What is Blue light? The Blue light refers to light with a wavelength of 380-495 nm and it's a kind of visible light. Blue light is short and has high energy. It can penetrate the lens directly to the retina of the fundus. Bluelight is widely used in LED light sourced products such as PCs, Cell Phones, Tablets, Game machines and TVs. However, mobile phone screens, LEDs, and computer screen lights all generate a lot of blue light. This can cause harm to people's eyes and skins, and cause eye fatigue and may even cause age-related macular degeneration which not only resulting in visual fatigue, but also not conducive to normal sleep.

As good as it claims to be
A very good product. Does what it is supposed to do: you can notice the effects immediately after placing the filter onto the screen. My one reservation is that though the magnetic strip at the top is very effective, there are no means to keep the bottom of the filter snug to the screen. With my individual product, the bottom left of the filter will not sit plush and is noticeably raised from the monitor.

Useless almost impossible to install
It’s very very difficult to install this; given the poor quality of adhesive packs and instructions
