Eye fatigue is a real scourge of the modern world.. Most likely, you spend a large part of the day looking at the screens of various electronic devices - your computer, smartphone, TV, and so on.. Staring at screens almost non-stop sooner or later leads to eye strain.. But the 20-20-20 rule can help you with this, according to Pannochka, an online publication for girls and women from 14 to 35 years old.. net What is the \?
If your job requires you to spend a lot of time staring at a computer screen, it's very likely that your optometrist has already told you about this rule.. It's actually very simple - for every 20 minutes spent in front of a computer screen, you need to look at something that is 20 feet away from you for 20 seconds..
How to tell if an object is 20 feet away from you?
If you don't have a tape measure handy, you can't accurately measure 20 feet.. But in fact, in this case, you do not need extreme accuracy at all.. Just focus your eyes on something far away from you.. For example, you can go to the window and look at a tree or a house across the street..
If you work in a confined space, go outside or into a larger space so you can relax your eyes..
Why exactly 20 seconds?
It takes about 20 seconds for your eyes to completely relax..
While you are resting and relaxing your eyes, pour a glass of water to replenish your body's fluids.. If there is no lack of water in your body, this will have a beneficial effect, including on your vision..
And if you can brew and drink a mug of green tea, it will help you even more.. Green tea contains a large amount of catechin antioxidants that enhance tear secretion and better lubrication of the eyes, preventing microtrauma and irritation of the eyeball..
Why You Need to Remind Yourself to Do This Every 20 Minutes?
Most likely, you look at the screens for a reason - when you do this, you are passionate about reading or work.. Therefore, you should set an alarm clock on your phone or computer that will remind you every 20 minutes that you need to take a break..
What do scientists say about this
The American Academy of Ophthalmology notes that constant and prolonged use of the screens of digital devices does not necessarily adversely affect your vision.. However, it can still cause a feeling of tension in the eye area and other unpleasant symptoms..
Under normal conditions, people blink about 15 times per minute.. When we look at a computer screen or a smartphone screen, this number is halved.. This can lead to dry, irritated and tired eyes..
Eye strain caused by the screens of electronic devices has quite an official name.. It's called Computer Vision Syndrome (CVS).. In a study published by the Nepalese Journal of Ophthalmology, researchers examined the effects of prolonged computer use on the vision of university students in Malaysia.. It turned out that almost 90% of the 795 students participating in the study began to complain of symptoms of VCS after just two hours of continuous use of the computer..
However, the same study found that frequent breaks during which students looked at distant objects significantly reduced these symptoms.. In other words, the 20-20-20 rule really works..
Although many doctors believe that the 20-20-20 rule is the best line of defense against VHCs, scientists point out that any break taken during the monotonous work of a computer or other electronic devices can do us good.. They also explain that children tend to be less likely to pay attention to the symptoms of VHC than adults.. That is why adults should carefully measure and dose the time spent by children behind the screens of electronic devices..
What are the main symptoms of eye strain?
The main symptoms of this condition are a feeling of dryness or burning in the eye area, as well as itchy eyelids..
Other symptoms include:.
• profuse tearing;
• blurred vision;
• double objects;
•headache;
• tension in the neck, shoulders or back;
•sensitivity to light;
• problems with concentration;
• "
Although these symptoms most likely indicate that you have overexerted yourself at the computer, if they persist after a long rest, they should be reported to your doctor..
How can all this be summed up?
Eye strain caused by working with computers and other electronic devices can be extremely annoying.. The 20-20-20 rule can both help you deal with the worst symptoms caused by this tension and reduce your uninterrupted screen time..
Even if this tension seems very strong to you, it is unlikely to cause a permanent deterioration in your vision.. And in most cases, the symptoms of CVD improve when you get a good rest..
How else can SCD be prevented
Want to reduce the impact of computer screens on your eyes? Then try to always follow these tips while working..
• Sit away from the screen. Try to sit at least at arm's length from him.. In addition, you should move the screen so that you look at it a little from top to bottom..
• To avoid screen reflections affecting your vision, consider switching to a matte screen display..
• Try to always remember the 20-20-20 rule. Set a timer to remind you to look at an object 20 feet away for 20 seconds every 20 minutes.
•Buy artificial tears at the pharmacy to avoid drying out the eyeballs..
•Try to blink more often to induce tearing.
• If your computer screen is much brighter than the lighting in the room where it is located, dim its brightness. Also, try to improve the lighting so that the contrast is less sharp..
•Try to keep your computer screen perfectly clean. If you have to look at an image through fingerprints and fly paw prints, it can only make your eyes more strained..
• If you wear contact lenses, it may cause the symptoms of dryness and irritation to worsen.. Try to give your eyes a rest at least once in a while by switching to glasses..
•Never sleep with contact lenses, even those listed as permanent wear.. Always wash your hands before removing or putting on lenses..
