Do you need glasses for a computer?

How computer glasses work?

Not everyone likes to wear glasses, and there are a lot of reasons for that. Some people don’t think glasses are good for them, and some people are just not confident in their effectiveness. So, is it reasonable to buy glasses for working on the computer? Let’s find out.

Computer glasses can help protect the eyes from a variety of harmful factors that reduce vision, and sometimes lead to serious eye disease. Such factors include:

Working for a long time in front of the monitor when using computer glasses significantly reduces the visual load. The image becomes less “grainy”, which has a positive impact on vision. However, oddly enough, the picture is perceived with greater clarity.

When using glasses to work at the monitor significantly reduces fatigue of both eyes and the whole body, and significantly increases productivity. Computer glasses can be classified according to external parameters, lens coating, the presence of dioptres (people with normal vision are advised to use the so-called “zero”), etc.

What they are made of?

For the manufacture of computer glasses takes any (!) suitable for you frames for glasses, and special computer lenses. Exactly about it we write on the page of our site, where you can buy glasses for the computer. There you can choose inexpensive sunglasses, or conversely, the premium category. And in any case there is a special offer for purchase.

But let us get back to computer lenses. On the outer surface of such a lens has a special coating. Thanks to this coating, ultraviolet radiation is not harmful to the eyes, and the blue light exposure is reduced. The lens made in this way is able to reduce brightness and add contrast to the image, as well as remove glare. There is no need to strain your eyes all the time due to the clarity effect.

Benefits of wearing protective glasses

Wearing glasses while working at a computer provides undeniable benefits to those who use them:

• improvement of working capacity;
• Reducing the negative effects of computer radiation;
• eye surface anxiety (burning, tearfulness, irritation) is alleviated;
• Improve blood circulation in the tissues of the eye;
• the eyes are less susceptible to fatigue.

No harm in wearing special lenses has been detected. But there are some rules that should be observed regardless of whether the computer user wears protective glasses or not:

• Take a long break after being at the monitor for more than four hours;
• Maintain a distance of at least 50 centimeters from your eyes to the display;
• Adjust the monitor settings correctly;
• Include extra light in the room when working on a computer;
• Do short visual exercises at one-hour intervals.

How to choose computer glasses

When selecting optics to protect your vision when using gadgets, you need to consider:

What kind of optical products will suit you depends on the characteristics of the visual system, the presence of ophthalmic diseases. Each type of lens (monofocal, bifocal, progressive) is used for the correction of vision with different dysfunctions. To choose the right design, a consultation with an ophthalmologist is necessary.

Some models of computer glasses have an additional antireflective layer. It is designed to increase the user’s comfort when daylight hits the lens. Ophthalmologists recommend the use of non-darkened models. They provide high comfort during sudden changes in light.

At the same time, tinted lenses effectively block blue and purple light, which negatively affects your eye structure. People who work with printed materials are better to choose optics that increase contrast and soften halftones. When working with graphic images it is recommended to use products which improve color rendering.

Lens materials

To date, the vast majority of computer glasses are made from either mineral materials (different types of glass, close to the classic), or polymers (conditionally plastic).

If you look at the optical characteristics only glass is definitely better. it provides more accurate color rendering and refracts less light. Glass lenses are also good in their resistance to mechanical wear. they are virtually indifferent to wiping. Their disadvantage is low impact resistance and considerable weight. such optics puts heavy pressure on the bridge of the nose during the day.

Accordingly, the advantages and disadvantages of polymer lenses are completely opposite. Glasses with such lenses are very light, they are comfortable, and they do not crack at the slightest blow. but they can lose their transparency from wear.

Lenses of this type initially present a slightly worse picture, but it is fair to say that with the naked eye it is very difficult to see the difference.

Are there any contraindications to computer glasses??

Whether the computer glasses will be effective or, on the contrary, will cause you a lot of inconvenience, depends on both the correct choice of glasses and the way your workplace is organized.

When you buy glasses for a computer, check the quality of your vision. Computer glasses should not:

• Distort the shape and size of objects,
• Too much blackout,
• Limit the field of vision,
• create interference in front of the eyes (if the lenses are easily soiled or covered with scratches).

The task of computer glasses is to relax your eyes, not to give them additional problems. If you feel any discomfort with your glasses, it means you should not use them.

Yellow glasses. what’s the difference between regular computer glasses

Many people associate computer glasses with yellow lenses. And indeed, it used to be that way. The principle is based on the fact that yellow is a natural light filter that blocks blue. And the more intense the color toning, the less shades of blue. But the blue range isn’t all harmful, just the one that’s closer to violet. Modern manufacturers have now moved away from color (yellow) filters and focus on spectral. Not only do they win visually, but they cut off not all of the blue spectrum, but only the excess.

