I believe that everyone is no stranger to this glasses. The heat in recent years is also very high. Customers have gone from entering the store to fear being fooled by the clerk to coming to the store to ask for anti-blue light glasses, but they don’t understand its actual function and effect. , Let's share with you some knowledge about "Blu-ray" today.
The source of "blue light": The harmful part here refers to the damage to human eyes in a short time or instant when the blue light radiance reaches Class 2 or Class 3 specified by the standard.
Daily life is also everywhere. Computer monitors, fluorescent lights, mobile phones, and LED screens of office workers; mobile phones, tablets, and game consoles passed by parents in order to prevent children from crying; all the hazards caused are the culprit that harms the health of the eyes.
The harm of "blue light": The harm of blue light to the human eye is mainly manifested in the eye pathological hazards and human rhythm hazards that lead to myopia, cataracts, and macular degeneration.
1. Blue light harms the first damage structure: Harmful blue light has extremely high energy and can penetrate the lens directly to the retina, causing the atrophy or even death of retinal pigment epithelial cells. The death of light-sensitive cells will result in decreased vision or even complete loss of vision. This damage is irreversible. Blue light can also cause macular degeneration. The lens of the human eye will absorb part of the blue light and gradually become cloudy to form cataracts, and most of the blue light will penetrate the lens, especially children's lenses are clearer and cannot effectively resist the blue light, which is more likely to cause macular degeneration and cataracts.
2. The second harm of blue light. Asthenopia: Due to the short wavelength of blue light, the focus point does not fall on the center of the retina, but a little bit ahead of the retina. To see clearly, the eyeballs will be in a state of tension for a long time, causing visual fatigue. Long-term visual fatigue may lead to symptoms such as deepening of myopia, double vision, ease of reading when reading, and inability to concentrate, which affects people’s learning and work efficiency.
3. The third harm of blue light. Poor sleep: Blue light can inhibit the secretion of melatonin, which is an important hormone that affects sleep. The currently known role is to promote sleep and regulate jet lag. This can also explain why playing with a mobile phone or tablet before going to bed can cause poor sleep quality or even difficulty falling asleep.
If the best way to prevent the harm of blue light is to leave these electronic products, but today’s living habits we can no longer leave, so we have to block these hazards and protect our eyes, then the safest and most effective method of protection It is to wear anti-blue glasses. When we choose this kind of products, we must choose regular and qualified products. However, most blue-ray glasses have a yellowish background. It is not recommended to wear anti-blue glasses for a long time in daily life, because it is anti-blue The glasses filter part of the blue light, and the picture will be yellow when viewing objects. It is recommended to wear two pairs of glasses, one pair of ordinary glasses for daily use, and a pair of anti-blue glasses for use when using a computer and other LED display digital products.
