the subtle change on your screen that your eyes will appreciate after eight hours of Excel

If you work or study for many hours every day in front of the PC screen, It is very likely that you will end up with tired eyes: reading a lot of text, watching videos, going from one Excel to another (and then to another, and another), writing, editing images or videos and a very long etcetera of tasks sustained over time will almost certainly cause you to have eye fatigue and a tiredness in your eyes that is as uncomfortable as it is unhealthy. If you have no choice but to be in front of the monitor for a good handful of hours each day (something quite common in many cases, in these times), you can always do everything possible on your part to minimize it and even remedy it: Get up every now and then, don’t stare too long at a time and look at distant objects, stand at a distance that prevents you from straining your eyes too much, and more similar tricks. And added to all this, I am going to give you an idea that perhaps you had not considered and that is not going to solve your life, but it will make you gain visual comfort (and I say this from experience): using a monitor with a high refresh rate. Even if you don’t play. Because having more than 60 Hz (120 Hz, 144 Hz and even more) is an excellent idea outside of the field of video games. And (spoiler) nowadays, the price difference between some monitors and others is so small, that I can tell you that it is very worth it that little extra investment. What is refresh rate (and what does it affect) Okay, on paper, purely speaking of specs, 120Hz is better than 60Hz. And 144 Hzbetter than 120 Hz. That has become clear to us. But exactly what are we talking about? We are talking about hertz, which in short determine the number of frames per second that the screen in question is capable of displaying. In other words: the number of still images that appear, one after another, in one second of time. The greater the quantity, the more fluid the image, which can be a video game, a video or the apps we use in our daily lives. The latter, just what we are looking for. In practice, having more than 60 Hz and therefore a higher refresh rate translates into fluidity. Fluidity in everything: transitions, application effects, window and cursor movements, scroll much softer and, ultimately, everything that generates movement on the screen. Something that may seem minor, but in the long run, and after spending hours in front of the monitor, it is noticeable. A one-way road. At this point, we must take into account the ‘price factor’. Because long ago, going above that base 60 Hz from which monitors start was expensive. However now, with refresh rates that even exceed 360 Hzwe find 144 Hz (or 120 Hz, or 165 Hz and even more) options at great prices. Which means that for a fairly contained investment you can make a huge leap in quality. The good and the bad, face to face Although the theory is simple, the differences between one type of monitor and another can be confusing if you are not familiar with it. Then, This table as a summary will clarify it a lot for you.. 60Hz 144Hz THE GOOD 🟢 Cheaper (and you can allocate more budget to other specifications: resolution, size…) Great fluidity in images and a standard to play today THE BAD 🔴 They offer less fluidity and are somewhat outdated in 2026, as they can make the jump to 144 Hz or more at similar prices Slightly more expensive than 60 Hz and, in general, more striking gaming design IDEAL FOR Users who do not feel visual fatigue, who feel comfortable at 60 Hz and do not want to spend more Gamers (or non-gamers) who want to take a leap in visual comfort Which one may interest you more: we do the math As we have already mentioned, price is not a determining factor today when deciding between a 60 Hz monitor and another with 144 Hz or more. Even so, if a 60 Hz one is enough for you, you can dedicate that extra investment in other aspects of the screens, such as the resolution, the diagonal or the format. Actual use: 60 Hz is enough for you and you prefer to spend what 144 Hz would cost you on a ultrawidebecause you need more horizontal space on the screen. What experience you get: similar to what you have been obtaining with previous 60 Hz monitors, but you gain in those other characteristics that are important to you (more diagonal, different format, more resolution…). If, on the other hand, you notice that after finishing the work day your eyes are very tired and it seems that applications, transitions and other movements are not as fluid as you would like, then going from 60 Hz to 144 Hz or more is an excellent decision. Spending little more than you would with a 60 Hz monitor, you double (and even more) its refresh rate and the view thanks you. Actual use: It bothers you that the animations of the operating system, the scroll or the passing of the cursor across the screen goes in fits and starts and you decide to go above 60 Hz. What experience you get: From the first second, you see that everything runs more smoothly and is more comfortable for the eyes. Where before there were almost imperceptible but existing cuts, now everything is going smoothly. It even looks like you’ve upgraded to a better PC! In summary: 👉 Choose 60 Hz if: You don’t notice visual fatigue because you don’t spend too many hours in front of the screen, you don’t want to spend more and you also don’t play games or plan to do so in the short term. … Read more

