Introduction of Shortwave Blue Light and TUV Certification of Low Blue Light

Nov 26,2022 | Jeff

Do you often have the following experience: After looking at the mobile phone for a day, your eyes are sore and tired. The reasons for this problem include poor eye habits, long-term viewing of electronic devices without rest, and poor adjustment of ambient light.

It may also be that your screen does not have a low blue light display level. Traditional display devices contain a lot of blue light, and the high-energy short-wave blue light with a wavelength of 415-455nm is easy to cause damage to the retina. If you are immersed in harmful blue light mapping for a long time, the macula will cause visual fatigue.

If the anti-blue light effect of the mobile phone itself is not strong, what method can we use to protect our eyes? Generally, there are two ways, software anti-Blu-ray and hardware anti-Blu-ray. Any anti-blue light eye protection mode that is turned on in the settings of the device is basically a software anti-blue light method. This method is realized by adjusting the blue light value in the pixels of the color board, which affects the display effect and causes color cast problems. The hardware anti-blue light is to change the short-wave blue light wavelength into a safe value, so the display effect will not be affected and the effect of filtering blue light is better.

It can be seen that the latter is a more ideal blue light filtering effect. Only the harmful short-wavelength blue light is filtered, while the beneficial long-wavelength blue light is left, which protects the eyes and does not cause the screen color to be warmer and yellower. The TUV Rheinland eye protection certification was created to achieve this effect.

At present, our protective film has obtained the low blue light certification of TUV, and the detailed report can be found in the document below the blog. The protective film with anti-blue light properties can reduce harmful short-wavelength blue light in the light propagation path, thereby reducing damage to human eyes.

Customers who have used our products have given us feedback: the TUV-certified low-blue light protective film is really useful. I used to have blurred vision and strained eyes after watching a mobile phone without a film for an hour. Now after using the film, I can watch it for 7 or 8 hours a day, and my eyes don't feel tired.

We are very happy to have achieved the level of customer satisfaction, and hope that more customers can use our products.
