The present invention relates to an eye protection screen, and more particularly to an eye protection arrangement for screen of an electronic tool and a manufacturing method thereof, wherein a screen enhancement arrangement and a blue light absorbing arrangement are provided on a screen substrate not only to enhance the rigidity and light transmission of the screen substrate, but also to reduce ocular photochemical damage by blocking the blue light penetrating through the screen substrate.
Electronic devices are indispensable for our daily lives. People use computers for work, play video games and watch TVs during their leisure time and etc. Since many people spend a vast portion of their daily lives fixating on display screens of electronic devices, to protect a viewer's eyesight from excessive usage of any electronic device and prevent eye straining become a dramatic issue nowadays. Accordingly, such LED and computer background light (artificial light sources) are visible light which contains blue light. It has a short wavelength, with high frequency, and can directly penetrate the eye's lenses to the retina. In 40 years ago, scientists have found that the blue lights will damage our eyes. Over the past few decades, blue lights have already confirmed that it have a serious impact on human vision.
Recently, blue lights have a new evidence of making damages to our eyes. Blue lights will increase the light sensitivity of our visual cell and the photo oxidation thereof, so as to cause the death of the visual cells and the damage of our visions. Under aerobic conditions, the retina is stimulated by the blue lights to start the oxidation mechanism, so as to cause a severe oxidation reaction, which destroys the dynamic equilibrium of the oxidation of the body and cause the apoptosis of photoreceptor cells. It is considered that the reaction of the lipofuscin and the blue light are main reasons to cause the degeneration of the macular. A large numbers of experiments show that blue lights are able to activate the oxidation of retinal cells and initiate the apoptosis mechanism thereof, so as to cause the death and damage of the cell.
One of the most important factors in protection of the eyesight for electronic device viewers is to have an intermittent rest for their eyes follow a certain time of use. Another factor in protection of the eyesight for electronic device viewers is to provide a protection arrangement to block the blue light from the electronic device. The protection arrangement can be applied on either the lenses of the eyewear or the screen of the electronic device. However, such protection arrangement has several drawbacks. Accordingly, the protection arrangement will reduce the light transmission of the lens and/or screen such that the viewer will tend to increase the light intensity of the electronic device for increasing the brightness thereof. Especially when the protection arrangement is applied on the lenses of the eyewear, the wearer may feel uncomfortable by darkening the lenses. The protection arrangement can only applied onto the zero-power optical lens but not the long sighted lens, short sighted lens or reading lens. In addition, the protection arrangement does not provide any heat resistance, scratch resistance or strength of the lens or the screen.
The invention is advantageous in that it provides an eye protection arrangement for a screen of an electronic tool and a manufacturing method thereof, wherein a screen enhancement arrangement and a blue light absorbing arrangement are provided on a screen substrate not only to enhance the rigidity and light transmission of the screen substrate, but also to reduce ocular photochemical damage by blocking the blue light penetrating through the screen substrate.

Another advantage of the invention is to provide an eye protection arrangement and a manufacturing method thereof, wherein at least 12 membranes, including the light diffusion membranes and the blue light absorbing membranes, are applied on the surface of the screen substrate. Preferably, 15 membranes are applied on the surface of the screen substrate.
Another advantage of the invention is to provide an eye protection arrangement and a manufacturing method thereof, wherein the screen substrate is mixed with blue light absorbent for enhancing the blockage of the blue light penetrating through the screen substrate.
Another advantage of the invention is to provide an eye protection arrangement and a manufacturing method thereof, wherein the light diffusion membranes and the light diffusion membranes are applied on the screen substrate by vapor deposition.
