What is the harm of “modern” technologies
Don’t feel alone if your eyes are dry, irritated, tired or out of focus right now, you’re not alone.
These symptoms along with head, neck and back pain plague many people these days. Almost 95% of Americans are at risk of the unique to our modern age “digital eye strain.”
The culprit behind these eye problems – uncomfortable in the short term and potentially dangerous in the long term – is the length of time we all spend staring at screens. The blue light on these screens affects our eyes.
Spending more than two hours a day in front of the monitor leads to the risk of eye problems. The American Residence conducts a survey involving 9,749 US representatives to find out how much time they spend in front of computers. They found that most people are in front of screens almost all of their time.
The report found that about 30% of adults spend nine hours a day in front of their televisions, computers, smartphones, tablets or other devices. More than 60% spend more than five hours, and nearly 95% more than two hours a day.
About 25% of children spend more than three hours a day in front of the screen. They are more susceptible to long-term eye damage than the elderly, and for this reason, special attention should be paid to them.
The screens of our devices emit blue light because it is so bright that it can be seen both in a dark room and in sunlight.
Prolonged staring at screens leads to the so-called computer vision syndrome. Almost all people can complain of dry, itchy or blurred eyes with the daily use of harmful devices.
But we’re now starting to study the longer-term effects of blue light, because they’re scarier.
Blue light reaches far into the retina, eventually causing damage and vision problems. It is the most common cause of these problems because we are often exposed to this type of light.
Also, there is some research that says that continuous exposure to blue light over long periods of time, especially in higher than normal daily doses, can potentially cause damage that causesmacular degeneration and cataracts .
Unfortunately for many of us, avoiding computer activity is impossible because it is part of our work and everyday life. But there are some things we can do to reduce the strain on our eyes.
Here are some tips on how we can reduce this tension:
1) When you stare at the screen, you forget to blink. It’s hard to do, but try to blink as often as possible.
2) It is recommended to increase the text size when necessary. Looking at small text, you narrow your eyes and bring your head closer to the screen, which is not a favorable condition for the normal functioning of your eyes.
3)After 20 minutes of work, it takes 20 seconds to look away from your screen. This helps to focus better.
4) The most important thing is to try to reduce the amount of time you spend exposed to blue light because it can permanently damage your vision.
