UVtech Sleep-4B blue light blocking glasses, red

UVtech Sleep-4B computer glasses protect your eyes from the harmful light emitted by screens and displays. Thanks to their red lenses, they block up to 100% of blue and green light, which can disrupt the natural production of the sleep hormone melatonin in the evening. The polycarbonate frame features side shields that prevent unfiltered light from entering from the sides. It is recommended to wear them for approximately 1.5 hours before going to sleep.

Supports your natural sleep cycle

The main function of the UVtech Sleep-4B glasses is to prevent the disruption of melatonin production in the body. The blue and green light emitted by screens signals to the brain that it is daytime, suppressing the creation of this sleep hormone. The red lenses of the glasses filter out this entire spectrum, helping the body prepare for sleep. Furthermore, the frame is equipped with side shields that prevent distracting ambient light from entering, thereby increasing the effectiveness of the filtration.
