Welcome to Monederosmart! Chances are that you, like us, spend a great deal of time working in front of your computer monitor. You are probably reading this on your computer. To help you avoid eyestrain and eyestrain, today we're going to talk about special computer glasses.

The computer boom is definitely on. More and more people depend on this tool to carry out their tasks. It is now possible to work from virtually anywhere with just a computer and an internet connection. However, all this can have an impact on our eyes.

Eyesight is a fragile sense that needs to be taken care of, particularly considering the amount of time we spend in front of the monitor. So, in this guide you'll learn everything you need to know about computer glasses. We'll show you the best models and go over key features and buying factors.




The most important things to know

  • Computer glasses are lenses specifically designed to prevent and reduce eye discomfort when working at the computer. They are very useful in combating CVS (computer vision syndrome), the symptoms of which include red eyes, fatigue, headache and blurred vision when working in front of a monitor.
  • Computer glasses can come with or without a prescription. Prescription lenses are only suitable for people who require them. Non-prescription lenses, however, are more universal and can be useful for anyone who experiences eyestrain and CVS symptoms when working at the computer.
  • The two most important features that good computer glasses should have are blue light filtering and anti-glare, as these are the main factors that cause eyestrain. It is also important to consider the manufacturing method and design. An eye exam will be able to tell you if you need prescription lenses.

Buying guide: what you need to know about computer glasses

If your eyes are already tired after reading this far, don't worry! It's time to take a look at the types of computer glasses available so you can quickly choose the ones that are right for you. You'll really feel the difference when working on your computer.

What are computer glasses and what are their advantages?

Computer glasses are an optical accessory that reduces eyestrain and protects the eyes when working in front of a computer. Their main purpose is to reduce the symptoms of computer vision syndrome, or CVS, which include tired and blurred vision, red eyes and headaches.

Although it may seem imperceptible, computers, like most electronic devices, emit blue light. This light, along with the glare and reflections of a screen, can tire and damage eyesight in the long term, particularly if the distance between the eye and the screen is small.

Computer glasses help to reduce and avoid these symptoms. Whether through prescription or simply blue light and glare filters, these lenses are highly effective in reducing the symptoms of CVS. This, in turn, can improve productivity and sleep quality.

Advantages
  • Reduce eyestrain and CVS symptoms
  • Fairly affordable
  • Available in many different designs
Disadvantages
  • Not suitable for everyday use
  • Do not filter UV rays
  • In some cases need to be customised

Prescription and non-prescription computer glasses - what should you look out for?

For many people, computer glasses are a necessity because of CVS symptoms, but not necessarily because of everyday vision problems. In other words, not everyone who wears computer glasses needs a prescription. Let's take a look at both options:

Prescription Computer Lenses: Like any normal lens, they can be bifocal, monofocal, trifocal or progressive. This is determined by an eye exam. Prescription alone can reduce the symptoms of CVS, although they should preferably also have anti-reflective and blue light filtering.

Non-prescription computer lenses: These have only a blue light filter and anti-reflective coating. This alone can help increase clarity when looking at the screen, even without a prescription, as fatigue and blurred vision are reduced.

Computer lenses and reading glasses - What's the difference?

Many people confuse computer glasses with reading glasses, but it should be noted that they are not the same. Although this guide deals exclusively with computer glasses, it is worth pointing out the differences between the two options to avoid making the wrong choice.

Computer lenses: These are designed to filter out blue light and reduce the effects of screen glare on the eye, preventing the symptoms of CVS. They are only prescribed if the wearer requires a prescription.

Reading glasses: They do have a slight magnification, but no blue light or glare filters. Reading text on a screen is very different from reading text on a printed page, as printed pages do not emit considerable light and glare. Their focal point is different from that of computer glasses.

Purchasing Criteria

Although they may seem simple, particularly those without a prescription, computer glasses have certain features that are important to consider. Here we list the most relevant buying factors to make your purchase as smart as possible.

Anti-reflective

it's important that your lenses have anti-glare

Since screen glare is one of the biggest factors that can affect your vision and cause CVS, it's important that your lenses have anti-glare. Since computer (non-prescription) lenses are relatively inexpensive, there are many low-quality options that may not have anti-reflective coating.

Unfortunately, there is no universal certification that lenses can be certified for this. The only way to be sure is to test them. To do this, you can point your lenses at a light source. If the light reflects slightly in different colours (instead of its original colour), the lenses are anti-reflective.

Blue Light Filter

Like anti-reflective, the blue light filter is essential to prevent eyestrain and ensure that you can spend long hours in front of your monitor without damaging your vision (remember, however, to always take breaks!).

The filter can vary the shades of blue (measured in wavelength) within the visible colour spectrum, so the key is to find lenses that feel natural. For this, you can search for "Blue Light Test" on the internet. You will find multiple image-based tests that you can use to check your filter.

Design and manufacturing

Design is a factor completely related to your personal style. Computer glasses come in all the most popular shapes, designs and models on the market, so there's an option for every wearer.

When it comes to workmanship, it pays to choose a model that is durable. There are many plastic models, but we recommend you opt for those made of stainless steel, carbon fibre, aluminium or polycarbonate. As well as being strong, these materials are also lightweight.

Prescription

not all computer glasses wearers require a prescription.

As mentioned above, not all computer glasses are prescription lenses, and not all computer glasses wearers require a prescription. It is worth consulting your optometrist about this, as well as having an eye test. If you do require prescription lenses, the most common types of lenses are as follows:

Monofocal: The magnification is constant over the entire surface of the lens, so they are comfortable and not inconvenient if prescribed as computer lenses. They allow you to maintain proper posture and distance from the monitor when using the computer.

Bifocals: They have two levels of magnification in the same lens. Although common in everyday use, they are uncommon as computer lenses. This is because they would be very uncomfortable, as you would have to tilt your head to see the monitor clearly.

Progressive: Although they have multiple prescriptions, the changes from one prescription to another are gradual. This means that if you need to use progressives to see the computer, this will not be inconvenient or uncomfortable as in the case of bifocals.
