In this age of information, our eyes are dealing with electronic screens almost all the time. From the moment we press our phone's alarm for the first time in the morning, to finish our last job at the computer at night, to stay up late at night to catch up on dramas or socialize**, our eyes are being tested like never before. Have you ever experienced dry eyes, blurred vision, or even headaches? These can be signs of overuse of the eyes.
In the face of such a situation, how can we effectively protect our "windows"? It's not just a matter of health, it's a matter of quality of life.
In this digital age, our eyes are under pressure like never before. When we stare at a screen for work or play for long periods of time, our eyes need to constantly adjust focus, combat the blue light of the screen, and process flickering images. The combination of these factors leads to what is known as digital eye strain (DES), which in turn affects our vision health.
Excessive screen time
When we overuse electronic devices, the eyes need to be constantly focused on objects at close range, resulting in overaccommodation (the ability of the eye to adjust focus), which can cause eye strain and discomfort. It's not just an adult problemChildren and young people are also facing this challenge, especially as distance education and online entertainment become more commonplace.
Blue light exposure
The blue light emitted by electronic screens can penetrate the eyeball directly to the retina, and prolonged exposure may damage the photoreceptors of the eye, resulting in vision loss. Blue light is also considered one of the main culprits affecting sleep quality because it interferes with the biological clock in our body, making it more difficult to fall asleep.
Incorrect sitting posture and lighting
When working in front of a computer or phone, incorrect sitting posture and inappropriate lighting conditions can also aggravate eye strain. Inappropriate screen placement and too much or too little light can force the eyes to work too hard to adapt to the environment, which can increase the strain on the eyes.
Countermeasures and suggestions
Once we understand what causes eye overload, we can alleviate this problem by adjusting our daily habits and environment. For example, take the 20-20-20 rule (every 20 minutes, look at an object 20 feet away for 20 seconds).Using anti-blue light glasses, optimizing sitting and lighting at workstations, and engaging in regular eye exercises are all effective strategies to protect your eye health.
Protecting your eyes in the digital age requires not only awareness, but also a series of concrete and feasible measures. Here are some effective prevention and protection measures to help relieve eye strain and reduce the risk of vision damage.
Adjust your screen habits
20-20-20 rule: Every 20 minutes, shift your gaze from the screen to at least 20 feet (about 6 meters) away and gaze for 20 seconds. This helps to reduce the focus pressure on the eyes.
Screen brightness adjustment:Adjust the brightness of the screen to match the surrounding environment, avoid the screen being too bright or too dark, and reduce the adjustment burden on the eyes.
Use night mode: Most devices offer a night mode option that reduces exposure to blue light, helping to protect the retina and improve sleep quality.
Optimize your work and reading environment
Correct sitting posture: Keep the screen at eye level or slightly lower, about 50 to 70 cm away from your eyes. This helps to reduce pressure on the eyes and neck.
Adequate lighting: Make sure your work or reading environment has plenty of natural light or soft artificial lightAvoid strong direct light or reflections to reduce eye strain.
Regular eye exercises
Eye exercises: Regular eye exercises, such as eye movements, blinking, etc., can help relieve tension and fatigue in the eye muscles.
Relaxation from afar: Taking advantage of your break time to look out the window at distant objects helps your eyes relax and adjust.
Healthy lifestyle
Eat a balanced diet: Foods rich in vitamins A, C and E, as well as omega-3 fatty acids, such as green leafy vegetables and fish, are important for maintaining eye health.
Get enough sleep: Getting enough sleep helps your eyes repair and recover on their own.
Regular eye exams: Even if you don't feel uncomfortable, you should have an annual eye exam to detect and treat vision problems early.
To relieve eye fatigue and protect eyesight, regular eye exercises are a simple and effective way to do it. Here are several eye exercises that can be done at any time and placeIt is designed to reduce eye strain, improve blood circulation in the eye area, and enhance the ability of eye muscles to adjust.
Eye movement exercises
Look straight ahead, try not to move your head, look up with your eyes, and then slowly look down.
Look left and right: see the limit to the left, and then see the limit to the right.
Circular motion: The eyes turn clockwise and then counterclockwise.
Each movement is repeated 5-10 times, which helps to relax the eye muscles and reduce tension in the eyes.
Focus shift exercises
Choose a nearby target (such as a pen in your hand) and then find a distant target (the tree outside the window).
Alternate gaze:Staring at a nearby target for a few seconds, then quickly switching gaze to a distant target, continuing for a few more seconds, repeatedly.
This exercise can help improve the eye's ability to focus and reduce visual fatigue caused by prolonged screen viewing.
Blink exercises
Blink deeply a few times, then keep your eyes closed for a few seconds.
Gently blink frequently for a minute.
Blinking can promote tear production, lubricate the eyeballs, and reduce dryness and fatigue.
Relax with a view from afar
Every hour, look up from the screen and select a distant dotLike the view outside the window, quietly watch for a few minutes. This helps to reduce the focus pressure on the eyes and relaxes the eye muscles.
