Blue light is a natural component of sunlight. Blue light is a range of the visible light spectrum located just before ultraviolet. Blue light has short wavelength and therefore produces a high amount of energy. It is common knowledge that ultraviolet (UV) light can be harmful for our eyes. To prevent this, we protect our eyes with sunglasses. Blue light in the range between 380nm and 500nm is also suspected of accelerating the aging process of our eyes.
In the sunlight, blue light regulates our hormone balance. This has an impact on many processes in the body. For example, it gives us a wake-up call in the morning. Sunlight is the main source of blue light, but there are also many man-made sources, such as our smartphone or computer displays. In fact, we are exposed to blue light several hours every day. This high exposure can be harmful to our eyes.
People working in front of a computer often suffer from fatigue and dry or watery eyes. This is caused by the high exposure to blue light.
Blue light glasses have a filter that absorbs blue light until 450nm. This reduces distracting stray light and improves our visual focus while reading.
