Blf Series - China
price: 1.00 Dollar US$
BLF Series is Blue blocking film for car window.
The BLF Car Window Film effectively filters out harmful blue light in the 400–450 nm range while retaining beneficial blue light between 450–500 nm, which can help improve mood and regulate sleep patterns.
This film utilizes "BLF Core Technology, " allowing for precise filtering of harmful blue light without affecting the transmission of other beneficial light spectrums.
In low-light conditions or at night, it also enhances nighttime driving safety.
In recent years, the Blue Light Blocking Window Film has gained increasing attention from car owners, primarily due to its protective effects on eyesight and overall well-being.
