Computer glasses: benefit or harm

Increasingly, optician stores offer purportedly useful computer glasses. This type of product is designed specifically for computer use to protect your eyes. What are the benefits and harms of computer glasses? What properties do they have? What are the best computer glasses?

What are computer glasses for?

Computer glasses are specially designed to work on electronic devices with a display. Their lenses are coated with a special coating that helps keep the eyes from drying out and benefits vision. Manufacturers claim that their products, due to their special properties, are able to fully protect the visual organs.

The coating is a particularly useful filter. This filter blocks blue light and has monitor anti-flicker properties.

An antistatic layer protects the eyes from the harmful properties of the magnetic field.

Who is recommended to wear computer glasses

Computer glasses are recommended to be worn by users of various electronic gadgets in order to receive minimum harm from screen flicker, as they have protective properties.

They are especially necessary:

• people who constantly work with devices equipped with a display;
• persons with ophthalmic diseases;
• people with dry eye syndrome.

The benefits of using computer glasses

Regular use of computer glasses helps prevent many symptoms, namely:

• dryness of the cornea;
• carving;
• burning;
• overwork after exercising at the device;
• photophobia;
• the feeling of "grit" in the eyes.

A special coating has properties that prevent certain colors of the spectrum from reaching the retina, as a result of which the eyes are less tired and do not dry out. This has a beneficial effect on vision.

Do computer glasses help protect your eyes?

Dealing with the question of whether computer glasses are really useful for eye protection is not easy.

What is the use of anti-glare glasses for a computer?

For those who have to look at the screen for a long time, glasses are useful and even necessary. Eyes get tired quickly without a filter. In addition, eye fatigue provokes:

• the occurrence of headaches;
• irritability;
• decreased performance.

High-quality lenses tend to absorb blue radiation and are beneficial for focusing, thanks to which a person perceives the picture better on the screen. Anti-glare properties smooth out light reflections and do not irritate the eyes.

But for eye comfort, computer glasses alone are not enough. Eye damage will still be done. It is necessary to perform simple useful exercises for training the eye muscles, observe the rules of hygiene at the computer (the eyes should be at least 50 cm from the monitor, the back should be kept straight, the chair should correspond to the height of the person).Eye drops that reduce tension, reduce flicker damage, or moisturize the cornea can be useful protection.

But every person using glasses of this kind should keep in mind that wearing an accessory without breaks for rest, gymnastics, etc. will not benefit the eyesight. Rather, such a regime has negative properties.

It leads to decreased visual function. This is due to the fact that the lenses significantly soften the payload on the eyes, facilitate focusing, and the eye loses the habit of normal loads a little. If there is a benefit, then it is minimal, more often only harm is done.

How to choose the right computer glasses

Glasses are an accessory that should be selected individually in order to get more benefit from it than harm. Better to order glasses at an optician. In such establishments, everyone can try on many options for frames, choose the best one in color, material, suitable for the type of face. And from the pharmacy lenses will be more useful.

Points selection rules:

1. It is necessary to select several frame options and find out which one is more convenient and attractive.
2. When choosing a frame, it is important to consider the size. Some frames are produced for children, others for adults. It is important that the bows do not press on the ears and head, the nose pads should also not squeeze the nose. If the frame requires silicone nose pads, then they should be on the bridge of the nose, the ideal location for them is in the middle or slightly above the middle of the nose.
3. Lens size. It is recommended to give preference to frames that can accommodate wider lenses. They have good visibility properties. In glasses with narrow rectangular inserts, the view is much less.

It is also helpful to consult with an optician. Perhaps, in addition to the protective film, you need a useful anti-reflective coating or a moisture-resistant coating - a useful property for fogging lenses. And for people with visual impairments, glasses are made with both diopters and a protective coating.

Mineral - heavier and more durable, which is useful for wear resistance, less susceptible to mechanical damage; but they have properties of fragility, which is harmful for operation.

Plastic (acrylic) ones are lighter, but require multiple coatings in addition to basic shimmer protection. For example, plastic lenses are often coated with useful anti-reflective and anti-static films. They do not break so easily, but are more susceptible to mechanical damage (chips, scratches). This can ultimately affect the health of the retina, where the lens fragment can get.

Harm from computer glasses

Glasses can only be harmful if they are made of low-quality materials or when worn continuously without interruption.

The detrimental effect is visual impairment. When this symptom appears, it is necessary to contact an ophthalmologist who will select therapy and write down the visual regime.

Prevention of the development of computer syndrome

Computer syndrome develops due to non-compliance with the rules of work and rest. With constant and continuous work at an electronic device, redness of the eyes, double vision or flickering, a burning sensation or pain in the eyes, dryness, and decreased visual acuity may appear.

If even some symptoms appear, it is worth contacting an ophthalmologist, who will develop a visual regime and offer drops as a therapy.

To avoid the "computer syndrome", it is necessary to carry out prevention.

1. Take breaks from work in 20-25 minutes. You can interrupt less often, but for a longer time.
2. During rest, it is recommended to do a healthy eyelid massage and / or gymnastics, which will relax the muscles and improve blood flow.
3. When working at the computer, use glasses with a special protective coating.
4. Apply drops that moisturize the cornea of ​​the eye, otherwise it can dry out significantly, and serious damage to vision will be done.

Conclusion

Computer glasses are a wonderful invention. They really help the eyes when working at the computer: they reduce stress, protect the cornea from drying out - but you should not abuse computer glasses either. The benefits and harms of computer glasses are, in general, obvious.
