Description
Technical Field
The invention relates to the field of computer protection tools, in particular to a harmful blue light protection plate for a computer display screen.
Background
The optical experts consistently point out: the short-wave blue light has extremely high energy and can penetrate through crystalline lens to directly reach retina. Blue light irradiation of the retina produces free radicals which cause retinal pigment epithelial cell death, which results in the depletion of light-sensitive cells that lack nutrients and cause vision loss, and these losses are irreversible.
The blue light is visible everywhere in daily life, but the main source of the harmful blue light is the LED liquid crystal screen. Nowadays, the liquid crystal display screen adopts an LED backlight. Since the backlight needs the effect of white light, the blue LED is mixed with yellow phosphor to form white light. Since the blue LED is a host hardware, the blue spectrum of the white light has a peak, which creates what we said as a harmful blue light eye-hurting problem.
One of the hazards of blue light, harmful blue light is able to penetrate the lens to the retina, causing atrophy and even death of the retinal pigment epithelium. The death of light-sensitive cells will lead to a loss of vision or even complete loss, which is irreversible. Blue light can also cause macular degeneration. The lens in human eyes absorbs part of blue light and gradually becomes turbid to form cataract, most of the blue light penetrates through the lens, especially the lens of children is clear and cannot effectively resist the blue light, and therefore macular degeneration and cataract are easily caused.
The second is blue light harm, which causes asthenopia. Since the wavelength of blue light is short, the focal point does not fall on the center of the retina, but is located a little bit further forward from the retina. To see clearly, the eyeball is in a tense state for a long time, causing asthenopia. The long-time visual fatigue may cause the symptoms of deepening of myopia, appearing of diplopia, easy serialization during reading, incapability of concentrating attention and the like, thereby influencing the learning and working efficiency of people.
And the third hazard of blue light affects the sleep quality. Blue light can inhibit the secretion of melatonin which is an important hormone influencing sleep, the melatonin has the effects of promoting sleep and regulating jet lag, and the reduction of the melatonin secretion directly causes the reduction of the sleep quality or difficulty in falling asleep.
The blue light is harmful to the eye, and is easy to cause dizziness. Because short wavelength light has relatively high energy, it is refracted or reflected in multiple directions when encountering fine particles in the air, causing people to be dazzled and producing a feeling of vertigo.
However, the truly harmful blue light is the blue light with the wavelength within 400-440nm, while the blue light between 480-500 nm is not harmful, and also has the function of adjusting the biological rhythm, and is related to the sleep, emotion, memory and the like of people, so that the blue light is beneficial to the human body. Therefore, for computers commonly used by people, harmful blue light of a display screen of the computer needs to be filtered, so that the eyesight, physical and psychological health of people can be protected. However, no similar products are currently on the market.
