No Blue Light Glasses filter light. They only let through the harmless frequencies that induce sleep and block the blue (and green) frequencies that inhibit melatonin production. By allowing our body to produce melatonin, the sleep hormone, they allow us to fall asleep easily.

Sleep is made up of several phases. The phases that regenerate our body the most are those of deep sleep. To enter these phases it is necessary to go through the phases of light sleep. The greater melatonin produced thanks to the blocking of blue light, allows us to fall asleep earlier, enter the phases of light sleep earlier and then the deep ones. For this reason they allow us to rest and regenerate more, with the same hours of sleep.

Taking exogenous melatonin (i.e. in the form of a supplement/candy/drops etc.) may temporarily help with sleep problems, but it is not a recommended long-term solution. Promoting the natural production of melatonin (i.e. endogenous) is essential to maintain a healthy sleep-wake cycle. Endogenous production is essential for a natural and sustainable regulation of the circadian rhythm and for our body to “work” properly. Wearing No Blue Light Glasses in the evening allows you to produce exogenous (i.e. natural) melatonin, thus improving the quality of sleep without the need for supplements.

Yes, No Blue Light Glasses are safe to wear every day. Being a natural remedy, they only bring benefits to our body, without bringing any disadvantages. Unlike melatonin supplements, which are usually prescribed with the recommendation to suspend them for some periods to create addiction, No Blue Light Glasses are not habit-forming. They block harmful light and allow our body to function as it was designed by mother nature, without any kind of side effects. They are also CE approved and do not pose any risk to your eyes or your health.

You may notice the benefits of these glasses from the first night you wear them following the instructions in the "Fall Asleep in a Flash and Sleep Like a Dormouse" manual. However, in the case of chronic insomnia or severe cases, it may take up to 10 days for your body to reaccustom to the natural production of melatonin. In cases where exogenous melatonin has been taken for very long periods, it may take a few weeks. In any case, you will have our active support 7 days a week after purchase. We are so confident that the No Blue Light Glasses will work, that you will have up to 60 days to try them with our 100% satisfaction or money back guarantee. If you do not notice any benefits, we will refund you 100% and collect the No Blue Light Glasses at our expense.

Anyone who uses electronic devices in the evening or simple artificial lighting (LED, neon, light bulbs...) should wear glasses that block blue light to promote the natural production of melatonin and protect the eyes. They are particularly useful for those who suffer from sleep disorders or want to improve the quality of rest.

It is advisable to wear the No Blue Light Glasses two hours before going to bed to allow the production of melatonin and prepare the body for sleep.

Nowadays, children are exposed to huge amounts of blue light from electronic devices and artificial lighting. Their eyes are more delicate than those of adults. This is why it is especially important to protect their eyes and promote healthy sleep. Inside the manual "Fall Asleep in a Flash and Sleep Like a Log" you will find an entire section that explains how to protect children's (and newborn's) eyes from blue light.

No, however, we have developed a special clip to apply to your glasses so that they become No Blue Light Glasses! You can apply and remove the clip to your glasses in a second, so that it filters the light and your glasses can continue to do their job. This way you can save significantly compared to developing No Blue Light Glasses with prescription. The clip is easily applicable and removable, you can find the details in our shop.

Chronobiological glasses are specifically designed to optimize circadian health. Their lenses are particularly effective at blocking high-energy blue light, which is the most detrimental to melatonin production and sleep regulation. Other glasses with orange lenses can block only small percentages of blue light, providing little or no benefit.

Absolutely! Even if you don’t feel tired in the morning, blocking blue light still has many benefits. Prevention is key to maintaining quality sleep in the long run. Blue light emitted by electronic devices can interfere with the natural production of melatonin, the hormone that regulates your sleep-wake cycle. By wearing glasses that block blue light, you may find that you fall asleep more easily, enter deep sleep stages sooner, and wake up feeling even more rested. Many users notice a significant improvement in the quality of their sleep after starting to use these glasses. Even if you currently feel fine, preventing the potential negative effects of blue light will help you maintain healthy, restful sleep over time and not compromise your body’s ability to produce melatonin naturally.
