Eye health depends on whether you can control the load on your eyesight and provide your eyes with sufficient rest.
How do you know if your eyes need rest
Any visual discomfort suggests that it's time to take a break from work and give your eyes a chance to rest. Experts identify the main symptoms that indicate an overstrain of the visual system:
- shroud, mist before the eyes;
- the image doubles and blurs;
- eyes become inflamed and redden;
- increased tearing and sensitivity to bright light;
- possible painful sensations in the eyes – pain, burning, itching;
- there are problems with focusing at close range;
- possible eyelid twitching.
Be careful! These symptoms can signal the presence of severe visual impairment! To exclude negative scenarios, you need to visit an ophthalmologist.
Causes of increased visual fatigue
Why does vision deteriorate? The main reasons for this phenomenon are distinguished:
High eye strain. Schoolchildren and students, who read and write a lot, and office workers whose activities involve continuous sitting at a computer or reading documents often face this problem.
Also, if you are fond of computer games, like to watch a series on mobile gadgets – smartphones or tablets or spend all your free time with a book, your eyes are also under high stress.
It’s necessary to interrupt as often as possible and provide regular rest to the eyes to minimize problems.
Computer vision syndrome. It’s a whole complex of symptoms. They are caused by overstrain of the visual system due to prolonged computer use. The reason for the development of the symptoms is not the need to look at the monitor for a long time but a functional change in posture, eyes, and neck.
So that working behind the monitor screen doesn’t create problems for your health, you should protect your eyes in time by choosing and buying special protective computer glasses. With their help, you can comfortably work at the computer without fear of its adverse effects.
Glasses with a special protective coating are for working at a computer. Its operating principle is as follows:
- blocking of harmful blue and violet rays;
- elimination of glare on the monitor;
- flicker reduction;
- improving image quality and contrast.
Thanks to these properties of computer glasses, the eyes get less tired since they don’t have to be strained excessively, and they are protected from harmful radiation.
How to choose the right glasses for working at a computer
If you already have vision problems, be sure to consult an ophthalmologist. And if everything is in order with your eyes, and you don’t need lenses with diopters, then pay attention to the most common anti-reflective coating option.
To choose the right glasses for working at a computer, you should consider the following factors:
Lenses. The most important thing in computer glasses is the lenses. Their quality will depend on the safety level and protective properties of computer spectacles.
Before choosing computer glasses, be sure to check if the lenses have protective coatings:
- Anti-glare – to reduce the level of reflected light and glare.
- Anti-static, repels small dust particles and prevents computer glasses from getting dirty.
- Metallized (EMI coating) that blocks electromagnetic radiation.
- Blue Block filter that blocks blue and violet rays from the monitor screen.
The color of the lenses of computer glasses can be chosen differently – completely transparent, yellow, or green. It doesn’t affect the protective properties.
Frame. First, the frame should be comfortable and light and not create discomfort. Choose the frame model so that the light apertures are large enough and provide a good view.
But, even choosing the best glasses for your computer, don’t forget to follow these rules:
- periodically take breaks for a few minutes;
- try to blink more often;
- work in normal lighting conditions.
