Anti-blue film

Introduction 

Since human beings entered the era of intelligence, more time is facing the screens of various smart devices every day, and screens like mobile phones and computers generate a lot of blue light.Blue light is the most energy-intensive part of visible light. Studies by authoritative institutions have shown that under long-term exposure to blue light, human eyes are subject to different degrees of damage, and long-term exposure to blue light can cause diseases such as biological clock disorder.

Nalinwei adopts advanced nanotechnology to develop anti-blue film, which can absorb and convert blue light emitted from light sources such as mobile phones, computers, televisions, and led lights without affecting visible light transmission. Blocking and achieving significant barrier effects can greatly reduce the threat of blue light to human health.




Features 

While ensuring high transparency, the blue light rejection rate reaches the industry leading level

Effectively blocking the short-wavelength blue light in the high-energy region with a wavelength of 450nm-470nm peculiar to white LED

High definition and low haze

Good surface smoothness


Application area

Mobile phone anti-blue light field

Home, office computer anti-blue light field

Anti-blue light glasses field

All places where blue light is required
