Computer Glasses vs. Blue Light Glasses - Know the Difference

Computer Glasses vs. Blue Light Glasses - Know the Difference

You might have contemplated purchasing a set of safety glasses to use when using digital devices. When you come across all complicated jargon and diverse styles in the protective eyewear business, you undoubtedly step back.

There are many names and commercials that it's quite impossible to know and choose the most appropriate one for yourself. Computer glasses, blue light filter eyeglasses, etc. There are various options available.

Today, we'll compare the two and show the differences to help you reach an informed decision if you do decide to buy a pair.

Computer Glasses

Computer glasses, often known as computer screen glasses, are eyeglasses that shield the eyes from computer screens and other digital gadgets.

Computer Glasses

The primary goal of computer screen glasses is to alleviate digital eye strain. Digital eye strain (also known as Computer Vision Syndrome) is a group of vision and eye disorders caused by prolonged use of digital screens.

The common symptoms are as follows:

  • Blurred vision
  • Watery eyes
  • Headaches
  • dry eyes
  • fatigue

How do they work?

First, we must remember that there isn't any industry standard for what a pair of these glasses should do or have. Therefore the name "computer glasses" could apply to various things. With that in mind, computer glasses should not be classified as such unless they are capable of filtering out blue light.

When it concerns eye strain and damage, blue light is not the only problem, but it is the most common. The blue or turquoise light (400-495nm wavelength) released from displays causes the most damage to our eyes. This is because this wavelength carries substantially more energy than the others, putting additional pressure on our eyes and creating the difficulties mentioned above.

As a result, a pair of protective computer glasses should have a blue light filter, often known as blue-cut, that filters out blue light in the whole wavelength range (400-495nm).

A good pair of computer glasses will also have magnification and an anti-glare coating. It's also worth noting that these eyeglasses should only be given by an ophthalmologist who will analyse your eyes and recommend the optimal lenses. They are, however, quite safe to take without a prescription.

Blue Light Glasses

Blue light glasses come in two varieties: daytime and night-time. Daytime glasses are clear and sometimes referred to as computer glasses since they function in the same way as those stated above.

Night-time blue block lenses are coloured — commonly red or orange. The night-time variety blocks out the full blue light spectrum and is designed to be worn at night, as the name implies. These aren't meant to be worn in front of a screen; instead, they're designed to shield us from the blue light that remains after the sun has set, as any exposure to it throughout the night can interfere with our ability to sleep.

Blue Light Glasses

These tinted lenses ensure that none of it gets through, allowing you to fall asleep quickly when the time comes.

These can block green light with a wavelength of up to 550 nm; therefore, verify the spectral test reports before buying them to filter out the wavelengths they claim to.

Key Differences between the two

Let's look at the distinctions now that we've covered these two fundamentals. As you can see, there are a couple of them, but they aren't all that dissimilar.

The key distinction is that, unlike computer glasses, blue light glasses have to be worn both during the day and at night. Furthermore, blue block glasses only provide blue light protection – nothing more or less.

A good pair of computer glasses will have a decent pupillary distance, anti-glare coating, slight magnification, and blue light filtering. With this in mind, it's evident that the main goal of these glasses is reducing the digital eye strain, or DES, rather than only blocking out blue light.

In Summary

'Computer screen glasses' refers to any pair of spectacles designed to be worn while viewing screens or using digital gadgets. A blue light filter in your computer glasses is necessary when purchasing glasses for computer use. Blue light-blocking eyeglasses are only useful if they offer some protection from the complete spectrum of blue light.

The daylight blue block glasses are transparent and give protection from computer screens. As a result, they're known as computer glasses. To encourage sleep, blue light blocking eyeglasses for nighttime should be coloured and block 100% of blue light and 100% of green light over the full spectrum.
