As a text worker, I spend almost every day in front of a computer screen, which is similar to being a partner in the IT industry. I also purchased anti blue light glasses to protect my eyes.

Wearing blue light-resistant glasses is important! Anti-blue light glasses can effectively reduce the sustained damage of blue light to the eyes. Through comparative testing with a portable spectral analyzer, the intensity of blue light emitted by mobile phone screens is effectively suppressed after using anti-blue light glasses, reducing the harm of harmful blue light to the eyes.

What is blue light? Natural light is sunlight, which includes seven colors: red, orange, yellow, green, blue, blue, and purple. Blue light is the blue light inside, with a fluctuation range of 385nm to 505nm.

Due to the short wavelength of blue light, the focal point does not fall at the center of the retina, but rather closer to the retina. To see clearly, the eyeballs remain tense for a long time, causing visual fatigue. Long-term visual fatigue may lead to symptoms such as deepening myopia, diplopia, easy serialization during reading, and inability to concentrate, affecting people's learning and work efficiency.

Blue light inhibits the secretion of melatonin, an important hormone that affects sleep and is known to promote sleep and regulate jet lag. This can also explain why playing with a phone or tablet before bedtime can lead to poor sleep quality and even difficulty falling asleep.