We have been blaming mobile phones for myopia for years. Now we have a much more subtle suspect: lack of light

It is quite a grandmother’s and mother’s phrase to hear that spending a long time in front of a screen or being very close to a book can cause us to develop a disease in the eyes like the myopia. However, science has long suspected that “close work” alone does not explain why myopia has become a global pandemic. The new. Now a revealing study has proposed a physiological mechanism that fits all the pieces of the puzzle together, placing the blame not only on what we look at, but on the amount of light that reaches the back of our eye while we do so. And the investigation is quite justified, since the data is scary. In Spain, 19% of children between 5 and 7 years old are already myopicand projections estimate that by 2050 half of the world’s population will need glasses. To stop this, we need to understand exactly the mechanism that produces myopia, and a team from New York has found the key. The famine of light. The work, recently published in the prestigious magazine Cell Reports by researchers, points to a fascinating concept in this case: the light deprivation hypothesis. Until now we knew that focusing on nearby objects is closely linked to the development of myopia. But what this study has measured with empirical precision is how the myopic eye reacts to the healthy eye during this process. What they have seen. The main finding is that myopes suffer from excessive accommodative pupillary constrictionthat is, when you look closely, the pupil becomes much smaller than normal. If we add to this that close-up work is usually done indoors where lighting rarely exceeds 500 lux, compared to 10,000 lux outdoors, the result is a lethal cocktail for the eye: the combination of dim light and a maximally contracted pupil causes the retina to “starve” due to lack of light. The short circuit. Here the question that logically must be asked is: Why does this lack of light cause the eye to grow abnormally, causing myopia? This is where the purest neuroscience comes in, since our retina processes the image through two main channels: the ON path that is activated with increases in light, and the OFF path, which reacts to shadows. In previous work from 2024, this same team had already shown that in myopic patients the ON pathways have serious deficits, since they are less sensitive and slower. Now the new hypothesis postulates a vicious circle in which, when reading or looking at a cell phone indoors, the pupil closes too much. And this is a problem, since chronic lack of light further weakens the retinal ON pathway, and this imbalance sends erroneous signals that ultimately promote elongation of the eyeball. The treatments. This proposal not only stands out for explaining the biological mechanism of myopia, but also unifies at once why the treatments that ophthalmologists They have been applying it empirically for years. One of the examples is spending time outdoors, but not because it cures, but because the sunlight is so intense that it more than compensates for having a small pupil, keeping the ON pathway stimulated and slowing the progression of myopia. Another example is the use of atropine drops in children to stop myopia thanks to the dilation of the pupil so that more light enters the retina. The same goes for multifocal lenses that are used to reduce accommodation effort, since the pupil does not need to constrict as excessively. It is not definitive. As is almost always the case in science, this work does not demonstrate a direct coincidence yet, but rather offers us an incredibly solid and plausible physiological mechanism supported by very robust data on the behavior of our pupil and neural pathways. But there is still a way to go with new long-term studies to confirm the hypothesis 100%. While we wait for those results, the practical conclusion seems clearer than ever: the problem is not just the tablet or the book. The problem is doing it in the dark, so if you are going to strain your eyes up close, make sure you turn on a good lamp and, above all, don’t forget to go out into the sun.

