The difference between the lens anti -blue light and the non -blue light: different prices, different functions, and different effects.
What is the difference between lens -anti -blue light and non -blue light
Different prices
Anti -Blu -ray glasses are more expensive than blue light glasses.
Different functional
Anti -Blu -ray glasses are glasses that can prevent blue light stimulating the eyes. Special anti -blue light glasses can effectively isolate ultraviolet rays and radiation, and can filter blue light, suitable for use when watching computers or TV phones. Do not prevent Blu -ray eyes suitable for usually going out, writing homework and reading.
Different effects
Preventing blue light has no effect on preventing myopia and has a certain effect on preventing eye fatigue. However, Blu -ray will inhibit the secretion of melatonin, and melatonin is an important hormone that affects sleep. The known role is to promote sleep and adjust the time difference. Wearing blue light glasses before going to bed will not affect the quality of sleep, and it will affect sleep quality without blue glasses.
Blue light
Blu-ray, short-wave blue light is a relatively high energy light between 400nm-480nm. The blue light within the wavelength will increase the amount of toxins in the macular area in the eyes and seriously threaten our bottom health. Blu -ray induced blind eye disease. The current effective solution is to perform film treatment on TV. The anti -blue light film technology is very mature and the cost is very low, which can effectively prevent the blue light from penetrating. Here, it is particularly proposed that blue light is not all harmful blue light. What is really harmful is the blue light within 400 to 440, and the blue light between 480 and 500 nanometers has a role in adjusting biological rhythms, sleep, emotions, memory, etc. It is related to it, but it is beneficial to the human body. And whether the short -wave blue light will inevitably cause damage to the human eye, which is related to the exposure intensity and the time of the irradiation. When the illuminance reaches a certain degree, it can cause damage to the retina for more than two hours.
Source of Blu -ray
A large number of blue light is in the light of computer displays, fluorescent lamps, mobile phones, digital products, displays, LEDs, etc. The blue light within the wavelength will increase the amount of toxins in the macular area in the eyes and seriously threaten our eye health. Blu -ray of daily life can be seen everywhere, but the main source of harmful Blu -ray is the LED LCD screen. Now the LCD display uses LED backlight. Because the backlight needs the effect of white light, the industry uses blue LED mixed yellow fluorescent powder to form white light. Because the blue LED is a main hardware, the blue spectrum in the white light has a peak, which forms the problem of harmful blue light that we call.
Blu -ray harm
Damage eye structure
The harmful blue light has extremely high energy and can penetrate the lens to the retina directly, causing the retinal pigment epithelial cells to shrink or even die. The death of sensitive cells will cause visual decline or even completely lost, and this damage is irreversible. Blu -ray can also lead to macular lesions. The crystal experience in the human eyes will absorb some of the blue light gradually turbid to form cataracts, and most of the blue light will penetrate the lens, especially the children's crystal shape is clearer, which cannot effectively resist the blue light, which is more likely to cause macular lesions and cataracts.
Cause visual fatigue
Due to the short wavelength of Blu -ray, the focus point is not to fall in the center of the retina, but the position that is more advanced from the retina. In order to see clearly, the eyeballs are in a state of tension for a long time, causing visual fatigue. Long -term visual fatigue may lead to symptoms such as deepening myopia, recovery, proneness during reading, and inability to concentrate, affecting people's learning and work efficiency.
Affect sleep quality
Blu -ray can inhibit the secretion of melatonin, and melatonin is an important hormone that affects sleep. The current known role is to promote sleep and adjust jet lag. This can also explain why playing mobile phones or tablets before going to bed can cause the cause of sleep quality or even difficulty in falling asleep.
Anti -blue light glasses
Anti -Blu -ray glasses are glasses that can prevent blue light stimulating the eyes. Special anti -blue light glasses can effectively isolate ultraviolet rays and radiation, and can filter blue light, suitable for use when watching computers or TVs.