I have always had 100% vision, I only went to the oculist for a routine appointment. That all changed 2 1/2 years ago when I started actively working on the Internet.

Even then I knew that there were special computer glasses to protect your eyes. But I started to think about buying them quite recently, when my oculist diagnosed me with macular dystrophy of the retina of the right eye. And in general, I noticed that after 40 minutes of my eyes bake, mucosa dry, etc. д.

Went to two opticians who wanted to charge me as much as possible for a minimum of work. Vparivaya expensive glass, frames and expert advice. But I took a different path and I don’t regret it one bit. I went to the district clinic where I live.

How to choose computer or anti-computer glasses (whatever you like)? What to stop at?

I bought my glasses in an online store, but I was haunted by my doubts. Because they can push an ordinary glass, or the frame does not fit, and maybe not like it. I wasn’t going to walk around the streets wearing glasses, so I didn’t pay much attention to beauty. The most important thing was that they protect my eyes from ultraviolet radiation and make me feel comfortable.

How I chose glasses for computer work, my tips:1. I do not recommend buying glasses over the internet or from shady stores. There is a high probability of getting a completely useless product. To start I went to the eye doctor for a consultation at the health center. Where I had my vision checked carefully and the distance between my pupils. In the end it turned out that I needed regular lenses without dioptres.It was sorted out, the doctor advised me to go to a few opticians and find something I could afford. Then as it turned out they also had some points. That solved a lot of my problems.

When choosing lenses it does not matter if they are made of glass or plastic, the most important thing is that they should have an anti-computer coating.

Always watch that you feel comfortable in glasses, the frame in no case should not press or fall down. The temples should not press on the bridge of my nose. This is one more reason NOT to buy eyeglasses via internet and even more so second-hand glasses by the ad.

In the doctor’s office I tried 10 pairs, all of them twice and some even three or four times. I have settled on the most comfortable for me so far.

What’s the best lens for computer glasses?

Glass is easier to break2. Glass is heavier than plastic3. Plastic is more likely to be scratched and broken4. Plastic is lighter, which means it doesn’t put pressure on the bridge of my nose

Take your pick. I have glass and I don’t regret it one bit. No pressure on the bridge of my nose, after comparing my sunglasses with plastic lenses with computer glasses I concluded. That to me makes no difference.

Pluses of glasses for working at the computer:1. Computer glasses protect your eyes from harmful rays coming from the monitor screen.2. After a few hours of uninterrupted work at the computer my eyes are much less tired. The mucosa is no longer as dry and the burning is gone, which proves that the glasses work.3. Stylish and beautiful accessory

I understand that the power of suggestion has not been cancelled yet, and many do not believe that such glasses really work. But that’s your opinion and this is mine, I’m not imposing it on anyone, I’m just sharing my impressions. Even if it’s the power of self-humiliation or my wish that the glasses help me, but they work, my eyes feel good and that’s the most important thing for me.

I would recommend them for computer work!

I got them for only 300 hryvnia. But it’s an old-buy item, and they’re about 700 and up at the optician.

Computer Glasses VS Blue Light Glasses (Which Do You Need?)

And those who are still without computer glasses and have faced with dry mucosa, burning, tearing, and a feeling of a foreign object in the eye, I can recommend EFFECTIVE EYE Drops!

How computer glasses work?

Computer glasses have one major difference from glasses designed for other purposes. This is the Spectra blue ray blocking feature. The way of this blocking can be in two ways:

• Tinting. The tinted lenses have a distinct brownish tint to them. Such glasses were widely used a few years ago, until they were replaced by more modern technology.
• Reflective Coverage. Modern lenses with so-called blue blocker coatings block the blue-violet spectrum of the screen and reflect the light from the lenses themselves. These lenses are clear, but have a blue residual reflex.

In addition to blocking radiation, computer lenses also help reduce brightness from the screen and overhead lighting, thereby reducing eye strain. Computer glasses are real-life optics designed specifically for computer users, taking into account all of the above features of working at it.

The price of computer glasses. How not to overpay, but also not to buy a pacifier?

We have already written about how to choose computer glasses, what technology there is, and what suits who. Not to be repetitive, we recommend reading if you do not fully understand how they work. We’ll refer you to this information below.

Actually, what do you imagine under the concept of “computer glasses”? Or rather ask what is your expectation of them? Most often, people who are far from optics, but close to the computers, computer glasses are perceived as some additional accessory, like a computer mouse, USB flash drive or webcam. That is, kind of a necessary thing, but not necessarily expensive, and not necessarily right now, you can buy it later.

We will not speculate on the importance and urgency in this article, but we will catch the words “not necessarily expensive”. Is it really so?
