplements like MACAMI RETICARE have been formulated precisely with this idea : to support the visual system from within in people who spend many hours in front of screens. They contain antioxidants and carotenoids from microalgae and plant extracts, such as lutein, zeaxanthin, astaxanthin, and black tomato extract.
These compounds are naturally concentrated in the macula and other ocular structures , where they help filter some blue light and neutralize free radicals generated by light exposure. According to data collected in their clinical dossier, certain combinations, such as lutein-zeaxanthin-black tomato, can reduce the production of blue light-induced free radicals in human retinal epithelial cells by up to 90% in vitro.
The idea behind these types of supplements is not to replace healthier screens like those from Bigme , but rather to complement them in a world where we are still surrounded by mobile phones, laptops, and televisions. A smart strategy typically includes choosing less harmful devices, maintaining good viewing habits, and ensuring adequate nutritional support.
In this context, Bigme and solutions like MACAMI RETICARE are part of a comprehensive approach for those who live literally glued to screens: hardware changes, environmental adjustments, medical support when needed, and a long-term view of eye health.
It is becoming increasingly clear that caring for your eyes involves combining gentler technology like Bigme's e-ink , well-designed ergonomics, visual breaks, specific treatments for dry eyes or other problems, and, if necessary, added antioxidant protection; with all this, it is possible to continue enjoying the digital world and work long hours without your eyes becoming the main victim of the day.