It is a subtle shortcut to self -destruct according to psychology

“Never enter dispute with a fool, will drag you at your level and win you from experience,” a phrase attributed to the American writer Mark Twain. In this way, this type of maxim has reinforced the idea that avoiding conflict is a sample of wisdom or self -control. Popular culture, family environments and even some educational speeches have promoted silence as a way of preserving harmony. However, what happens when to shut up ceases to be a specific strategy and becomes a life standard? Is it really mature who avoids the confrontation at all costs, or simply fears the consequences of raising the voice? When shutting up becomes a habit. “Shutting up does not make one mature, but submissive,” writes the psychologist Luis Miguel Real Kotbani In a column published in Ethic. There he states that the silence sustained in uncomfortable situations, far from guaranteeing harmony, can end up becoming a silent conviction: a strategy that begins with the intention of preserving peace, but ends up nullifying voice and personal needs. This pattern is not limited to relationships. It is replicated in work, family and friendship environments, where many people choose not to express their disagreement to avoid tensions. “Every time you choose silence so as not to bother, you give them the message that your needs are worth less,” says Real, who links this practice with a progressive loss of self -esteem and agency. Deeper roots. From the clinical look, the habit of shutting up has multiple causes. Psychologist Mario Arzuza, cited in the chroniclerHe points out that many people who avoid the conflict have been educated in environments that prioritize tranquility over authenticity. “This behavior is usually linked to low self -esteem, need for approval or fear of rejection,” he explains. Other individuals have grown in contexts where the conflict was associated with danger: screams, violence, abandonment. In these cases, any confrontation, however minimal, can activate disproportionate emotional responses. According to the chroniclerthis dynamic is frequent in people with deep insecurities or history of emotional trauma. Psychopedagogue Sylvie Pérez, In an article from the Oberta de Catalunya (UOC) University (UOC)warns that the avoidance of the conflict is usually learned in childhood, when adults use silence as a form of punishment. This practice, known as “Ice Law”, generates in children feelings of guilt, rejection and misunderstanding, and can install patterns of emotional submission that are dragged to adulthood. The drift of silence. In his article the real psychologist Also alert about the cumulative impact of silence: “Today you shut up in a small discussion, tomorrow swallows something bigger, and in the end you have been in a relationship where the only way of not generating conflicts has been to disappear yourself.” This prolonged silence affects not only the relationship with others, but also with oneself: the person ceases to wonder what he wants or needs, and lives automatically, disconnected from his own voice. In addition, systematic silence can erode links. Sheila Heen, conflict management specialist of the Harvard negotiation project, holds in Harvard Gazette than avoiding difficult conversations at all costs weakens relationships. “It’s not about discussing all the time, but either of never talking about what hurts. That chronic avoidance destroys the quality of the link,” he says. The limit: Does this relate to the ice law? Silence as a strategy to avoid conflicts should not be confused with the ice law. While the first is a form of self -preservation (although harmful), the ice law implies an intentional behavior, which seeks to punish the other with silence. This is the New York Timesin an article where this practice is described as an “emotionally punitive form” that can produce both damage and direct aggression. “Answering silently is a punishment, you recognize it or not,” says psychiatrist Gail Saltz, cited in the same medium. The damage is tangible: research by Professor Kipling Williams (University of Purdue) shows that being ignored in the brain the same areas that are activated before physical pain. In family contexts, As the UOC points outthe ice of ice applied to children can have lasting effects on their self -esteem and emotional development. In that sense, although shutting up for fear does not equal to manipulate with silence, both practices share a common substrate: the lack of genuine dialogue as a means to solve tensions. The difference lies in the objective and the direction of the damage: in one case, who is silent; in the other, who is withdrawn the word. Breaking with years of silences is not easy. But possible. The key is to develop assertive communication skills, which allow to express what one thinks and feels without aggression, but also without renunciation. The psychologist, Luis Miguel Real, proposes to start with the small: say in a conversation, say what you want to do in a plan, mark a subtle limit. From psychology, it is also recommended to work the tolerance to discomfort, practice emotional regulation exercises and, in more entrenched cases, resort to professional help. From the chronicler They suggest Identify irrational thoughts that feed the fear of conflict, while Harvard Gazette They underline The importance of reflective silences (not punitive), as a tool to think before speaking and not to evade the important. Avoiding conflict is not always wise. Sometimes it is a form of surrender. And the price of that surrender can be the loss of one’s voice. As real summarize: “Talking, putting limits, saying what you think, is not to create problems: it is respecting you. And who cannot deal with your voice, may not deserve your presence.” Shutting up does not guarantee peace. Just postpone the conflict or internalize it. The real challenge is not to avoid it, but to learn to face it without fear, with honesty and respect. Because, in the end, what is not said, does not disappear: it rots inside.

