Anti-Blu-ray, anti-Blu-ray these two groups of keywords, the mobile phone foil publicity page can always see its presence in the blue as if night became a sinner, wherever they were crusade.
But in fact, we really need to prevent Blu-ray it?
Where is the blue light?
Blue refers to the wavelength of 400 to 500 nanometers of electromagnetic waves, because of the shorter wavelength, blue energy is relatively high, penetrating power is relatively strong. Therefore, blue light has the ability to penetrate the cornea and lens, causing some damage to the retina of the eye.
And most of our daily use of mobile phone light source is the LED. The most clever is the LED light source and blue-based, if you want to improve the brightness, the intensity of blue light will increase. In recent years, the development of cell phone screen brightness is to go So Blu-ray is really becoming a big threat to our eyes.
Anti-Blu-ray necessary?
However, when talking about the dangers of blue light, do not forget there are two important indicators: illumination brightness and exposure time.
China National Institute of Standardization visual health laboratory in the United 14 years have done a large blue-ray retinal damage experiments, Retinal cells were continuously irradiated with blue light over 1500 lx for 3 hours , Retinal cells showed decreased vitality and apoptosis.
However, the brightness of our daily LED lighting generally does not exceed 600 lx , The phone's screen illumination even less reach this level.
Blu-ray do not have to say so? Can not say that, For long-term use of mobile phones, the Blu-ray or visual fatigue, Long-term use of the eyes or not good.
But compared to the mobile phone anti-blue foil film, real laboratory or suggest that you take a more reasonable approach to reduce the blue damage to the eyes, That is more rest, moderate eyes Use your cell phone continuously for 20 minutes, preferably in the distance of more than 20 seconds, to relax your eyes.
Blu-ray film in the end there is no use?
Although we do not need to talk about Blu-ray discoloration, but surely we also want to know the anti-blue cell phone membrane in the end there is no use here, the real laboratory on the high-speed everyone a cruel fact: anti-Blu-ray mobile phone membrane, really useless .
We consulted specifically with the staff of authoritative third-party labs who tested some of the commercially available Blu-ray-resistant tempering films and as a result, These films filter the blue light effect is minimal , And do not have the anti-Blu-ray film effect almost.
Anti-Blu-ray film is not feasible
Anti-Blu-ray film not only can not effectively filter the blue light, but also make the screen color cast, darken, the result is worth the candle.
In a nutshell, blue light is really harmful to our eyes, but the anti-blue film does not function to filter out blue light.
Not only use the mobile phone, we use the computer for a long time, watching TV, you should also use the appropriate eyes, every 20 minutes overlooking the moment, let the eyes get adequate rest.In addition, open the phone, the computer on the night mode, or buy anti-Blu-ray Glasses is also a viable prevention program.
Do not try night mode?
Visual fatigue, impaired vision of the pot can not really let the blue back.In everyday life, we should learn to use the eyes properly moderate, this is the best way to prevent Blu-ray, protect eyesight.
