Demystifying Blue Light: Impact on Sleep and the Role of Blue Light Blocking Glasses

Demystifying Blue Light: Impact on Sleep and the Role of Blue Light Blocking Glasses
The popularity of electronic technology products has greatly improved people’s quality of life. However, did you know that while we enjoy the great convenience they bring us, high-tech electronic products also bring some adverse effects to our lives? For example, the blue light generated by electronic products will interfere with our sleep.

What is Blu-ray?

Blue light is a part of the visible spectrum with shorter wavelengths and higher energy, ranging from about 380 nanometers to 500 nanometers. Blue light has higher energy and stronger penetrating ability.

The main sources of blue light are: sunlight. During the day, the blue light in sunlight helps regulate the body’s biological clock and maintain normal circadian rhythms. Secondly, there are electronic devices such as mobile phones, tablets, computers, and TV screens, which emit a large amount of blue light. LED (Light Emitting Diode) lighting products are also common sources of blue light in modern life. LED lamps and displays usually emit a relatively high proportion of blue light. Finally, some fluorescent lamps also contain blue light. The fluorescent powder in traditional fluorescent tubes produces blue light when activated.
Blue light is an important factor in the biological clock. Moderate blue light helps maintain normal circadian rhythms and melatonin secretion. Overexposure to artificial light sources at night, especially blue light, may cause visual fatigue, dry eyes, headaches, interfere with our biological clock, and affect our sleep quality.

Application of blue light glasses

Due to the increasing exposure to artificial blue light from electronic devices and artificial lighting, we are concerned about the potential impact of blue light on the eyes and biological clock. Therefore, some people may take measures such as using blue light glasses or adjusting device settings to reduce excessive exposure to blue light.
The principle of blue light glasses mainly involves blue light filtering technology. Its lenses contain a special coating or additive that can absorb specific wavelengths of blue light. This helps reduce the amount of blue light entering the eyes. Through specially designed lenses, it slows down or filters the transmission of some blue light. This helps reduce the exposure of the eyes to blue light.
Secondly, it can also improve the visual experience by increasing contrast, making the text and images on the screen clearer, reducing eye fatigue, protecting or alleviating negative effects on our retina; at the same time, it helps to increase the secretion of melatonin while relieving eye fatigue, allowing us to have a better sleep after surfing the internet.
SLEEPON Blue Light Blocking Glasses is an excellent product designed based on this principle, which has significant significance in blocking/reducing the impact of blue light on us. It not only protects our eyes and releases fatigue, but also helps promote the secretion of melatonin in the body, thereby improving our bedtime and sleep quality. Click to learn more…