subtle improvements that refine a compact mobile that already shone on its own

Sometimes I wonder to what extent we are willing to sacrifice the comfort for having The most powerful mobile. It seems that the market has convinced us that “bigger” always means “better”, but not all manufacturers think the same. As we said a while ago: “small” mobiles are not finished. Xiaomi is part of this. This Sunday, in the Mobile World Congress, the Chinese brand has revealed its new Xiaomi 15 family, with the Xiaomi 15 Ultra at the top and the Xiaomi 15 as a more contained alternative but equally promising. Although they have just been presented and are already available in Spain, I have had the opportunity to try the most “compact.” Xiaomi 15 Technical Card Xiaomi 15 dimensions and weight 152.3 x 71.2 x 8.08 mm 191 grams screen OLED LTPO of 6.36 inches Resolution 2,670 x 1,200 pixels Refresco rate: 1-120 Hz Tactile sampling rate: 240 Hz Pico shine: 3,200 nits Pro HDR, Dolby Vision, HDR10+, HDR10, HLG Xiaomi Shield Glass processor Snapdragon 8 Elite Adreno GPU RAM 12 GB LPDDR5X Internal storage 256/512 GB UFS 4.0 rear camera Angular 50 MP, OIS, F/1.6 GREAT ANGULAR 50 MP, OIS, F/2.2, 115º FOV Telefoto 50 MP, F/2.0 Front camera 32 MP F/2.0 battery 5,240 mAh 90W fast charge 50W wireless fast charge Operating system Hyperos 2 connectivity 5G SA/NSA Dual Nanosim Wifi 7 NFC Bluetooth 5.4 Infrared port others Ultrasonic fingerprint reader on screen IP68 resistance Stereo speakers 4x microphones price From 999 euros Xiaomi 15 – 12+512GB Smartphone, Leica Summilux optical lens, Snapdragon 8 Elite, 6.36 “” 120 Hz, Hz, 90W Hypercharge, 90W Hyperchar, charger not included, black (ES version) * Some price may have changed from the last review Small adjustments that lead a mobile already outstanding one step further The first impression I had when I saw the Xiaomi 15 was that this year the company had not risked too much with the design. But, after thinking about it, I realized that it doesn’t have to be something negative. Many brands are committed to evolving their generation product after generation instead of reinventing it. Apple does it with the iPhoneFor example. With that idea in mind, I decided to approach the device with more attention. Was it a discreet but well thought out or simply logical continuity? Sometimes, the most interesting details are not noticed at first glance, but jump when we see calmly. I also wanted to answer the big question: what has really changed on this mobile? The feeling of being before a Premium product It is perceived as soon as you have it in your hand. The aluminum frame of “aerospace grade”, the rounded edges, its 8.08 mm thick and a weight of 191 grams contribute to a careful ergonomics. Xiaomi also ensures that he has distributed the weight in a balanced way to enhance this feeling. Chamber modules in detail: Xiaomi 14 (left) in front of Xiaomi 15 (right) In the back of the device we find a family design, without obvious changes with respect to the previous generation. The photographic module is still located in the upper left corner, housing three sensors. The novelty is in the flash, which leaves this module to be directly on the rear cover, inside a stylized elongated capsule. The back of the Xiaomi 15 white Once again, Xiaomi is committed to collaboration with Leica, the legendary photographic firm that has long reinforces the visual section of its devices. As for hardware, There are no great revolutions: Again, three 50 MP sensors each. However, the AI ​​offers better both in the image processing section and in the zoom. The sides of a black Xiaomi 15 If we stop in the details, a change that is obvious is the finish of the rear. While the Xiaomi 14 opted for a brilliant and striking glass, the new Xiaomi 15 adopts a frosted glass With a more discreet matte finish. In addition, the subtle textured bezel surrounded by the camera module has disappeared in this update. The Xiaomi 15 has rounded edges, a detail that improves ergonomics The matt rear and the aerospace aluminum edges not only provide elegance, but also a key advantage: they do not catch traces easily. For those who enjoy an always impeccable mobile, this finish is a success. Although at certain angles they can be marked, the difference with other models is remarkable. There are much more prone options to get dirty. The Xiaomi 15 come in three colors, black, green and white Xiaomi maintains the same color palette: black, white and green. However, The tones are now softerwhich slightly changes the perception of design. Personally, the green finish is the one that highlights in this model, while white, with its contrast marked in front of the black photographic module, I found the most attractive. On the front we find, once again, with a 6.36 -inch OLED screen, resolution of 2,670 x 1,200 pixels and a refreshment rate of up to 120 Hz. The maximum brightness has risen from 3,000 to 3,200 nits, an interesting increase, although in my fast tests under direct sunlight still does not seem sufficient. We will check it in the Review complete phone. The front of a white Xiaomi 15 News are also in the least visible details. Specifically those that inhabit under the screen. Xiaomi has left the optical footprint sensor behind and makes the leap to a ultrasonic sensorwhich promises a faster and more reliable unlock. In addition, it should work even with wet hands. All this without compromising the safety of the device. A white Xiaomi 15 The mobile also wins in autonomy. The battery rises from 4,610 mAh to 5,240 mAh without the weight. Quick cable charging remains at 90 W and wireless in 50 W. Of course, there is a negative point: the charger is not included in the box, which would lead us to make an additional investment to make the most of it. Since the end of last year … Read more
