Blue Light Filtering Glasses

A pair of blue light filtering glasses protects your eyes from UV rays and filters blue-violet light, whether indoors or outdoors. When using digital screens, these glasses enhance your visual comfort.

What is Blue Light?

Sunlight consists of rays in various colors including red, orange, yellow, green, and blue, each with different energy levels and wavelengths. This is part of the electromagnetic spectrum. Blue light is within the visible light spectrum, with wavelengths ranging from 380 to 500 nanometers. There are three types of blue light:

  • Blue-violet light, with wavelengths around 400 to 455 nanometers.
  • Blue light from LEDs, with wavelengths around 430 to 470 nanometers.
  • Blue-turquoise light, with wavelengths around 460 to 500 nanometers.

Where is Blue Light Found?

The primary source of blue light is the sun, which means we are exposed to it when outdoors. However, we're also exposed to blue light indoors, through artificial lighting emitted by sources like LED lamps, energy-saving bulbs, or screens of digital devices. As a result, we are surrounded by blue light for a significant part of the day.

Is Blue Light Harmful to Our Eyes?

While the harmful effects of UV rays on health are well-established, researchers are currently studying the extent to which blue light may be detrimental to the eyes. There are many indications that blue light could be a risk factor for retinal aging and consequently, age-related macular degeneration (AMD). However, the development of this condition depends on various different risk factors, so further research is needed to determine how much natural and artificial blue light may be harmful to the retina.

How to Protect Against Potentially Harmful Blue Light?

One simple way to reduce exposure to blue light is to activate the dark mode on your mobile phone or generally decrease screen time. Additionally, whether you have a prescription or not, you can opt for glasses with a blue light filter. These glasses filter blue-violet light in the wavelength range of 400 to 455 nanometers and effectively absorb UVA and UVB rays. Glasses with this type of blue light filter coating naturally have a slight residual blue tint and a very light brown base tint. This mild base tint enhances contrast perception when looking at screens.

Who is Recommended to Wear Blue Light Filtering Glasses?

Since we are exposed to blue light both indoors and outdoors, blue light filtering glasses are suitable for everyone. Whether you work in an office or spend a lot of time outdoors, these glasses protect your eyes from UV rays and filter blue-violet light. Therefore, blue light filtering glasses are also a good choice if you don't have a vision problem and therefore don't need prescription glasses. In this case, you can choose blue light filtering glasses from Glasses24 even without vision correction.

Can I Wear My Blue Light Filtering Glasses All Day?

The blue light filter coating is an additional option that doesn't affect your vision correction. Therefore, you can wear your blue light filtering glasses from morning to night. This way, your eyes benefit from the protection of the blue light filter not only when working on a computer, but also when outdoors and exposed to sunlight.

Does the Blue Light Filter Only Work with Computer Glasses?

A pair of computer glasses is similar to progressive lenses, specially designed for your workstation. The near vision zone is adjusted based on the screen distance, suitable for individuals needing correction for both near and far vision. The blue light filter coating can be added not only to computer glasses, but also to regular single vision or progressive glasses. However, if you want a pair of computer glasses specifically designed for computer use, the blue light filter coating is an excellent complement.

How Do I Choose a Blue Light Filter?

At Glasses24, you can add a blue light filter to all frames, even without vision correction. Once you've selected your model, choose your lenses and simply add "Blue Light Filter" as a treatment option after entering your correction values and lens thickness.

Can I Equip My Existing Glasses with a Blue Light Filter?

Unfortunately, it's not possible to retroactively add a blue light filter coating to your existing glasses. Fortunately, at Glasses24, you can get glasses with a blue light filter starting from only €69.90.
