The Impact of Screens on Our Eyesight: Balancing the Digital Age
This article is about how worried some people around the glove are due to the constant screens that we are on every day and how they will affect our eyesight in the future.
In today's digital age, screens have become an integral part of our lives, from smartphones and tablets to laptops and televisions. While these devices provide numerous benefits and convenience, concerns have arisen regarding their potential impact on our eyesight. In this article, we delve into the effects screens can have on our eyes and explore ways to maintain healthy vision in the digital era.
The Strain of Extended Screen Time:
One of the primary concerns associated with screens is the strain they can put on our eyes. Staring at screens for prolonged periods can lead to digital eye strain, also known as computer vision syndrome. Symptoms include dry eyes, eye fatigue, blurred vision, headaches, and neck or shoulder pain. These issues arise due to factors like constant focusing, reduced blink rate, and exposure to blue light emitted by screens.
Blue Light and Sleep Disruptions:
Blue light, a high-energy visible light emitted by electronic devices, has drawn attention for its potential effects on sleep patterns and eye health. Research suggests that exposure to blue light before bedtime can suppress the production of melatonin, a hormone that regulates sleep. This disruption can lead to difficulty falling asleep and may affect the overall quality of sleep. While the long-term effects of blue light on eye health are still being studied, reducing exposure in the evening hours or using blue light filters may help alleviate potential risks.
Ergonomics and Viewing Distance:
Another aspect to consider is the ergonomics of screen usage. Poor posture and improper viewing distances can strain our eyes and lead to discomfort. Maintaining a proper distance from the screen, typically around 20-28 inches, and positioning it at eye level can help reduce eye strain. Additionally, taking regular breaks to rest the eyes and practicing good posture can contribute to overall eye comfort.
Screen Resolution and Clarity:
Advancements in display technology have led to higher screen resolutions, improved pixel densities, and enhanced colour reproduction. While these developments offer sharper and more detailed images, it's essential to strike a balance. Extremely high-resolution screens may encourage users to strain their eyes by focusing too closely or for extended periods. Adapting screen brightness, font sizes, and utilizing accessibility features can ensure a comfortable viewing experience.
Preventing Eye Strain and Maintaining Healthy Vision:
There are several strategies to minimize the impact of screens on our eyesight and maintain optimal vision:
Take Regular Breaks: Follow the 20-20-20 rule—every 20 minutes, look away from the screen at an object 20 feet away for 20 seconds. This helps relax the eye muscles and reduce eye fatigue.
Adjust Display Settings: Optimize screen brightness, contrast, and font size to suit your comfort and reduce eye strain. Utilize dark mode or night mode when available to reduce the amount of blue light emitted.
Blink Often: Remind yourself to blink regularly, as we tend to blink less frequently when staring at screens. Blinking helps moisturize the eyes and prevent dryness.
Maintain Proper Lighting: Ensure appropriate ambient lighting when using screens. Avoid glare by positioning screens away from direct light sources and minimizing reflections.
Consider Blue Light Filters: Explore the use of blue light filters or specialized glasses that block or reduce blue light. These can be particularly beneficial when using screens in the evening hours.
Visit an Eye Care Professional: Regular eye exams are crucial for monitoring eye health. A comprehensive eye examination can detect and address any potential issues early on.
In conclusion, as screens continue to dominate our daily lives, it is essential to be mindful of their potential impact on our eyesight. By adopting healthy habits, implementing ergonomically sound practices, and making use of available technologies and filters, we can strike a balance

The River That Carried My Questions
The river appeared where the forest ended, wide and patient, reflecting the pale light of early morning. Its surface moved slowly, as if reluctant to disturb the silence that rested over the valley. Imran stood on its bank, hands in his pockets, watching the water carry fragments of leaves and sky toward a destination no one could see. He had come here after many restless nights. In the city, time ran fast and loudly. Clocks ruled walls, phones ruled hands, and thoughts ruled sleep. Even when Imran closed his eyes, the world continued speaking inside him — about plans, regrets, deadlines, and choices he feared he had made too late. So he escaped, carrying nothing but questions. The path to the river wound through tall trees whose branches filtered sunlight into trembling patterns on the ground. Birds sang without urgency, as if music itself were a form of rest. Imran walked slowly, uncertain whether he sought answers or simply silence. When he reached the water, he sat on a smooth stone, letting the river speak first. At first, he heard only motion — the soft collision of currents, the whisper of water sliding over hidden rocks. But as minutes stretched into stillness, the sound became something deeper. Not noise, but rhythm. Not chaos, but order. He remembered stories his grandfather once told: that rivers were old teachers, that they carried memories of mountains, rain, and time itself. As a child, he had believed them without question. As an adult, he had forgotten how to believe at all. Imran picked up a small pebble and tossed it into the water. Circles spread outward, widening until they vanished. “Everything leaves a trace,” he murmured. His thoughts drifted back to the crossroads of his life — the job he accepted when his heart hesitated, the relationships he left unfinished, the dreams postponed in the name of safety. He had told himself these were sacrifices, but lately they felt more like abandonments. The river did not argue. Instead, it showed him something simple: every leaf, no matter how torn or twisted, kept moving. Some spun in small circles, trapped briefly by eddies, but eventually they found the main current again. Perhaps, he thought, confusion was not failure. Perhaps it was only a pause before direction. A fisherman appeared upstream, casting his line with slow precision. Each movement seemed deliberate, free from hurry. Imran watched him in quiet admiration. The man waited without impatience, as if time were an ally rather than an enemy. For the first time in weeks, Imran stopped checking his watch. He closed his eyes and listened — not to the river alone, but to himself. Beneath layers of worry, he found a gentler voice, one he had ignored for years. It spoke of curiosity, of unfinished ambitions, of a desire not for success, but for meaning. The river flowed on, unconcerned with human hesitation. When Imran opened his eyes, the light had changed. The sun now climbed higher, painting gold across the water’s surface. He realized that hours had passed unnoticed. Strangely, he did not feel he had lost time. He felt he had recovered it. Before leaving, he dipped his hand into the river. The water was cold, alive, undeniable. It reminded him that motion was natural, that stagnation was the true danger. As he stood, a thought settled gently in his mind: answers were not destinations. They were directions. He did not leave with a plan. He left with something better — clarity without pressure. Walking back through the forest, Imran noticed how light filtered through leaves, how insects traced invisible paths in air, how life continued patiently in every corner. He understood then that wisdom rarely arrived as thunder. More often, it came as water. When the city finally rose again before him, tall and restless, he did not feel the familiar tightening in his chest. The noise would return, yes. The responsibilities too. But now, somewhere beyond schedules and expectations, a river continued to flow — carrying not his answers, but his courage to keep asking. And that, he realized, was enough to begin again.
