Every day we use our smartphone, tablet, laptop or TV. It is not uncommon for people to complain of headaches and tired eyes after working for hours on the PC. Many also find it very difficult to fall asleep. But what could be the reason for this? What many people don't know is that the devices emit short-wave blue light, which is harmful to us and can often lead to the symptoms mentioned.

The blue light filter glasses provide a remedy in this context by filtering out the short-wave light. So that you know which blue light filter glasses actually help, we have compared many offers in our blue light filter glasses test 2021 and clearly summarised our findings and recommendations below.

Blue light filter glasses: Buying and evaluation criteria

When buying blue light filter glasses, you have to choose between a variety of models. To help you find the best glasses for you and make the right choice, we have compiled the most important buying and evaluation criteria here.

Now we would like to go into more detail on the individual criteria and explain what they are.

Visual acuity

Since it is important that you see clearly with your blue light filter glasses, we recommend that you have your eyes tested by an optician or ophthalmologist before you buy them. This way you will know which prescription is right for you and can buy the right blue light filter glasses based on this.

You simply put the clip-on glasses on your existing glasses.

If you already have glasses with your individual prescription, you can either buy new glasses with the desired blue light filter or a so-called clip-on with blue light filter.

This option is usually cheaper than a completely new pair of blue light filter glasses.

All those who do not have a visual impairment can also easily buy blue light filter glasses without prescription.

Blue light reduction

Since blue light filter glasses differ in how well they filter blue light, it is very important when buying blue light filter glasses to pay attention to how efficient the respective glasses are.

Blue light filter glasses should filter out a specific wavelength of light, namely short-wave light in the range of about 38 and 450 nanometres.

Artificial blue light, for example from your mobile phone or laptop, falls into this range and is particularly harmful to your eyes.

Other blue light, such as from the sun, is not harmful to us and is not filtered out by blue light filter glasses.

Intended use

Before you buy blue light filter glasses, it is of course important to know what you want to use them for.

Blue light filter glasses are also available with additional UV protection.

Most people need blue light filter glasses primarily for long hours of work in front of a computer screen. A simple pair of blue light filter glasses is suitable here.

However, if you also like to wear them in everyday life and are often outdoors, then a compact version of blue light filter glasses with additional UV protection may be suitable for you. This way, you also save an additional pair of sunglasses.

Optics

Last but not least, it is important that you like the design of the blue light filter glasses and that they suit you. Blue light filter glasses are available in a wide variety of designs, colours and shapes.

You can make it easy for yourself by consulting an optician. Here you can try on the glasses before you buy them.

Nevertheless, there is a much larger selection of blue light filter glasses online. Alternatively, many sellers offer a virtual try-on, where you can see the selected glasses on a picture of yourself. Depending on the provider, it is also possible to order glasses to try on at home.

Blue light filter glasses: Frequently asked questions and answers

In this section we have summarised the most frequently asked questions about blue filter glasses and answered them for you. So take a look, maybe one or two of them will help you!

Who are blue light filter glasses suitable for?

Blue light filter glasses filter out short-wave blue light that is harmful to you.

Natural blue light, as emitted by the sun, is basically not harmful. Rather, it ensures a natural bio-rhythm, i.e. a sleep-wake rhythm.

The artificial blue light, for example from your laptop, TV or mobile phone, disturbs the natural bio-rhythm. This can be seen, for example, in the fact that if you use your smartphone before going to bed, it is more difficult to fall asleep.

Artificial blue light can also cause our eyes to age more quickly and possibly lead to headaches.

If you still don't want to give up using your smartphone, laptop, etc., but at the same time want to take care of your health, we advise you to get blue light filter glasses.

What types of blue light filter glasses are there?

Blue light filter glasses are available in a variety of different models. We have summarised the most important ones here in a table:

Type description
Clip-on blue light filter glasses blue light filter attachment for separate glasses
Blue light filter glasses with coloured lenses provide a yellow-orange view through coloured lenses and usually contain high blue light filtering as well as UV protection
Blue light filter glasses with colourless lenses provide a natural view with a mostly average blue light filter

You can use these three options as a basis for your decision and choose the blue light filter glasses that suit your individual needs.

How much do blue light filter glasses cost?

Depending on the model, you can expect different prices. We have also created a small overview for this:

Type Price range
Clip-on blue light filter glasses 20 to 50 euros
Blue light filter glasses with coloured lenses 15 to 100 euros
Blue light filter glasses with colourless lenses 5 to 200 euros

Prices depend on various factors. Cheap glasses are easy to find on the internet, but whether the glasses will keep their function is rather uncertain. Good brand-name glasses from an optician are much more expensive by comparison. In addition, blue light filter glasses with an additional prescription usually cost extra and are therefore also somewhat more expensive.

Everyone must therefore decide for themselves how much they want to pay for blue light filter glasses. Although glasses from an optician are usually of better quality, you also pay extra for the brand name.

What are the alternatives to blue light filter glasses?

In principle, there is no direct alternative to blue light filter glasses. If you do not use blue light filter glasses, we recommend that you protect yourself indirectly from artificial blue light.

For example, you could do the following:

  • Reduce smartphone use
  • Don't use a smartphone or similar device for at least an hour before sleeping
  • Regulate the amount of blue light from your devices

Of course, you can also use these tips with blue light filter glasses and protect yourself twice!

Conclusion

With efficient blue light filter glasses, you can optimally protect yourself from harmful blue light. In this way, you can prevent unpleasant symptoms such as headaches or tired eyes after hours of PC work.

When buying blue light filter glasses, however, you should pay attention to various purchase criteria and in this way choose the right model for you. The glasses should not only look good, but also fulfil their purpose. Depending on the intended use, you can choose between different models and possibly save money.
