Can I wear my Blueblocker glasses all day long?

Protecting your eyes from artificial blue light is a good idea. But should you wear your Blueblocker glasses all day long? We're often asked this question by customers, so we'd like to take a closer look.

Can I wear my Blueblocker glasses all day?

Our Blueblocker glasses should be worn in the evening hours after sunset. During the day, blue light is completely normal and helps to increase your dopamine, serotonin and cortisol levels. This is important for your general well-being. What is atypical, however, are the amounts of new light sources that often have a very high blue content (blue peak). This comes, for example, from Smartphones, laptops, computer screens, televisions or office lights.

Blue light - LED, smartphone, tablet, TV

This can also be very stressful for your eyes during the day. That's why there are also workplace or computer glasses. These have clear lenses and are designed to filter out only the peaks of the blue light spectrum. Such glasses make sense if you have to work at a screen a lot. If you are not sitting at a screen, it is best not to wear glasses at all during the day in order to get as much natural light as possible.

Should I wear blue blocker glasses outdoors?

No, if you are outside in natural sunlight, you should not wear blueblock glasses. The same applies indoors without artificial indoor lighting. For example, if you are sitting at home by the window reading a book (not on your tablet or smartphone), you should not wear glasses. The natural blue light from the sun is normal and good for you; you shouldn't filter it unnecessarily.

Don't block the sun's natural blue light

Sunlight during the day - sleep-wake rhythm

Our sleep-wake rhythm and our internal clock are significantly influenced by natural sunlight during the day. That's why it's important for us to get as much natural light as possible. So if you go outside during the day, you should not wear blue blocker glasses, as you will prevent the natural frequencies of the sun from reaching your eyes. This disrupts your circadian rhythm and can also affect your melatonin levels. Blueblocker glasses are designed to filter the blue light from your surroundings in the evening. After sunset, people used to have at most the light from a campfire or candles. The spectra we have today from all the devices and screens are not natural and suggest to our bodies that it is still daytime. With Blueblocker glasses, we can completely filter out these spectra and prepare our bodies for the sleep that lies ahead.

Why should I wear Blueblocker glasses in the evening?

The crucial and biggest problem with blue light after sunset is the effect it has on our bodies. After dark, the light fools our brain into thinking it's still daytime. This interrupts our sleep cycle and can have a negative effect on our health, especially over longer periods of time. Orange or yellow lenses, which block 100% of the blue spectrum (orange lenses even block a large part of the green spectrum), can help you improve the quality of your sleep.

Whether you are still sitting at the computer in the evening or watching a TV program, blue blocker glasses help you to relax your eyes. In addition, melatonin production is not inhibited by blue light. This makes you feel tired and can have a positive effect on your sleep.
