Description

Blu-ray-resistant mobile phone screen cover and manufacturing method thereof

The invention relates to a blue light-proof mobile phone screen cover and a manufacturing method thereof.

With the widespread use of modern life mobile phones, and people's lives are increasingly inseparable from mobile phones, many people often use mobile phones to bring the symptoms of acidity, pain, tears and other uncomfortable symptoms, which are more serious. The eyesight is declining. These uncomfortable symptoms are caused by the harmful light of the eyes on the screen of the mobile phone for a long time. The light emitted by the screen of the mobile phone is the enemy of the eyes. In general, the screen supplier of the mobile phone reflects the color of the screen of the mobile phone. Contrast and saturation will increase the brightness of the light behind the screen of the phone, which will make the surface of the screen look like a piece of glass, improve the clarity, and it will also reflect the light like glass, but when the light shines on the screen It will increase the light reflection, especially when the consumer is using the mobile phone at night, the LED light will increase the light reflection to the screen of the mobile phone, which is easy to be hurt by the light to the eyes, and the symptoms of visual fatigue will slowly cause Vision loss and headache health problems, the "uncomfortable light" generated by the phone screen Illuminating our eyes can also cause vision system imbalance. The light emitted by the screen of the mobile phone makes our eyes uncomfortable because these light sources contain a large number of high-energy short-wave blue light with irregular frequencies. These short-wave blue light have energy to penetrate our eyeball crystals and reach the retina. The short-wave blue light continuously irradiates the retina and generates a large amount of free radical ions. These free radical ions will cause the pigment epithelial cells of the retina to die. The decline of epithelial cells will cause the photoreceptor cells to lack nutrients and cause visual impairment. These short-wave blue light also cause macular degeneration. The main cause, we face the blue light stimulation generated by the mobile phone screen for a long time, but we do not know that the blue wavelength is short and the energy is high, which may cause dry vision, photophobia, fatigue and other early-onset cataracts and spontaneous macular degeneration. Blue light accounts for about 50-60% of visible light, and blue light is one of the main causes of macular degeneration, which may lead to blindness. Blue light will stimulate the retina to produce a lot of free radical ions, causing the retinal pigment epithelium to shrink, and then cause the decline of light-sensitive cells. This is because we are in the information age, people can work and study without mobile phones, facing mobile phones. Screen The time is getting longer and longer, and the frequency of using the eyes is getting higher and higher. The eyes start to be sore, sore, and weeping. It tells us earnestly: our eyes have been hurt and need to be protected when using the phone. At present, the blue light, electromagnetic waves and free electrons emitted by the mobile phone screen will cause damage to the eyes. In order to protect the eyes, it must be filtered. At present, the method of filtering the blue light of the mobile phone screen is to apply a protective film on the surface of the mobile phone screen. The light transmittance tends to decrease, and the attached film is prone to scratches and affects the visual effect, and the anti-blue light effect is still not ideal. Most of the material of the screen cover of the mobile phone is plexiglass (polymethacrylate), which is easily broken and has poor impact resistance.

The object of the present invention is to provide a blue light-proof mobile phone screen cover and a manufacturing method thereof.
